Ok, guys, I have read a lot of forums and talked to people about my AW4 tranny. It hesitates going in to reverse when it has warmed up, when it’s cold it does pretty good, maybe a slight hesitation. It seems like it slips from OD to 3rd a lot with regular highway driving shifts out fine. I haven’t had the Jeep long. I unplugged the TCM, unlike I was told it should do it shifted through the gears with it unplugged. It did take an eternity for it to go in reverse though. I checked the TPS (not sure if that has anything to do with reverse) but I checked it. I have my 5v, now I heard the other 2 wires should be ground and .26v, I do have a good ground but the 3rd wire is .9v (no throttle). When I ease down on the throttle it has a good steady climb but stops at 3.9 which from what I read is dead bottom (it should be over 3.9). Leaving work today I taped up my brake switch, I think that fixed my OD to 3rd changing, not for sure, haven’t driven it enough yet to know for sure. I haven’t checked solenoids yet. I’m just confused on why I didn’t have to manually shift it with TCM unplugged. The engine was cold when I did these tests, My TPM my be going bad. I just can’t figure out why it takes so long to shift to reverse. Any help on what else to check please give me advice before I have to drop the tranny. Fluid looks great, I am going to go ahead and change it because I don’t know what the previous owners used.
