1978 450SL - Vibrations after upshifting
Hello,
When I accelerate in my 1978 450SL, I hear and feel vibrations after the transmission upshifts. The shifts themselves seem smooth, but then I get the vibrations for about a second and a half. The issue is worse when accelerating harder - like getting on the freeway.
I'm thinking maybe it's the transmission mounts or motor mounts. Does that sound right? I haven't been under there yet to check them out.

I was told the transmission mounts and flex discs are fine and they couldn't tell me more without checking out the transmission. I think maybe I need a second opinion. I really want it to be the mounts.
