Vibration when accelerating
My '88 300SE has a slight vibration when accelerating from a complete stop. It only seems to happen a certain speed then goes away. It only occurs in 2nd gear and does not happen if I kick it down to 1st when taking off from a stop. There is no vibration in any other gear under any condition.
My transmission was rebuilt at 140K and I recently replaced my engine mounts (exhaust was hitting frame on hard acceleration). I've also replaced the front flex disc. Could it be a bad transmission mount??
Thanks in advance for the advice!!
