When these go out, the transmission may fail to shift to the next gear, or worse, the transmission may fail altogether.
How much does it cost to replace a Transmission Control Module?
Opening the transmission is a laborious task, which is why it is reasonable to expect labor costs of at least $300 to replace the transmission control module. In many older models ( especially automatic transmissions ) the module is located in an area of the engine that is much easier to reach.
Do you need a kick down cable for an automatic transmission?

On the opposite side of the spectrum, a slow or late shifting transmission will also be an indication that a problem with the kickdown cable exists. In this scenario, the kickdown cable is typically stretched and will cause a delay in the shifting process.
Why does an automatic transmission kick down to a lower gear?
Automatic transmissions kick down to a lower gear to make use of the greater power delivered at the engine’s higher rpm; this typically occurs when the driver attempts to accelerate from a constant speed, as if to pass.
Can a bad kick down Cable be replaced?
