Heavy Duty 42re

Does anyone have experience with a high performance built 42re. I am in need or a rebuild but am disappointed that my factory built trany only lasting 85k and even when working well would “slide” in to gears rater than give nice firm shifts. Granted I don’t know the maintenance of the first 50k but it seems that the 42re is the week link in the drive train. This is going into a stock rig but It seems other stock jeeps are needing rebuilds around 100k as well, so I’m thinking I don’t want to be dumping another trany in it in 3yrs

I have had a local shop quote me around 2300 for a “full rebuild.” I then started looking around the net and found a few high performance builders building racing transmissions. Does any one have experience with either of these two builders?

Thanks for the feed back and other ideas.

You don't need a high-performance rebuild, you just need to make sure that it get rebuilt with quality parts. There are really only a few parts that need to be upgraded in the trans to beef it up.

I swamped my Jeep and I got water in the tranny and had the local aamco rebuilt it and for an extra $85 I bought an aftermarket shift kit and had them install it. Now it shifts better then new and the shifts are firm.

Agreed.... add a shift kit with the rebuild. I checked locally before I did it myself and everyone was around $1200-1600 unless you pulled the tranny yourself. Then the price went to $850 range. Of course I'm hard headed, so when I did mine myself, I spent just under $450 with a new torque converter and shift kit.

I also bought a transmission specific manual that helped tremendously... It's faily straight forward. Take your time. You'll do great!

It's still running.

I recently swamped my tranny too - it was like draining chocolate milk out of it when the pan came down - the tranny was rebuilt with Heavy duty bands and a shift kit. The also plugged the stupid breather behind the torque converter and plumbed one up on top. $2800 over all at Aamco - shifts like a mustang now - its pretty crazy! They also added a heavy duty tranny cooler.

Thanks for all the feedback. Then jeep goes in for a tranny on Tuesday. I had local quotes from $1600-3000 with most shops wanting around $2000 for the rebuild. I was just thinking for a few hundred more I could get a custom built high performance built trany that should out last the jeep. I’m sure hopping the shop I chose does a better job than jeep did.

I asked about using a shift kit and they said it is part of their standard rebuild on a 42re
