I have a 190 E a 1989 that will slip when reverse, all the forward gears work find. When it first started it would only go in one speed in reverse, then it would not back up hill. Now I have to let it warm up then build up pressure in the forward gears to go in reverse. I have tried Lucas stop leak it seems to help for awhile, then it returns. I had the fluid and filter change no difference. I need help to find whats wrong. I like this car and don't want to sell it or set it aside.

Try posting this in the Tech help forum
