Before we start, remember to always work safely by using jack stands when working underneath your vehicle. Here are the main steps:

Draining the Transmission Oil

Start by draining the transmission fluid and remove the drain plug using an 11-millimeter socket. Ensure to disconnect the car battery before beginning work on the transmission.

Removing Transmission Lines and Cables

Next, remove the transmission lines and cables, including the clip and bolt securing them in place. Tying them up with a zip tie will prevent them from falling and causing damage.

Accessing the Solenoids

Disconnect the wires and remove the bolts holding the valve body in place. Carefully lift the valve body out of the way and remove the screws to access the solenoids. Remember not to contaminate any parts during this process.
