I know this is a bit of a crazy idea, but I am wondering if it is possible to put the transfer case from a FT4wd vehicle on a tranny that is D/R 4WD. I have three reasons for doing so, 1) RX's are rare here in the east, 2) I don't want the RX gearing ratios (too high and steep), and 3) I can get a D/R tranny and a FT4WD tranny cheap. Any thoughts? In particular, is the overall length different (would I need a different rear axle)??

I know for sure that what you are looking to do is not a simple bolt on. The shaft that sends power to the transfercase is different between the two and you can't simply swap the shafts because the pinion gear for the front diff; is machined out of the shaft.

the RX ratios are the same as any other 4WD in hi range....its just the reduction in lo is not as 'lo' as the regular D/R.

Thanks GLCraigGT - that's what I needed to know. I knew I would have to swap that shaft, but I didn't know if the drive gear was the same.

WJM - there are two sets of gear ratios, one for turbos and one for non-turbos (look in the 1989 FSM - I just don't have the part on transmission internals.) The turbo cars have a much steeper 1st gear b/c of the 3.7 diff. All the other gears are lower, and I do NEED the low range! I sometimes use the car to pull/drag stuff that are nearly as heavy as it is!

I might still grab both trannys to see what I can come up with. Good summer project - I'm too busy now!

Hmmmm......i guess I'd just stick with the regular D/R then.

 

I like my FT4WD D/R RX box just fine.

Yeah, you have the power, so you do not need the lower 1st gear!!

Thanks anyway!
