my buddy has a 74 AMC cj5. he wants to throw an sm420 in there. i also know that you guys use t18s a lot. ive seen both on the trail and am impressed. i have a 420 thats where he got the idea to gear down. so as far as adapter availability and pricing, and also ease of swaping wich is best?. hes mating it to his dana-20 t-case.
--- he doesnt wanna change t-case or anything right now...so just using this..what are his options?

What motor. Jeep motor then the 18 if it is a chevy motor then the 420

What transfercase? What motor?

T-18A
1st 6.32 2nd3.09 3rd1.69 4th1.00 Rev 7.44


SM-420
1st7.05 2nd3.58 3rd1.71 4th1.71 Rev7.05

If you are going to use a dana 300 your looking at a 4" adapter with the 18.

We need more specs??
In a cj-5 you really need to look at length in the rear drive shaft. With a stock jeep t-18a and a dana 20 my rear drive shaft was 17 3/4"

I've got a 79 CJ5 and I run the T-18a mated with a Dana 20. Not sure how long the rear driveshaft is, but there's plenty of room for this setup.

DCruiser138 posted for me because something happend to my computer. I have a AMC 304 For the engine and for a transfer case I have a Spicer/Dana 20. Which setup would be the best the T 18 os 420 and where could I find the adapters that I need to do the swap.

try novak industries they have a whole section on how to rework bellhousings clutch parts etc. as opposed to advance who just wants to sell you every thing

www.novak-adapt.com

You also may want to try partsmike. He had a couple of used adapters whan I bought mine.
I may be a newbie on this board but I have been running a 427, T-18, worm driven case (8 to 1), tube chassis, SOA, 9" and a 44 front for quite a while.

What tranny do you have in there now? I say T-18 just for the fact that you have the 304, your bell housing should be able to mount up to it without any adapters.

If you can find a T18 out of a Jeep with the stock adapter, your all set.

I have the T-14A 3 speed which is standard on all 74 CJ-5, but the T-18 was optional and who ever bought the Jeep when it was first built was to cheap to get the T-18 as an option. Also in a book I have it says there is a T-18A used in 76-79 Cj-5 what is the difference between the T-18 and The T-18A:confused:

If your using a 304 and a dana 20 stay away from the 420. It will be more costly and harder to find.

If you find a Jeep T-18A everything will bolt right up. If it doesn't come with a bellhousing you can moditfy a t-150 bellhousing.

Find a ford T-18. Then look for a Jeep t-150 bellhousing that will same you some money on a bellhousing adapter. All you will need then is the transfercase adapter

You know whats funny?

A jeep (I belive a t150) bell housnig can be modified to work on a sm420 by simply drilling two holes, With the 420 you will need an adapter for any t-case. thats really going to be your cost. Talk to eric at Novak Adapters, he is a very good guy to deal with and will help you out on the bell housing he has a complete FAQ on what bellhousing to get what clutch fork to get and what clutch to use

I have a 420 in mine just because the trannys are 20 bucks at the junk yard, Have you ever seen a t18a for 20 bucks?

At the time of my swap I went to a d300 just because I prefered the low gearing of it more so then the 20..

My drive shaft length was 16 inches with the 300, I'd imagine it will be longer with the 20.

I personally haven't found very many 420's in my travels through the local junkyards and was unaware that a T-150 bell housing would work with it. So my bad on the advice about the bellhousing.


Have you ever seen a t18a for 20 bucks?

Yep, I had a guy give me a ford t-18 for free. You can find them all day long around here for $20-$50

It all comes down to what you can find.

Okay lets clarify some things the stock bellhouseing will not work with the T-18a YES/NO. Also couldn't I just go to a Pick N Pull and find a 76-79 CJ-5 with the T-18 already in it with the adapter plate already on it and also take the bellhouseing if needed since those years used a spicer 20 t-case. I know that would be one hella of a find but is it possible.

