2003 Bonneville SE Torque Converter Clutch Solenoid

[Jaxstarke99]

Just spent $400 replacing the torque converter clutch solenoid in my 2003 Bonneville SE after

the Service Engine Soon warning light came back with a P0742 code (Torque converter clutch solenoid stuck on).

It didn't work. The transmission is still trying to go from first to third or fourth gear and won't downshift until

you nearly come to a complete stop and shifts really hard when it does decide to switch gears. I'm at a loss

as to what to check for next. Any ideas? Thanks.
