i first had a studder in each shift and a delay from reverse to drive before it would lock into drive. dealer replaced valve body. transmission shifted perfect! best it had ever been, but still had the reverse to drive delay and started leaking fluid. dealer again replaced valve body then it shifted ok but not like the first replacement and the reverse to drive delay still not corrected. i had backed out of a parking garage and when i put car in drive it started to roll down ramp and i almost hit another person walking by behind me before it caught hold.
