Fryedaddy Posted August 2, 2019 Posted August 2, 2019 I’ve been driving my MJ a bit lately. I’ve driven it 2hrs 110miles on way and back. Recently (before trip) I noticed it will slip when I put it in reverse. It has 180k on it. Weird because it will go in reverse, engrave then while backing up slip then catch after a few secs. I’ve driven it a total of 3-4K since getting back on road. Fluid is good but I’m not sure on level. Can’t determine if trans stick is factory or not. Shld I drain and check amount or trust trans stick? Any other suggestions?
krustyballer16 Posted August 2, 2019 Posted August 2, 2019 I have the same issue, I think. In my 01 cherokee. Reverse died after wheeling one day. Put it in reverse and barely moves with throttle.I havent had time to investigate it at all other than driving it into my driveway off my trailer. All forward gears are fineSent from my SM-G973U using Tapatalk
cruiser54 Posted August 3, 2019 Posted August 3, 2019 CHECK THE LEVEL!!!!!!!!!!!!!!!!!!!!!!!!!!!! Dex/Merc ATF. .Easily drained and refilled. Buy a gallon. Pull the plug. drain. Install plug and refill. Adjust the throttle valve cable.

Install plug and refill. Adjust the throttle valve cable. Fluid level was my first guess. Even though I'd think itd slip in every gear...but I checked and its filled right and i changed fluid not too long ago (less than 1000 miles) Guess i should mention mine went out after rocking back and forth full throttle in a mud hole...Sent from my SM-G973U using Tapatalk
75sv1 Posted August 3, 2019 Posted August 3, 2019 I thought reverse was a direct manual gear. I could be wrong. I'd unplug the trans control unit. Then see if it has the same problem. You will have to manually shift. Also, no down shift on the trans. So will have to brake to reduce speeds.
krustyballer16 Posted August 3, 2019 Posted August 3, 2019 Just because I'm a helpful problem solver. Would be an option!Sent from my SM-G973U using Tapatalk

Fryedaddy Posted August 16, 2019 Author Posted August 16, 2019 Just now realized you all responded, thank you! My fluid level appears to be fine and the fluid is brite red still. Doesn't smell funny either. I'll try adjusting the TV cable and replace fluids as well

krustyballer16 Posted November 6, 2019 Posted November 6, 2019 Did this issue ever get fixed? I still havent messed with mine and havent come across a fix. Everywhere I've read says I shouldnt have 1st gear either but I do. I can put it down in 1st and power brake it and do burnouts. But can't power brake in reverse. Or give any throttle in reverse without it slipping...fluid looks a little old but not really burnt...Sent from my SM-G973U using Tapatalk
