Transmission Rebuild?

I was wondering if anyone has any experience with rebuilding a 42RE Automatic Transmission.. Mainly wondering if it's something worth considering, or is it really involved with lots of special tools and techniques required?? I have a í99 Jeep Grand Cherokee 4.0L --my tranny is on itís way out and Iím debating on whether or not to attempt the rebuild myself.. Iíve swapped engines on the jeep and try to do most work on the Jeep myself.. But not too sure about a transmission rebuild.. I ordered a transmission rebuild manual thatís supposed to illustrate the whole process, so Iíll see how involved it looks from that.. But any feedback on how ďcomplicatedĒ it may be would be appreciated.. Essentially itís a matter of about $1800 for a rebuild at a shop or a rebuild kit for under $200..

There seems to be various transmission rebuild kits available --just did some quick searches to get a ball park idea on pricing and found most to be less than $200..

Ebay has a kit for $130:
42RE Super Rebuild Kit (Ebay)

and I came across a high performance kit at IPT Performance Transmissions for $375:

Also check www.Deantransmission.com They sell high quality mostly OEM overhaul kits. Also you will want to replace the torque converter as most of the junk sits in there and you don't want your nice freshly rebuilt transmission contaminated with that stuff. There are no tricks to overhauling it, some special tools to disassemble the overdrive unit, which you probably don't need to do anyways. Cleanliness, cleanliness, cleanliness is all I can say. No dirt and don't use shop rags to clean anything (they leave fibers behind)

I heard it was easier to rebuild a 42RE than a GM700r4, and the 700 is freakin easy....Brandon is right, cleanliness is a must!!!

I found this on Ebay marked really wrong. I am sure someone here will find it useful.

I appreciate the feedback ..Thanks, I'm definitely leaning towards rebuilding myself ..and if I do, I'll remember to keep "cleanliness" in mind...

I got a 42re sitting outside right now you could always rebuild for fun. if you want practice.

I bought an ATSG 42re service manual from ebay awhile back, I think it was like $12.

It might get rebuilt one day if I get around to it

Thanks for the offer for some practice.. was actually considering possibly picking up a junk yard tranny for "practice" and also minimize vehicle down time in being able to just do a swap.. but I'll have to see if I can find one locally for cheap..

also ordered the same manual from Ebay, waiting for it to come in to see exactly what's involved in the rebuild..

I keep saying im going to attempt to rebuild it, but in all reality coming up the spare money for the rebuild kit and actually doing it will most likely never happen..

Harbor frieght has a decent set of snap ring pliers if you dont have a set..
