I replaced my dmf last week after it failed. Since then, my transmission will not go into 5th gear all the time. After a right turn that is hard enough to put some lateral force on the car it will not shift into 5th gear. This condition continues until I make a left turn causing enough lateral force or if I rev it up in 4th gear until I hit about 60mph it usually will shift into 5th after that. Also, I noticed that my shifter lock pin doesn't seem to do anything. When I engage the pin the transmission can still shift. Not sure if this could be a cause of the 5th gear problem. I read in another forum about someone having 5th gear problems and it turned out to be low fluid level. So this last weekend I changed the fluid, which was a little low, but it didn't fix the problem. I also pulled the side cover to inspect the 5th gear but couldn't see any problems. Has anyone ever heard of anything like this? I'm trying to figure out what to expect before I pull the tranny off again and take it apart.
