Transmission Upshifting Prematurely?

[Annu Kumar]

It just started to happen recently:dontknow: Even when I floor it the tranny Upshifts too soon at like 4500 RPm to 4800 rpm. It doesn't redline anymore like it used to at 6K. Its a Bummer. any thoughts??

Mine hasn't done that but it jumps back and forth between 1st and 2nd at light throttle on takeoff. The dealer said it is a valve body problem. I am guessing a band thing. It doesn't do it when the selector is in 1st or second, only in Drive.

yeah something to do with the throttle pressure cable... either it fell off or it needs adjusted
