on my suncoast 3, ever since i got it back from the shop the 3-4 shift if your 75% throttle or more it acts like you limp it and then when you let out it shifts and keeps going. whats the deal here its a real pain.
Did you reset your tap cells?? You might be experiencing some lazy TCM shifting, you need to train you TCM on how to handle the modded tranny, the easiest way to do this is to have the tap cells reset with a Tech II.
