I have a 97 Jeep Grand Cherokee 4 x 4 limited with an auto tranny. I want to change the transmission filter. The manual I have says to adjust the bands while I have the pan off. The problem is the manual lists 5 diff auto tranny models. I looked at the id stamped in the side of my tranny and I do see any numbers close to the ones in the manual. the manual says there is a 42RE, 42RH, 44RE, 46RH and a 46RE and it lists all with the same torque values but different back off turn numbers once you reach that value. How can I determine which one I have?????

bill k: Trans. band adjustments should be left for professionals, IMO. And, I'm NOT one. With that said, this is what I found:
According to what I found, it narrows it down to three possiblities; 42RE, 44RE, and 46RE. All three of these use the same spec; Kickdown: (with adapter) 47-50 inch lbs. (w/o adapter) 72 inch lbs.
Low/reverse: 72 inch lbs.
Again, I'd strongly advise having a transmission shop do these adjustments for you, assuming they are even needed. Band adjustment is critical.

Right out of the HAYNES MANUAL it says to adjust the bands when you change the filter, all adjustments are to 72 inch pounds, the diff is how far to back off the adjustemnt screw after you reach 72 inch pounds, the 42 RE says back off 3 5/8 turns, the 44 RE back off 2 1/4 turns, the 46 RE back off 2 7/8 turns. Sounds simple enough to me, the issue is to determine which tranny I have. The car has over 100K miles and when it sits for a day or two and I put it in gear it takes a few seconds before anything happens, then it moves slower then normal while the engine is reving up for another few seconds and then all is normal. I guess the fluid is crap and the bands must have some wear. and any tranny shop in S Florida is suspect. I took it to a jeep dealer a few years ago to have the fluid changed and they said the tranny needed an overhaul and I would be lucky if it got me home, that was about 30k miles ago.

Bill; I know that CarQuest now carries ATF+4 now. Both my Dodges require it, too. It's cheaper than Mopar brand.

Depending on which transmission you have, the specs call for DexII or ATF+3. You will be safe, either way, using ATF+4. Not worth taking a chance.

The 'we feel comfortable' part is what bothers me. Valvoline makes a trans. fluid called "MaxLife" that is 'supposed' to cover most all applications and they guarantee it, but I wouldn't put it in my vehicles. We don't do that many trans. flushes, but when it calls for special fluids, other than Mercon/Dexron III, to limit liability, we use what the manufacturer recommends. Can you spell paranoid? LOL. Personally, I've never had an automatic trans. fail. Shouldn't have said that. Darn. Regular maintenance is the key.
