My 7.4L has a 4 speed auto trans, it drops down from 4th to 3rd.

Asked by Nov 11, 2014 at 07:18 PM about the 2000 Chevrolet C/K 3500 Reg. Cab 2WD

Question type: Maintenance & Repair

It will drop down to 3rd after about 10-15 minutes running down the freeway, from any speed. It will not upshift back to 4th. If you pull over & turn off engine for a few minutes, it will shift normally until it down shifts again to 3rd.
I had the transmission rebuilt & it still does it. HELP !
