the tranny shouldn't shift into overdrive until the car is going over 60 mph,sounds like its time for a rebuild.

Well idk cuz it shifts smooth and doesnt slip or anything. Also it shifts into overdrive around 50 55 i meant when im running low rpms by not accerating heavy and hit bout 50 is when the rpms bounce, do u know of anything else it could b? Mayb tranny fluid and filter change, fluid looks good?
