I've got a '93 300e, 92k m. with auto trans. It does not feel like there is a smooth transition between the gears, especially the shift to 4th. When I drive my Cherokee with same miles, I cannot even feel the shifts. The trans expert that rebuilt the tranny said its Clutch Shudder and put in an additive into tranny oil to lube the clutch. Slight change in upshifts but still a noticeable shudder.
Any hints on what it could be?
