My transmission fluid is fine. It's not a shudder. I know those from past Benzes.
It's more a sense of fluttering.....a loss of power. More liukely a vacuum and/or fuel/air mix thing. Or both, since I've messed with those items. Bad boy!!!
No fluid leaks.
But if you will recall, that strut that runs connected to rear of a throttle roller linkage down towards tranny. I've not dealt with that. It's connected, but moves around too easily.
Might still be that?
