Something is not breathing right, from plugged air filter or pluggeg exhaust and this includes the catalytic, Here is what gets me when you get to 40MPH then it drives normal, you are describing a tranmission problem, check the transmission fluid condition if it is brownish or even blackish you truly have a transmission problem.
