New to the board-- hope someone can point me in the right direction. When I start truck up it idles fine. When I take off the engine will go to 2000 rpm+ but the truck only will get up to 20 mph. After about 3 minutes with my foot to the floor it takes off like big time!! I have stopped, shut truck off and restarted and it does it but not as bad. Also, driving down the road at 52-60 mph I get dead pedal when in overdrive. I can kick it down and it takes right off. Goes back into od same thing happens. Any help would be appreciated.
