96 SL500 with 97k on it, runs perfectly until earlier this week.
Symptoms are very rough downshifting. Upshifting seems to be perfectly OK, downshifting if braking to a stop seems to be ok. No chatter or vibration, runs smooth.
If I accelerate about half throttle or more and it downshifts then I get about a second pause, with rising RPM's like its slipping, then it will slam into gear, rear tires will spin a bit, etc.
I am hoping its a valve body or something electrical, would hate to have the tranny go. I did do a transmission filter and fluid at 60k at the dealer.
Anyone have any idea?
