'Vette 4L60 issue
Will not shift into Reverse. The shifter moves, but the engine free-revs in R.
Shift to Drive and it moves, but doesn't seem to shift correctly... also doesn't seem to want to go into OD.
No signs of leakage at all.
My ideas are internal issues (not knowledgeable enough to be specific), or maybe the shift linkage has become goofed up somehow so it's not in the right position.
Opinions or anything I can do to help diagnose this? I'm afraid to drive it and cause further damage.
