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?

More likely Vehicle Speed Sensor trans is self diagnostic codes can be retrived from computer to aid in diagnosis