I retract the last statement.
You are asking if anyone has ever seen a jeep t-18a for $20..............I agree. No...............But I have seen them for $500 or little less(the price of an adapter) So if you were to find a Jeep t-18a it would be about the same money as doing a Ford t-18 with the adapter.
.
.
.
(not saying the Dana 20 is better then the Dana 300. I just say this because this is what he said he was going to use)
If you get the adapter for a Dana 300 t-18 I think you have to have the transmission modified.(drill and tap 2 holes) Also when I talked to Some dude at Novak(about 3-4 months ago) He said the adapter and Dana 300 would add almost 5" to the lenght of the unit. Like I said I had a rear driveshaft of 17 3/4". I didn't feel I should make it any shorter. I was maxing out the driveshaft at full flex with SUA.

I say if you see hundreds of 420 laying around and you can buy one for $20 get it. Then you know you can get spare parts.

The 420 is a lower gear trans and we all love low. So...............
It all depends on what transfercase you want to use. (if a t-150 Bell housing can be used on the 420)

My $.02 :D

The stock t-150 bellhousing will work....I know for a fact. I know the SR-4 and t-5 bellhousing will not work (not that that matters:D)You said you had a T-14. Right??? I don't have a clue if that bellhousing will work or not.

Also couldn't I just go to a Pick N Pull and find a 76-79 CJ-5 with the T-18 already in it with the adapter plate already on it and also take the bellhouseing if needed since those years used a spicer 20 t-case. I know that would be one hella of a find but is it possible.
Anything is possible but not likely. They didn't put out very many Jeep T-18a. If you can find one get it............. I have a jeep t-18A in my Scrambler:D They are out there

so oviously I want the T-18a because of the lower gears in it but what type of vechicle could i find it in and where could I get the adapter plate for it to mate to my spicer 20 t-case. because novak is saying that they only have adapters for the t-18 ford transmission. they are confusing the hell out of me:confused: :confused: . also i know i can get the t-150 bell houseing out of 76-79 cj so that will be sorta easy to find.
Also whhat about linkage problems if i go with the T-18a will the old linkage work or will i have to modify it to get it to work

OK... You are more then likely not going to get a Jeep T-18a and if you did you wouldn't need any adapters. That is why Novak doesn't have adapters listed for it.

You will proably find Ford t-18's (note they made close band and wide band Fords also) THis is what Novak will make the adapters for.......

The linkage connects to the clutch fork at the Bell housing. So with that said the stock linkage should work.

Did this help?

one last thing when people say they are runing a T-18 in thier jeep like most people do they mean the T-18 from a Ford or from a jeep used between 71-75. Or do they mean the T-18A out of a jeep between 76-79 or what ever other vehicle they came in.

International also used a T-18:D

It all depends Close ratio?? Wide ratio?? They are all basically the same case. I think they used 3 different style main bearing in them, but they are all basically the same.

I have never seen a t18a in a pick and pull or yard unless it was a jeep yard and if I did see them there tehy went for 800 with the adapter..

I have (last saturday) seen 420s, about 6 when I stopped looking at yards, but then your looking at 450 for an adapter.. ITs all a wash..


To be honest both are good trannys, both will be just fine, Its all about whats avalible in your area..

Yep :D They all work it's just a matter of some blood, sweet, and Beers:D

Boy this question is being asked a lot lately. My advise would be if you are going to use the Dana 20 transfer case, then get yourself a T-18 from either a Full Size Jeep or a Scout. If you can find one for a 77-79 CJ, great, but they're rare and it will likely cost quite a bit. The FSJ or Scout T-18 should run about $250 or so and will have a factory adapter for the Dana 20. Then swap out the input shaft for a Ford input shaft and bolt it up using a modified T-150 or equivalent bellhousing. (I have no idea if your T-14 bell housing is equivilant.) None of the other granny low 4 speeds were ever used with the Dana 20 and are going to require the expensive adapter to bolt to the transfer case. The FSJ or Scout T-18 is the cheapest way to go. The only other things you are going to need will be a special extended pilot bushing ($20 from AA) and a Ford clutch disc.

