Newbie w/ transmission woes

Hello folks, I bought a 1998 Jeep TJ, to build to play in the mountains of Southwest Colorado.... It is a 4.0L w/ a manual transmission, the guy I bought it from had a good transmission he threw in with the purchase.

I put the new transmission in, everything was identical and fit great...until I got to the skid plate part.. turns out the bolt pattern where the transfer case connects is different, not by much but the transfer case sits down and do the left a bit more, which causes my front driveshaft to rub on the skid plate.

I took the housing which has the bolt pattern for the transfer case off and my thought is to try to fit it on the good transmission, the bolt patterns all look the same, but I figured i'd ask if anyone knows before I do alot of work for nothing.

thanks!

it sounds like the trans might be from a 03-06 in that case you may have to use a skid plate from a 03-06

someone with more experience is going to have to confirm and correct me if im wrong, now may also be a good time for a tummy tuck

never mind i see what you were getting at in the OP. I cant think of any reason why that would not work although i have never tried it

thanks cbush1885, just purchasing a new skid plate would be awesome, I am really dreading changing the housing where the transfer case bolts to the transmission, but if it will work I will do it.

97-02 and 03-06 use different transmission mounts, and a different t-case skid bolt pattern.

you must have a late model trans, trying to put it into an early model t-case skid. you can't change the t-case skid because the bolt pattern is different. you'll either need to get an early model transmission, or fabricate/modify a t-case skid mount that adapts your current transmission to your current skid.

Thanks UnlimitedLJ04, You must be right on the late model/early model transmission.

Both of the transmissions are filthy, is there any marking on the actual transmission what will tell me the model?

Anyone have experience with replacing the housing on the transmission that the transfer case bolts too?

Wanted to update everyone to my solution. I ended up making a template from my old transmission output shaft casing. and drilling new holes in the new AX15. Turns out the AX15 transmission was out of a Jeep Cherokee, which caused it to be slanted about 10 -13 degrees to the left, i had to end up using my old shift tower and shifter.

Using XJ tranny in TJ or YJ requires reclock of holes where transfer case mounts auto or standard both require a reclock
see links


Redrilling the output housing
Renix AW-4 Transmission Swap to a YJ - 4
