Can a throttle positioning sensor cause a transmission not to work? And how often is a bad transmission misdiagnosed because of a bad sensor?

TPS will not cause trans not to function as for misdiagnosed maybe Gubber would in Mayberry but with scanners, pressure tests ect can't see that happening

Thanks, I should have told you that the trans does work in 1st, 2nd and rev. But I can not get over 25 mph. I just thought the TPS might not be telling the computer or solenoid to shift. Could that be?
