Hello,

The transmission control module controls the overall transmission operations. It is basically the brain of the transmission.
The control module is located in front of the right front seat under the carpet in the foot well.
A faulty control module can trigger hard shift or no shift. It can also put the vehicle in limp mode.

I have attached diagrams for your reference.

Please let me know of any questions.

Thank you.
