Ok so i have an 04 lj, and i was having the usually heat tranny slip problem, and i dont get it anymore so thats not the problem but it would start to slip for a second and kind of buck then go when it was cold, i replaced the fluid and filter and filled it up to what everyone told me they manual said how much, it worked fine for a weak and started slipping again, so i added some tranny stabilxer i found at autozone and it worked fine for 6 months not a single buck nor slip well its back and im not quite sure what to do to get rid of my problem. Any suggestions?
drop the pan. if you see gold speckles in the fluid and have lots of metal shaving stuck to the magnet you need to rebuild the tranny. Note the 42RLE's don't seem to last long. Mine was dead at 50k, yet shifted fine as I drove it into the stealership, with two disintegrated snap rings and half a clutch pack destroyed.
how many miles are on it? did you use Mopar ATF+4?
ok so if im assuming id have to shell out 2000 on a tranny new or rebuilt if i swaped it out with a manual what would that be and would i need anything else other then the computer?
theres a thread going on right now where a guy is swapping a NSG370 into a 2004 LJ...search it.
basically going to a manual is even more expensive, and a crapload of work. i looked into it pretty extensive...just decided to keep the 42RLE...and have somebody rebuild it stronger & better the 2nd time around.
Swapping anything will be a pain, IMO the only decent swap is AW4, but even that will be expensive and a lot of work. Mine slips too when it is really cold out it has to do with it's warm up cycle, it slips more so the transmission will warm up faster. If it is doing it when it is warm you have a problem.