One more thing, didn't the T-14 use a 10 spline output shaft? If so, you're also going to have to find a 6 spline bull gear to use with the T-18 tranny.

One more thing, didn't the T-14 use a 10 spline output shaft? If so, you're also going to have to find a 6 spline bull gear to use with the T-18 tranny.
where would I find this? Expensive? Hard to find?

Also Syko thanks for all the help with this and yes you clarified the questions for me.
I think I have finally figured it out but the only thing left I need to find out is if the T-14 bellhousing will fit to the T-18.
So my first choice is going to go find a T-18 out of a full size jeep and hopefully the adapter at some pick N pulls because I have a couple of connections with some in Sacramento and in Concord.
If that is a no go I guess I will go with the 420 as a last resort because my stock tranny is starting to go out as we speak (Grinding gears and that crap)

I am going to throw one more thought in the wash.Why not use the SM 465.These are easily found for cheap.And if you use the Novak adapter it is over 2" shorter overall than the 420.It also has a little lower 1st than the T18A.(6.54vs6.302)And there are 14 different versions of the T18 so you need to make sure you have the one you need.There are 3 versions of the 465.The 10 spline one being the most common and the one everyone adapts to.It will work with the stock 304 bellhousing with mods.Go check out Novak's site full of great info.I am going with SB chevy 465/20.Should work good!

Easy to find, it's the ten spline version that's hard to find. With a little luck you will find it attached to your donor tranny.

Hey, don't forget the NP-435. It has 6.69 first gear and uses a stock Jeep bellhousing. And are very common. They were used in Ford trucks from the mid 60's through the 80's. (You do want the Ford version for this.)

I have a 77-79 Original jeep T-18 for sale. It has the factory adapter to the 20, and the long pilot shaft so the factory pilot bushing will work. 6.32 to 1. I also have a factory T-18 bellhousing to go with it, and it is reinforced for a hydraulic clutch.

$600 for the tranny in perfict running order,
$75 for the bellhousing,
$75 for the hydraulic clutch set up
or everything for $675

I have a freind that could drop it off in Sac. on his way to Red Bluff, for a little gas money. He will be leaving phoenix around the second of Feb.

Hold up...The T-18 out of a fullsize has a longer input shaft. About 5" from a short shaft t-18. See pic You can use it but look at how long your rear driveshaft will be. Remember this is a Cj-5

As stated in an earlier post you would want to install a short input shaft if you get one from a fullsize

uhhh.>>> That is why I didn't list a price....oh and:flipoff2: :D

Now things are getting alittle bit confusing:confused:
okay since I can't get the T-18 out of a full sized jeep because of the longer output shaft what should I look in to get the proper T-18.
Since the T-18 has 14 different versions which one is the one I need to get so everything will work.
Okay now what about the 465 would that be easier than the T-18 and what could I find it in.

Okay someone just straight up tell me what I would have to do to get a T-18 into my jeep. where to get everything and any mods that would be needed.

Also what about the 465 and the 420?
Are they harder to swap in????????

Forget about Chevy tranny's. If you want a badass tranny then go with the NP435. Start a new thread about how to put one of those in. They are easy to find, I have 2 and could sell one, but they arn't as small as the T-18. BFD, they do have the lower 1st though.

To put the 465 or 420 in you would need to modify you bellhousing and usesome clutch parts from I think80-86 jeep.And you would need an adapter for the t-case.The 465 is the same length has the short input T-18 and novak's adapter is 1" long.So your driveshaft would be about the same length.The 420 is 2" shorter then the T-18 and 465 but the only adapters are 4" long, so this will shorten you shaft by 2".The 420 has the best low range but I doubt you would really notice the difference between the 3.I am going with the 465 because I have an extra laying around.I also have a 420 but I want to keep the driveshaft length.This gets to be a problem with the Cj-5s.I have a buddy who wants to go with the T-18.But its hard to find the right one for this application.If you do find one it is expensive like jonscj7 has his priced at.For this price I can go with either of the chevy trans I have.If I can convince my buddy of this he could have the one I don't use.Just my opinion.Blazin:rasta:

I couldn't decide whether I liked the 420 or the T18 (19) better so I installed both into my Willys

I have a 420 to T19 to Dana 20.........
When I was looking for a t-18/19 I found that the Jeep ones were sure precious to the Wreckers.......

