Re: Torque Converter 99 Grand Am

That means the torque converter clutch is not locking up. You'll want to diagnose it further if you do any regular highway driving as it helps a lot on the efficiency of an A/T (gives better MPGs). If you dont drive much and only drive in the city, I probably wouldn't worry about fixing it. To test the solenoid, unplug the connector and measure the resistance. If it's open, the solenoid is bad.
