Hi. I just bought a F-250 Super Duty Crew Cab 4x4 with a 5.8L. Problem is that when truck goes into overdrive it starts to surge. truck also does this at 25-30 mph through samll towns in the area when your trying to maintain certain speed.
Hauling a empty 8x20 trailer makes it worse. Any idea's. carfax said vehicle was returned to Ford a lot for scheduled maintenance, oil changes, ect like every 6 -8 months. No report of surging that I saw.
Thanks- Joe
