T-18 Questions.

Does any one know if the T18 with the 6.32:1 1st gear ratio was ever oem for Jeeps?
I just picked up one that supposedly is. I have read the Moses Ludel chapter on Tranny's and he makes it sound like this gear ratio was only found in Ford 2wd trucks and the Jeep T-18 was 4.01:1.
The guy said this tranny was out of a 1977 Cherokee(sp?) and he assureed me it was 6.32:1. Did I get suckered?
I am planning to swap this into a 1973 Cj with amc 304 and Dana 20 tcase.
Any and all help is greatly appreciated.
I would have searched but it is down.
Thanks
RocDoc

6.32:1 came in Jeeps.

You'll need to change out the input shaft with something shorter - those FSJ trannies had something like a 10 inch or longer input and a goofy adapter between tranny and bell-housing, too long for a CJ. What you have is not ideal. I hope you didn't spend too much on it 'cuz you'll have to spend more to get it fitted.

Novak has good info on T18 swaps. I think AA makes a suitable input shaft; doubt it's cheap.

If you got it cheap, then it might make more sense to get a Ford 2WD T18 and swap your Jeep mainshaft into it, and drill the rear of the Ford case to accept the Dana20 adapter (you DID get the Xfr-Case adapter, right?) Ford T18's bolt right on to an unmodified CJ T150 bell housing.

I had one that came out of a 70's j-20 pickup and it had the 6-1 first gear and a dana 20 transfercase
stick it in first and spin the input shaft 6 times and the output should turn one time

Every FSJ I have seen or heard of w/ a T-18 had the 6.32 1st gear.
Jeeps w/ the 4.01 1st gear came out of CJs.

If U got the bellhousing w/ the tranny should bolt right to the 304 from what I understand but U still need to get a shorter mainshaft to get rid of the long adapter found in FSJ.

Thanks for all the help,... do you guys ever sleep?
CrustyJeep, the Tranny came with a dana 20 still attached and an extra one to boot (t-case).
I'm gonna clean her up in the am and spin the shaft in first gear and count.
Thanks again Heres to ya!

There was a place called Hicks 4x4 that sold all the parts as a kit to do the input. conversion. I had good luck with them but their website is down or moved. I belive the place was called Hicks 4x4 & muffler in CA. If you need the # I can dig through my reciets tonight and try and find it.

AUbigmac,
Any help is great. I am in CA and I think all I need is the shorther shaft.
I have the bellhousing and cross member. I am hoping a shorter shaft will allow me to bolt it up.
Thanks again

I'll look this evening when I get home. I tried locally to find everthing I needed but and got a good deal on the imput shaft but the problem I had was finding the right 3rd/4th gear syncro block ring that rides on the input. The one for the long shaft is different than the short shaft. If I had it to do over I would just by the kit. In order to pull the input you have to pull the main shaft out of the trany so if it was me I'd replace the bearings while I was at it.

Full size Jeeps with the V8 had the really long input shaft with the adapter between the bellhousing and tranny. The ones that had a six cylinder just had a deeper bellhousing and the input shaft isn't as long. It's not as short as the Ford input, but isn't so long that they can't be used as is in a CJ.

CJ's from '77-79 also had the 6.32 gearing and have a very short input shaft. They are hard to find though.

You will need a bellhousing as your '73 should have a T15 which has a unique bolt pattern and depth for the input.

Once again thanks for the help.
The Tranny is a 6.32:1 ( I put it in first and spun it as advised) with a very long input shaft.
I contacted Novak they have a complete adapter kit $182.00, that is NOT on the web site, you have to talk to the Tech dept. and they custom build you a parts list to fit your jeep.
When I got the tranny I also got a T-case already bolted onto the tranny and the bellhousing. I am working tonight but will take out my tranny in the am.
I am hearing that I should use the bellhousing I got from the purchase.

Parts Mike has a short shaft kit listed on his site. He also shows 2 different front bearings for the T-18.

On don't think a T18 will go in a roller skate.

Broncos (4WD) had 'em, because my '79 did. So did V-8 CJ's on that era.

The short shaft kit is still available from parts mike. I couldn't tell from that post exactly what bell-housing you have, but I don't think the short one would be to hard to find if you don't have it.

I have a ford t18 and jeep dana 300 in my cj5, so it will fit. The rear driveshaft is short however, only 2" of tube between the cv and the slip. That is with the rear axle 1.5" back from the factory location.
