Good Day!
I am a new to the Jeep community and off-roading as a whole. I took my 1997 4.0 Sport TJ mudding a few times this summer threw some deep holes with great success. However this last time I went the mud was super sticky almost like clay. Got stuck in the 1st hole of the day, mud was up to the bottom of the doors. So I tried rocking out, going from drive to reverse and back again. After a few rocks managed to reverse out of the hole. Right after getting out we went to head to the next hole, Put the jeep in drive and tried to get up to speed, but it stayed in what sounds like 1st gear and wont upshift at all. There feels to be almost no power in Drive. I have a 32RH 3 Speed Automatic Trans, so I have P,R,N,D,2,1. So my Park, Reverse, Neutral, and Drive engage just fine but when I put it into 1 or 2 it doesn't feel like the gears engage, the linkage moves for all of them but the jeep doesn't go anywhere and the rpm's still go up. In drive I can achieve a max speed of 30KPH/19MPH and my rpms are around 5000RPM. Before I usually could do 50KPH/31MPH just in 1st at 3000RPM.
The tranny doesn't smell or make noises.
This is what I have tried so far....
Vigorous wash to get mud out from underneath.
Transmission Fluid is above the minimum line. (checked running in Neutral)
Transmission Fluid is Clean with no visible shavings or particles.
I have checked the linkage and it is still connected and all 6 options move.
Disconnected the battery for 30mins and put it back on, in hopes to reset the computer.
(Battery has sense died completely and wont keep a charge)
Used a basic OBDII reader (not a transmission one) No codes.
The only thing wrong prior to this last trip was I started to have over heating issues and low oil pressure. I had thought I diagnosed those issues but after developing this shifting issue it overheated 3 times on the drive limping it home at 30KPH/19MPH.
Any advise or information on what I should do next, as I am wanting to hopefully do this myself that would be amazing!
Thanks!
