How do you bypass a TCC solenoid?
To bypass the shift and TCC solenoids, you simply need to connect standard 194 light bulbs to these individual circuits coming from the PCM and then connect the other side of the bulbs to ignition B+. The light bulbs will then serve as a “load” which will simulate the solenoids.
What happens when a torque converter solenoid goes bad?
When the torque converter starts malfunctioning, you may feel shuddering and even slipping in overdrive. You usually notice your car shuddering because it feels like it’s vibrating. Your car will vibrate even when you’re not going very fast. The shuddering makes the car lag and is very noticeable.

What is torque converter clutch circuit?
The (TCC) torque converter clutch creates a one-to-one connection between the engine and the transmission that increases fuel mileage and reduces transmission fluid temperatures. Slippage consumes power during the coupling phase. Locking the converter shell to the turbine shaft prevents this slippage from occurring.