It seems to me that the cheap way to pull off the Jeep T18 swap would be to get a 2wd Ford T18 (for the case and the gears) and get a Scout T19 tranny and transfer (for the Trans mainshaft and adapter)
Combine the two and you would have the elusive Jeep T-18/Dana20
:D

I already went throught this, but here it goes again. Get a T-18 out of a Scout or a Full size Jeep. They run about $250 around here. Make sure you get the D20 adapter with it. Don't worry about the input shaft just make sure it's a 6 to 1 tranny and not a 4 to 1. Next get a Ford T-18 input shaft. A new one will run about $100, a used one will run about $50. I myself got an entire 2wd Ford tranny for $50. You will also need the Ford input bearing retainer, $20; An extended pilot bushing, $20 from AA and maybe a clutch disk depending on what you have now. Now, swap out the old input shaft for the Ford one, line the tranny up on you old bellhousing, and drill and tap the attaching holes and bolt it up and go.

Not harder, just more expensive. The SM465, SM420, and the NP435 are all good trannys. Some might say better because they do have slightly lower first gears. They are all similar in size, but none of them ever came with a D20 attached. Therefore all of them require you to use an aftermarket adapter to mate up you transfer case. This adapter runs about $500 new for any of the above.

So to recap, to get a FSJ or Scout T-18 ready to bolt up costs $90-$140 plus whatever you have to do for a clutch disk.

To get an SM465, SM420, Ford NP435, or Ford T-18 ready to bolt in costs $500 for a transfer case adapter plus whatever else you have to do on the clutch end. If you run across one for free, then it might make sense, but if you have to pay very much for it, forget it. Also you might be able to find a used adapter like the one BossGrip has, but it would have to be pretty cheap to make it cheaper than the FSJ/Scout option.

This would work too, especially if all you could find was a 4 to 1 scout tranny, but if you manage to find a 6 to 1 Scout or FSJ tranny, then all you need is the short Ford input shaft. If you can find an entire Ford tranny for cheap, great, but all you really need is the input shaft and bearing retainer.

As always Jon

You want the "full" salvage yard version?

It can be done, just alot of work. Shopping list:

1- T-18 from 70's vintage Ford 2wd PU. You can tell the T-18 from the NP435 easily. The T-18 has a cast iron shift tower, 435's are aluminum. This gets you the proper length input shaft tranny, read short and the right mounting pattern for the bell housing. This is the Tranny the adapter places sell their kits for.

1- T-18 from same vintage Scout or FSJ. Watch the Scouts as you will find one of four posible trannies. 2 T-18's, 2 T-19's. You can tell a 18 fom a 19 easily. The 19 has the PTO side cover on both sides, 18 only one side.

1- T-150 bellhousing.

Throw all parts in a large sauce pan on medium heat, stirring occasionaly. Cook until done... :D

So with that this in mind you swap the outputs (IH into Ford) and rear bearing retainers. (Same thing you are going to do with the NOVAK or AA adapter) There is one minor snag, but it's easy to over come. The IH rear bearing retainer AKA the adapter doesn't match the back of the Ford case exactly. 2 of the bolt holes don't line up. Simple to fix. When you have the tranny dis-assembled to swap the output shaft, install the bearing retainer on the empty case. Bolt it up with the bolts that do line up then mark the retainer from the inside of the case, center punch, and then drill. Simple. Follow NOVAK's FAQ's for the bellhousing and clutch mods.


Make sure when you pull the Sprout T-18 you keep the bull gear that was attached to the tranny. Then you have the 6 spline gear you need for the 20 to bolt up.

It's a lot of work, T-18's are HEAVY, but this will net you the "cheapest" setup. Depends on if you value your time or not, and what you can get the donor parts for.

