Hey, so here's my issue on my 95 Explorer 4.0 w/ 4WD. Drove fine today, got home and shifted into reverse and heard a light clunk and nothing. It engages but wont budge, I rev the engine in reverse and it just bogs, even in neutral it binds. D works fine, shifts smooth through gears. In 1st gear has some resistance but it still turns. Lifted the rear end, took of the driveshaft and the rear end spins free by hand, trans still wont turn in reverse. Shifted into neutral and I can spin the transfer case by hand in 1 direction, wont budge in the opposite direction. Removed the transfer case, and it looks good. Problem is in the Trans, had a problem a few years back with a blown torque converter, changed it out and flushed the trans, also changed the filter like twice after the initial torque converter replacement. I don;t think it would be a valve body issue, thinking something internal in the trans. Anyone have any similar issues? Planning on pulling the trans, I was a mechanic for 15+ years but never really got into the transmission side too much. Not sure if I should just pull it and take it to a trans shop for a rebuild or try and figure it out myself. Thoughts???
