Transmission works perfect. Come up to a stop sign, no transmission. Turn car off then on turn it back on you have transmission. Has a code of P0742. Car is also supercharged.

Hello,

The code: P0742 - TCC (torque converter clutch) Stuck On.

This can be due to a faulty powertrain control module or torque converter clutch switch.
It could also be an issue with the switch not getting enough power or connection issue.

I have attached the diagnostics for that code (look below). This can help determine what is the reason you are having this issue.

Please let me know of any questions.
Thank you.
