What causes no take off power at all

Hello, does the engine rev high with the pedal to the floor as you've stated? Or does the engine have no engine speed either? If there is no engine free revving with full throttle, then there must be an air intake or exhaust restriction somewhere. If there is free revving of the engine with no movement, suspect a transmission engagement issue. Hands on testing is needed. www.repairpal.com/repair-shops
