on the 88 300ce, i can engage reverse only from "P"ark; when i try to engage by moving the selector up from "D"rive, its as if the car is in neutral, and the selector often doesn't always stay in reverse & slides down to neutral. The tranny shifts fine thru the gears in drive. Car was just bought & fluid was clean & didn't smell burnt. No leaks. I've searched but didn't find anything like this. I also have rough start/idle, which, based on what I've learned from this board, I think comes from a rip I found at the end of the hose going from the idle control valve to the distributor. That i will replace. Would this have anything to do w/ the shifting problem? Thoughts? Thanks
