280ce Won't Upshift
 

Newbie here, first post. I don't have a Benz yet. I am a recovering Jaguar-holic. I am looking at a 81 280ce on Craiglist. The owner says the trans won't upshift past 2nd gear until the car warms up for 20 minutes. She says the trans was replaced about a year ago. Is there something simple that might be causing this? Thanks

Is it a USA or "euro" car?
They have different transmissions!
IF it is a USA version...could be as simple as a loose nut on the output flange.

I believe it is USA spec. How would the loose output flange keep it from upshifting?
