2000 TJ Transmission Problem

Just bought a 2000 TJ with 95k miles, auto trans. Changed trans filter and fluid because the previous owner did not know if or when it was last changed. Old fluid did not look too bad. Got it all back together. Put in 4 qts ATF+4. Drove it around town for a few hrs, the rest of the day. Went to a friends, and parked it outside, running in park. Went to leave, and would barely move when put into any of the gears. Had to rev it up to get it to do anything. Acted like it was low on fluid. Double checked the fluid level, and looked for leaks. Fluid was fine, no leaks. Put it in neutral, and started hearing some whining. Shut it off, and went to bed. Tried it again this morning, and same thing. Talked to a transmission shop. They said it sounds like the pump went out. Does that just all of a sudden go out while not moving??? Could it be something real simple Im just not aware of. If it is the pump, how difficult of a repair is it? I am pretty good in the garage, and have worked on vehicle all my life, just not automatic transmissions. I have heard these (32rh) are pretty simple transmissions. I have never owned an auto jeep. But after reading, I they are pretty reliable, when maintained, and lots of fun. I am about to drop the pan again, and make sure the filter didnt clog. Also just gonna double check everything on the underside........AND install a drain plug while the pan is off! Any input on what the problem could be, will be greatly appreciated.

How are you checking the fluid level. Need to crank, run thru all the gears, then put in neutral and check with the motor running.

Ok. dropped the pan again, and WOW! The filter was totally clogged. Another filter and fluid change......Up and running. Going to do at least one more change on it to see how this filter is. Then go from there

I hate to say it but sounds like the tranny shop may be right about the front pump. It will cost you about 15 quarts of fluid but you could try a full flush. I water logged mine one time and drove it home about 60 or 70 miles sounding like a bad power steering pump. Flushed it and it has been OK since. That was about 2 1/2 years and 50K miles ago.

Just thinking out loud, to flush the tranny, you have to take the cooler line loose on the passenger side of the radiator. I put about a 12" piece of fuel line or cooler hose on the nipple at the radiator and point down into a five gallon bucket. Might be worth trying and just see what kind of flow you have through the cooler. Just let it run for a few seconds, maybe 5 or 10. This might give you an indication of the pump pressure. I always have my son start mine in neutral when I do this and I watch the flow. Pump does not run in park. Before you spend more money on fluid, my be worth a try.
