tranny shifting 1-4 way to fast, Help?

[boosted87]

Can anyone tell me as to why my tranny is shifting is so fast. Its shifting from 1st to 4th within a couple hundred yards at normal take off, and when I try and push down on the throttle to get it to down shift a little, it snaps hard down and sounds horrible. At WOT take off it shifts fine. It was doing this before I had the tranny rebuilt and now that its rebuilt its still doing it. Any help would be greatly appreciated. I'm at my wits end with this! Thanks again!

Unplug your tcc solenoid and report back.I had this same problem recently and the tcc was the cause.HTH

I had an early shift pattern and found the throttle valve cable bracket loose. I tightened the bracket then readjusted it and now it shifts better then it ever has . Maybe it will help?
