Transmission... Adjustment, maintenence, or impending doom?
The tranny in my 300CD is acting funky.
Under most normal circumstances, it drives and shifts perfectly, and always perfectly when the tranny is still cold.
Once it's warmed up, it does some other things. Under most normal, easy driving, it's fine. Under harder acceleration, it shifts fine until the last gear. The 3-4 shift is strange. It almost acts like it's two shifts. If you gently let up on the throttle, it drops right into gear perfectly fine.
The kickdowns work fairly normally too, although I dont kick it down by matting the pedal very often. But sometimes, if I do, it almost slips out of gear for a sec, revs up very quickly, and then falls into gear. The fluid is in excellent condition, it looks like it just came out of the bottle. This is because it used to leak a little at the cooler. The leak turned out to be just a loose fitting. I tightened it and topped it off, and it has not lost any fluid since. I never let it get too low even when it was leaking.
The shifts seem to be timed correctly, but I'm not 100% certain of that either. They seem like they might be a nudge late.
Any suggestions would be helpful.
