I have a 2002 Jeep Grand Cherokee and the transmission failed Friday. It's had minor transmission issues since March. I got a pan leak fixed. Then It began to slip out of gear and rev as if it were in neutral in traffic circles. It would also shift quite rough at times, but not too bad though. Delayed engagement into reverse too. I had a fluid flush done approximately 800 miles ago and a band adjustment. Everything has been fine since then except for first gear surging every morning. I would let the car warm up 3-5 minutes on the cold days (like <30°F). Still surged. I clean the undercarriage of my car every week to get all the road salt off (I live in Ohio). When I cleaned it Friday, it was about 21°F , I merged onto the freeway five minutes after. Oddly enough, immediately after washing there was a grinding/whining noise whenever I was on the throttle. When I arrived at my destination a few miles later, it would not stay in gear going about 40 mph, and it would slip, jerk and grind. It would not move in reverse either; it would just rev with a nasty whining/grinding noise when I tried giving it some gas. Could water have frozen and damaged the outside components of the transmission? Or could I have gotten water inside the transmission somehow when I sprayed? Iv'e sprayed the undercarriage many times in the past and I have had no issues. I wouldn't think it could freeze that fast though with all the warm exhaust components and warm transmission oil pan, could it? Or would it be safe to say that because there have been issues off and on recently it finally just gave out today, having nothing to do with the undercarriage wash and the ice?

I had asked about a leak about a month ago and after I got the fluid changed there was no leak out of the front of the unit so I don't know. But I'm pretty sure at this point I'm going to need a new transmission.

Thanks for taking your time to read this long post.

yea, those trannys are junk and for whatever reason yours is now shot. My advice, get a dealer OEM rebuilt tranny with a real guarantee
