97 Wrangler 5 speed to Auto trans swap

I would like to swap my 5 speed to automatic trans. I don't know what is involved to make the change and if want has that info that would be of great help. My 97 Jeep Wrangler is a 6 cyl. and don't what years are interchangeable with my Jeep. Also, if someone has automatic and wants 5 speed maybe we can swap.

Yea, I'm on west coast, in the Riverside area of California. A little far from you. But, thanks anyway.

I did that exact swap on my previous '97 TJ. The easiest swap is the the 32RH which is a bulletproof 3-speed automatic. The 32RH was used in the TJ '97 to '02.

Basically beyond the obvious parts needed, you also need to swap in a new engine computer set up for a '97 TJ 4.0L and automatic transmission so the automatic transmission's lock-up torque converter will work properly. You will also need to install a replacement longer (extended) output shaft seal into the 32RH so it won't leak where the transfer case input shaft seats in the transmission. The t-case intput shaft is too short for the 32RH so the new extended output shaft seal for the transmission fixes that. You can get that extended seal from Teraflex, Advance Adapters, Summit Racing, etc.

All the wiring is already present in your TJ, no need to add or change any wiring. So is the transmission cooler, that is part of the normal radiator that Jeep installs.

Finally, you don't have to remove the clutch pedal if you don't want to. I welded a piece of steel between the brake and clutch pedal so I could use the clutch pedal as a brake pedal for my left foot while rock crawling.

I'd be happy to talk with you on the phone if you run into any snags on anything.
Remember that having a different opinion doesn't also require one to be a jerk when expressing it.

When you have a choice, buy American.

Thanks for the information about the swap. So it sounds like the transfer case input shafts splines match the output spline of the automatic trans. How about the over all length of auto trans and transfer case. Are they the same length as manual trans and transfer case. Because I already installed the slip yoke eliminator on my transfer case. Furthermore, how do we exchange our phone numbers without everyone seeing our phone numbers? Because I have some more questions (like where would be a good place to find these parts) I live in Riverside and it looks like you live in Southern Cal.

Click on the username you want to exchange phone numbers with and send them a private message.
Just because I drive a Jeep doesn't mean I'm going to "wave" back at yours.
