Signs of Failure:

Replacing this valve when it goes bad is crucial because, if neglected, it can result in catastrophic damage to your TCU. Instead of spending $150 on parts and an hour of your time, you could end up spending thousands of dollars replacing your TCU or transmission. This happens because when the valve fails, coolant migrates out of it via the electrical connector plugged into it. It then travels up the wires of the wiring harness. If it reaches the TCU, you're in serious trouble.
