1. Installing the Torque Converter

Begin by properly installing the torque converter onto the transmission input shaft. Ensure the torque converter is fully seated by rotating it while applying light pressure until it engages with the pump gears.

2. Ensuring Proper Fluid Levels

Before installing the transmission, prefill the torque converter with 1-2 quarts of the recommended transmission fluid. This helps avoid dry starts and ensures proper lubrication during the first start-up.

After installation, check the transmission fluid level with the engine running and the transmission in park. Add fluid as necessary. Cycle through all the gears (e.g., Park, Reverse, Neutral, Drive) to distribute the fluid evenly and recheck levels.

3. Clearing Codes Before Installation

Use a diagnostic scanner to clear any stored trouble codes in the vehicle's ECU before starting the new transmission. This ensures no previous codes interfere with the new transmission’s performance.

4. Transmission Cooler Flush or Replacement

Replacing the transmission cooler is highly recommended to prevent contamination from old debris that could damage your new transmission. If the cooler is not replaced, at a bare minimum, a Hot Flush is required to ensure all contaminants are removed before installation.

5. Adjusting the TV Cable (If Required)

For transmissions like the 700R4 or AOD, proper adjustment of the TV (Throttle Valve) cable is critical for shift quality and transmission longevity. Incorrect adjustment can lead to premature wear or failure.

Summary

By following these steps, you ensure a proper and successful transmission installation. Always refer to the manufacturer’s guidelines and use the recommended tools and equipment.
