Slight surging between 65 & 70 mph - overdrive shifting in and out?
I get up to 65mph on the highway and try to slightly accelerate and between 65 & 70 mph I feel the truck surging like it's going in and out of overdrive. The transmission fluid was recently changed and it did the same thing before. It seems to be fine when it gets over 70mph. I can get it up to...- Sunbelt56
