[W126 Coupe] Vibration on acceleration and tranny servicing

[Dick Spellman]

I would recommend changing the fluid including the contents of the torque
converter and filter every 15-20k miles for city driving and maximum 30k for
highway miles.  Vibration associated with drive train, I would inspect the
flex disks and grab hold of the drive axle and see if there is lateral or
vertical play in the center bearing.  Replace whatever is worn.

Regards,

Dick
