Unlock the Secret: How to Easily Check Torque Converter End Play

Torque converter end play refers to the axial movement of the torque converter within the transmission case. Excessive end play can lead to transmission problems, including noise, vibration, and reduced performance.

Why is Checking Torque Converter End Play Important?

Checking torque converter end play is crucial for ensuring the proper functioning of the transmission. Excessive end play can cause the following issues:

• Noise and vibration
• Reduced transmission efficiency
• Premature wear and tear of transmission components
• Transmission failure

How to Check Torque Converter End Play

Checking torque converter end play is a relatively straightforward process that can be performed with a few basic tools.

Tools Required:

• Torque wrench
• Dial indicator
• Magnetic base
• Pry bar

Step-by-Step Instructions:

1. Safety First: Park the vehicle on a level surface and engage the parking brake.

2. Disconnect Battery: Disconnect the negative battery terminal to prevent accidental electrical shocks.

3. Remove Transmission Pan: Locate the transmission pan and remove it using a socket wrench.

4. Inspect Torque Converter: Inspect the torque converter for any damage or wear.

5. Attach Dial Indicator: Attach the dial indicator to the magnetic base and position it so that the probe tip rests on the torque converter.

6. Apply Axial Force: Using a pry bar, gently apply axial force to the torque converter in both directions.

7. Measure End Play: Observe the dial indicator reading to measure the amount of end play.

8. Compare to Specifications: Compare the measured end play to the manufacturer’s specifications.

Acceptable Torque Converter End Play

The acceptable range of torque converter end play varies depending on the vehicle make and model. Typically, the end play should be within 0.010-0.030 inches.

Consequences of Excessive Torque Converter End Play

Excessive torque converter end play can lead to a number of transmission problems, including:

• Noise and vibration
• Transmission slippage
• Reduced torque capacity
• Transmission failure

How to Fix Excessive Torque Converter End Play

If the torque converter end play exceeds the acceptable range, it may need to be replaced. The replacement process involves removing the transmission from the vehicle and replacing the torque converter with a new one.

Tips for Checking Torque Converter End Play

• Use a dial indicator with a resolution of 0.001 inches for accurate measurements.
• Ensure that the torque converter is properly seated in the transmission case before measuring end play.
• Check the end play in both directions to ensure consistency.
• If excessive end play is detected, consult with a qualified mechanic for further diagnosis and repair.

Takeaways: Ensuring Transmission Health

Checking torque converter end play is a critical step in diagnosing and resolving transmission problems. By following these steps and adhering to manufacturer’s specifications, you can ensure the proper functioning and longevity of your transmission.
