More bad new: I climbed under the car today and discovered that whatever the problem is, it is definitely NOT a shift-linkage problem. The linkage is still in perfect adjustment, and the detents on the floor shifter match perfectly, the detents I feel in the manual shifter arm, (where it comes out of the transmission.)
Whatever is broke, it is broken INSIDE the transmission. No matter what position you put the manual selector in. the car wants to move forward if the engine is running. That includes PARK, REVERSE, and NEUTRAL. The is no way to make the car back up, and the PARK posititon acts just like all the rest... forward movement. I have to chock the wheels to keep it from rolling away.
If it's not one thing, it's something else.:banghead:
