Tv cable was adjusted by me and a professional transmission place neither made the difference. I heard the transmission is controlled by the computer is there a way to get around this? and anything else could cause this?
what did you do to the engine to give it more power? did you swap the toque converter at the same time to match the cam if you put another cam in? what rear gears are in the diff?
more often than not, this is a result of a big cam installed and not also installing a new higher stall converter to match the cam.
also, if the car was fine before the work was done, then odds are that the problem is related to the work done.
on the shifting of the car, if its shifting late and hard and you have no passing gear, if what i mentioned above is not related to whats going on with the trans, then it just doesnt have enough tv pressure set in the cable, or it could be a combination of both.
