Welcome to Grafco Electric, your trusted source for valuable information and expert advice on automotive repairs. In this comprehensive guide, we will walk you through the process of removing the 722.6 valve body and replacing the conductor plate, providing you with the knowledge and skills needed for a successful repair.

Why Replace the Conductor Plate?

The conductor plate plays a crucial role in the proper functioning of the transmission in vehicles equipped with the 722.6 automatic transmission. Over time, the conductor plate can become worn or damaged, leading to various transmission issues. By replacing the conductor plate, you can restore the optimal performance of your vehicle's transmission and avoid costly repairs down the line.

Step-by-Step Guide

Step 1: Gather the Necessary Tools

Before starting the removal process, it is important to gather all the tools you will need. Some of the essential tools include a socket wrench set, screwdrivers, pliers, and a torque wrench. Make sure you have a suitable workspace and adequate lighting for the repair.

Step 2: Prepare the Vehicle

Ensure that the vehicle is securely parked on a level surface and the engine is turned off. Engage the parking brake and chock the wheels to prevent any accidental movement during the repair process. It is also recommended to disconnect the negative battery cable to avoid any electrical mishaps.

Step 3: Drain the Transmission Fluid

Locate the transmission pan and carefully remove it to drain the transmission fluid into a suitable container. This step is necessary to access the 722.6 valve body and conductor plate. Once the fluid has been drained, you can proceed to the next step.

Step 4: Remove the Valve Body

Start by disconnecting the electrical connectors and solenoids attached to the valve body. Carefully loosen and remove the bolts securing the valve body to the transmission housing. Take note of their respective locations for reinstallation. Gently extract the valve body, ensuring no damage is caused to any internal components.

Step 5: Replace the Conductor Plate

Once the valve body is removed, the conductor plate is easily accessible. Carefully disconnect any wiring harnesses connected to the old conductor plate. Remove the screws holding the plate in place and take out the old conductor plate. Replace it with a new, compatible conductor plate, ensuring proper alignment and secure fixation.

Step 6: Reassemble and Test

Reassemble the valve body by following the disassembly steps in reverse order. Tighten the bolts to the specified torque values using a torque wrench. Ensure that all connectors, solenoids, and wiring harnesses are properly reconnected. Refill the transmission with fresh transmission fluid as per the manufacturer's recommendations. Start the engine and test the transmission for smooth shifting and proper operation.
