what trans for my jeep?

[Chrisjeep7]

well i have a 4.0 in my TJ and just exploded my trans (i ran a 176 just cuz i had it laying around and my ax-15 was dead)

i am looking at swaping in a cheap strong tranny
#1 it dont have to be a OD tranny
#2 manual or auto dont matter i like them both
#3 cheap
#4 has to be able to mate to a dana 300...fairly cheaply.

i was thinking np435 with the novac (or aa) adapter but
just wondering if anyone would swap in somthing else...

[JohnnyJ]

Wow, what are you doing to blow up trannies?

I've had good luck so far with my nv3550, how would that compare in price to a np435 after buying an adapter? Also, what about the CPS?

I guess with used parts, price will always come down to who you know or if you stumble on a good deal.

i have blown 2 nv3550's i wouldn't recommend running one. if you are going to run used why not just get the 4500 then?

cps no big deal, just learn how to fabricate. Nv3500 = maybe nv4500 = nope

What are you guys doing to gernade multiple trannies? Maybe it's just me, but if you are blowing new trannies, you need to learn how to drive. Auto's, change your gearing, but with a stick..dayum.

[Chrisjeep7]

mmm my ax-15 had 175,000 on it. the USED t-176 had god knows how many miles on it. i blew my t-176 up by backing up, not even that hard.

what does a nv3500 go for?

[Robert]

I run a T98 behind my 4.0L.
6.6:1 first gear is nice in the rocks. AA makes a bell housing to run these and the other T series granny trannies (T18/19/98). Depending on what you get, there maybe input shaft changes though.
If you don't want to buy the AA bell (I don't blame you one bit either), CJ bellhousings will work. Just require some reworking for your CPS.
Later model CJ with AMC V8 or I6, T5 or similar tranny, slave cylinder from a 81 CJ5 with the Iron Duke GM four cylinder (2.5L), GM 10" clutch disc, your current flywheel and pressure plate. The only bitch with this swap is I always have to have a pilot bushing cut for me. Just find something with the right inner diameter, then have a machine shop trim down the outer diameter to fit.
Parts Mike carries new new aftermarket CJ bellhousings, and all the slave cylinder junk you will need, for less than AA wants.

How about an AW4? It meets all of your criteria: cheap, auto w/ od, easily mated to a D300, and actually a tough trans. If you decide to use one you can even bypass using the TCU with one of these - /forum/jeep-hardcore-tech/242965-new-auto-tranny-option-jeeps.html and here - http://awshifting.bravehost.com/

Just an idea. I use the AW4 shifter and love it. It makes swapping trans easy and gives you the ability of picking what gear you want to be in. This is great for compression breaking and may trail situations that a manual could leave you wishing you had a third foot. Good luck, Judd

[Chrisjeep7]

yeah the aw4 is a good tranny but if i go auto i want it to be auto, as in i dont what to shift it all the time.

Just throwing out ideas, doesn't mean ya have to like it

Good luck, what trans are you thinking of running? Judd

[FatMeats12]

how about an sm465? aa sales adapters and its I think 6.55 first gear but then you need an adapter for the d300.

[Chrisjeep7]

thats 2 adapters compared to 1 for most trannys....

i was not shooting you down i was just saying judd. i am thinking np435, 999, nv3550...

[Myanarchy]

What about a 727. Strong, readily available, and shouldn't be hard for the 300.

Also what about the 999?

[Tall Grille]

NP-435 and T-18 are both strong, Cheap, well geared and can be bolted to the 4.0 with minimal fab work, Adapters are available for the 300, or you can fab your own NP-435 - EBD20 adapter fairly easily.

[mdoffroad]

Havent killed THIS AW4 yet, last one wasnt happy thoguh

[BannedWagoneer]

Semi-Hijack - You didn't by chance use the AX-15 hydro clutch actuator for the T-176 did ya? If so, what was involved in maiking it work? I'm gonna swap a T-176 for an AX-15 this week and would like to keep the hydro clutch if possible.

Thanx.

[Rebel GP]

I'd go for the 999. 300 bolts right up & plentiful in yards. I run an 86 CJ one..no probs with it, light and takes abuse.

[Chrisjeep7]

i used the hydo slave and the stock fork and just fabbed a braket to make it work, it was easy

[YJ4RoX]

go for the np435, cheap strong and short, nice tranny's.

[sceep]

if you have the room for an OD slushbox, I've been more than impressed with my 46rh.

Should bolt right into your 4.0/300 with no adapters.
