is this my converter locking/unlocking?
After my cam install and retune my tranny feels different. Now say when im on the highway going 70mph and get on it some my its like it shifts or something and then goes into 3rd(D)? is this my converter locking/unlocking?? It didnt seem to do that before? All comments are welcome...TIA
yeah ive done this and it changes gears. I wonder why it just started doing this after the cam/tune? Is it in the tune you think? Is this beneficial to me that it locks/unlocks like this? If i were to race from a roll at 60mph would it hurt me? Sorry for all the crazy questions...Thanks guys!