I say forget about the Jeep CJ specific T-18, they are hard to find and everyone thinks they are made of gold. The offer posted earlier is a fair price though, I've seen them over a 1000!

OOPs!! Sorry Oliver should have read all the way to the bottom before doing all that hunting and pecking...:D

Yup that's the point I was trying to make. Take a 6:1 FSJ or Scout T-18 swap the input shaft and it's as good as the CJ T-18.
:D

This will get you!!Talk about lucky!!!My buddy just got a T-18/20 short shaft and front and rear waggy 44s for $50!!!Thats $50 not $500!!Won't sell either.Putting them in the wifes Comando.Oh yeah and aluminuim rims also.Blazin

I was just fawkin with you. Have a little thicker skin.

First this is not the for sale section hense the :flipoff2:

The guy was asking for tech help, not does any one have a t-18 I can buy. Maybe I'm wrong but shouldn't you have PM'd him saying hey I hear your looking for a t-18 I got one for sale.
Any way it doesn't matter what I think the moderator didn't say anything. So be it.

ok...so what about the 435. more info on this. i would start another post about it, but ill see what kinda relpys i get here. if its lame...ill start another subject on it. thanks!

--- with this inquiry, im also gonna need to know adapter places/companies for this. im guessing NOVAK again...right? remember...i want this to be asd cheep and possibly easy as possible. :zzz:

http://www.novak-adapt.com/knowledge/transmission_gateway.htm

Go to these pages and read them. They should answer most of your questions

I think I have finally made a decision to go with the Np435 it seems the easiest to do and it also has a lower crwal ratio than the T-18. Can this tranny hold up to wheelin is my last question.??????????????
BUt during this process if some how i come across the T-18 with the adapter on it for cheap that is the way I will go.(can you say miracle)

Alright, point well taken. Next time I will suggest I have something for sale through a PM. I only posted it because everyone said that they were hard to find so I thought it might be alright to say they are still out there. But yes the thicker skin commet will not be overlooked but I find it hard to tell emotions with words.

Thanks for the comment.

Yeah, it will hold up just fine as will any of the other granny trannys. They were all used in up to 2 ton trucks. NP435 is a good choice. It's supposed to shift a little better that the others. Check with Novak or whoever is making your adapter. I think you have to have the 2WD Ford version.

CRO, can you at least tell us HOW you did it? Who made your adapter between the two trannys? Is this in a CJ or a Wagon? Did you have to strech the wheel base?
These are very good questions.

Come awn CRO you have answers we all need to know.

I crawled under the Jeep ........It's still not yet done and is in 'winter storage....or my version of it anyway.

The Adapter was made by Me......... (or OTTindustries if you prefer...I am a partner..)

Bad pic showing the length of the Adapter........4.375 inches between trannys

the whole thing from Bellhousing to output flange on the Dana20 is around 37" long..........YES the wheelbase and body are streched on the Willys.......the Body has a 7" stretch
I have a GM 4.3 V6 bolted to the other side of the Lakewood scattershield.
the fan is right up tight (1') from the Mustang rad on the Willys grille (cut down ...)

I will be running a Carrier bearing in the front driveshaft ( to keep the belly as flat as possible..
there is still enough room for a 18 " rear driveshaft (going from the D20 to the GM 14 bolt.....)

If you use the Advanced Adapter, you can use either the 2wd or 4wd NP-435.

BTW, it added only 1" to my drivetrain.

CRO, that is cool! Is this the same Jeep that formerly had the Toyota tranny coupled to the T-90? You must have a crawl ratio of about 400:1 with that setup. Damn!

Yep it's the same Jeep
I grenaded the T90 input gear about a year ago...........you know how these Jeep buildups start.........
I was tired of worrying about tranny strength and I wanted to go with a bigger engine (formerly had 4cylinder 22re toy motor)

The really low gears are only in Dual reverse...........Going forwards I should get to 400:1
Regular First-First-low+axle=7.05 x 6.32 x 2 x 4.10=365:1

I will likely leave the 420 in fourth and drive with the full synchro T19 most of the time...:D
