t-18 length question

i have a t18 from a 6 cyl j10, will that one inch spacer make it too long to use in my cj5 with a 92" wheelbase? The rear axle is apprximately 5 inches rearward of stock.

Re: t-18 length question

The answer lies in the length the rear driveshaft will be. Can you figure that out?

Re: t-18 length question

Assume you mean the 1" adapter on the rear? It's for mating up to your Transfer Case (Dana 20) If your going with something else like a Dana 300, your going to need a different adapter. It's also for the mounting to the cross member.
Your not giving us much to go on here, you ask about length being too long???? The T-18 is one of the shortest trannys out there? Like Lou said, just measure up. Anytime you change the drive train you'll have to resize your drivelines.
If I remember right the J-10 T-18 have the long input shaft & the bigger bellhousing? You can save some space with the short shaft & smaller bellhousing.

If you just want to know if a T-18 will fit in a CJ-5 .... yea it does, seen lots of them .... with some very short rear drive shafts.

Rockin On

Re: t-18 length question

the particular transmission that i have has a 1 inch adapter between the trans, and bellhousing, where most of the j-truck ones have a 6 inch or so adapter. The rear driveshaft should be roughly 20 inches long.

Re: t-18 length question

What you also need to look out fore is how far it will push the shifter back.
Measure from the front of the bellhousing on the T-18 to the front of your tranny. and your current transmission and see how much differance there is. to decide if your shifter will be pushed back too far.
Advanced adapter catalog should be able to give you most of the information you are looking for.And if you call them and explain your situation, they may be able to help alot more.

Ok sounds like you have a non Jeep bell housing?
J-10 with a 6 inch adapter????? Huh???
You sure you have a T-18?? Only available '77-'79 with 6 cylinder motors, '70-'83 with v-8's.
What motor are you mating this up too?

Re: t-18 length question

Jeep used the T-18 in FSJ's from sometime in the 60's or early 70's to the 80's. I thought all the early ones had a long adaptor between the transmission and belhousing, some thing like 6 of 8". Also check the length of the input shaft as they may have used a shorter adaptor and a longer Bellhousing. Also make sure you do not have a T98 as these look simmilar to T-18's and have simmilar strength but use shorter lived bearings/bushings.

Re: t-18 length question

It is going behind a 360, and was originally behind a 258 in a 79 j10. The bellhousing looks just like the one that was on my t150.

Re: t-18 length question

dang.. i thought all the fullsize jeeps had that 6" adapter... mmm.. i would think that the T18 was not stock in that truck you pulled it from.. and the 1" spacer is used with the T150 bellhousing.. another giveaway that the tranny wasn't stock in that truck.. will it work in your cj5.. yes.. sure will.. you are lucky with that short input...
