Transmission will not shift when pulling load

35

Asked by Apr 10, 2011 at 01:29 PM about the 2002 Ford F-250 Super Duty

Question type: Maintenance & Repair

I have a 2002 Ford F-250 2WD with 7.3 Liter powerstroke and automatic transmission.  When I pull my camper or have a load behind it it will not shift into overdrive; I have to pump the fuel pedal to get it to shift.  I have tried putting a new shift kit in the transmission but this did not help.  It shifts fine when not pulling a trailer or load.  Any thoughts on what the porblem may be.

ya need some programing with a flash tuner

their may not be a problem,towing that much weight might just be to much to go into OD.overdrive is mainly for cruiseing at highway speeds,not ment for towing,that is when you want it to stay in drive so it wont overheat the tranny and burn it up.think their is a sensor on tranny just for this.
