The car will not drive forward or go into reverse. The linkage is intact, I have changed the fluid and filter there was no debris in the pan, the fluid was not a true red maybe a little burned but not smelly.I have disconnected the cooler line the fluid gushes out rapidly. Does anybody know what the problem is or do it yourself test on tranny and or related parts. I don't want to throw money at the wrong thing. All comments and tips are needed. Thanks!
