jeep yj trans swap

[tennessee_4x4_man]

i just got a 94 yj 4.0 with i guess a ax15 5 speed i would like to know how big a deal is it to swap in a auto from a xj

It depends if you want to shift it manually it not. I swapped one into my Jeep using the RAdesigns Winters shifter and it was cake. I used a Cherokee flexplate, starter, and TC. My swap was on a 4.2. I imagine the swap on a 4.0 would be the same or easier.

If you want it to shift like a normal auto, there's a bit of wiring involved to splice the tcu into the harness.

They use eletric solenoids to do all the up-down shifting.

If you buy a kit from Radesigns, it has a wiring harness that hooks to the trans and switches are built into the shifter.

you have to have a shifter to shift the linkage from Park - R - N - D , then the electronics make it shift gears 1-2-3-4



I had a Toyota with a AW4 from a Cherokee in it, it had 2 shifters. The stock Jeep shifter hooked to the linkage, and then an 4 position electric switch shifter from an arcade game (like Crusin USA) mounted right behind the Jeep shifter to control 1-2-3-4 shifts.

You could shift to R from any gear, and it was fully manual, what ever gear the arcade game shifter was in, is what gear it would start/stay in.

I did mine about this time last year. The RADdesign is worth the cost. Great customer service also. I think it was 4 wires...maybe 3. Anyway, super easy and worth the time.

What condition is the AX15 in?

I may be interested in it if you do the swap

 

[tennessee_4x4_man]

You could also swap in a 3 speed auto... no wiring required

From a YJ/TJ?

(I dont know that Ive ever seen a 6cyl auto YJ? Is that a thing?)

I don't know nuthin about jeep transmissions though haha

muddycreek probably knows more about what you are wanting to do

 

[tennessee_4x4_man]

ok i need muddys number what about runing the tf999 they were stock from 91 to 95 there a 3 speed auto are they simpler to hook up

 

[muddycreek]

The TF999 (Chrysler 32RH) was behind the 2.5 and 4.2 in jeeps

You would need one that was behind the 4.2 block to mate to a 4.0 block

muddy you are the man i just got a trans ans case from a 96 xj one guy said that was a funcky year that had a tcm had to be wired in factroy pcm to make it work i need a little help on how to wire up the 96 xj trans where it will up shift and down shift with the cpu

 

[rpf500]

You really should consider the RAD design shifter. Literally 3 wires to mess with. Check this link, it gives more detail. I was going to use factory wiring also, and I'm glad I didn't. This was simple, clean, easy.
