Torque converter?

I have signs and symptoms for a torque converter and a throttle positioning sensor. What are some ways of testing to narrow which part is going out?

Tell us more about these symptoms. Are you getting any codes?

I was told to accelerate until I feel the shutter, which is at 40 mph, and set cruise control for 37 mph and accelerate using cruise control and if it doesn't shutter than its not the throttle positioning sensor. Well I tried it and it still shuttered but I'm not experiencing any slipping so I'm still convinced it is the throttle positioning sensor

I'm gonna just replace it and see what happens. If it fixes it awesome if not at least it's a new part and it should be good for a long time

How many miles on you truck? Are you aware of the common problem with the '01 transmission and the "diode clutch"? May be your issue if it has not been rebuilt already.

I'm currently sitting at 191,100 miles. This would be the first time I've heard about the clutch diode. What are the signs of a bad clutch diode?

The symptom of a failed mechanical diode one way clutch is no 1-2 shift, or the shift will only happen at very high RPM after you lift off the accelerator pedal.

I seem to have recently had a shutter start at cruising speed any time you are cruising at a steady speed. If you let off the gas it is smooth as silk but anytime you are cruising at a steady speed it has a kinda shutter to it. Cruise or no cruise

Look for a problem with an injector.
