Every now and then when I floor my '85 300D, it downshifts but then refuses to upshift. It was an intermittent problem and I thought since mine was a CA emissions model I thought it was something in the egr computer. I even had a switch wired into the "secret" fuse located behind the glove box so everytime the tranny would stick, I could just switch it off and it would shift fine. Then I read somewhere in a post that there was a kickdown switch under the accelerator pedal. I never knew there was that there even was a switch like it. I had the problem again recently and this time I remembered to check out this switch. It indeed was sticking on occasion. So...if you ever have a problem like it won't shift, check out the switch. It may save you an expensive trip to a transmission mechanic.
