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..
