I have a 96 xj with the 4.0 liter and the aw4 trans. About a month and a half ago i was driving home and lost all but first and reverse gears. I was able to limp it home. The fluid was full and wasnt burned at all. So I had a jy trans put in by a friend of mine that owns a repiar shop. I was really excited to get it back and be able to drive it again. But there was another issue. While cruising on the hwy about 65-70mph, the rpms would stay around 2200 rpms then if you would slightly release the gas pedal the rpms would jump up to bout 2800. Then it would jump out of overdrive complety and in a few minutes drop right back in to od and start the cycle over again. Before i condomed the trans i wanted to make sure everything else was good. I changed the tps sensor and then changed the trans control module, still had the same concern. So I took it back to my friend and he put in another trans. I thought all was well untill about 20min into the drive it started doing the same thing all over. I even changed the fluid out completly this time. And now on my way home tonight, when the trans is in drive and its warm it is very sluggish to accelerate, almost like it is slipping. If you put it into 1-2 it takes off fine. I am at my witts end here and dont know what the heck is going on. Is it possible that i got 2 bad transmissions? All I know is that before the original trans died i had no problems what so ever. Any suggestions?
