Accepted Answer

Hello and welcome to justanswer.com

 

DTC P740 is for the torque converter clutch. There was a service bulletin to replace the solenoid and reprogram the ecm/tcm for the harsh shifting. If you have high mileage you may have other internal transmission problems but this was the usual fix for those problems.
