My 2000 Nissan Quest suddenly one day seemed to have transmission trouble so I drove it very slowly about 6 miles or so at 15mph to a transmission repair shop. It came back with a T.P.S. code for the Throttle Position Sensor. They charged me almost $1900 and gave me the car back driving the EXACT SAME WAY. Then my mechanic (doesn't do transmission work so he didn't see it first) fixed the initial code- Throttle Position Sensor in about an hour for $267 and said the transmission shop should never have repaired the transmission without first replacing the TPS because the transmission symptoms might have gone away. Is this true?
