ACDelco 10-3019 - Automatic Transmission Sealer and Conditioner

Signs of Wear & Troubleshooting

• A transmission seal conditioner should be used only when minor fluid leakage is observed. Significant fluid leaks usually indicate a much larger transmission issue than worn-out seals and will likely require much more significant repairs.

Good Maintenance Practices

• Thoroughly check the state of your transmission seals before using a conditioner.
• If the seals are significantly damaged and causing major fluid leakage, it is likely that they will need to be replaced and a seal conditioner will not fix the problem.
• Carefully monitor the status of your leak after using the seal conditioner.
• Clean around the transmission seal area to allow easier evaluation of any new leakage.
• If the leak persists, further maintenance and repair will be required.
• Continue to check on your transmission seals regularly, even if the leak stops initially.
• The additives in transmission seal conditioners can fix the problem by immediately swelling the seal, but they may cause the seal to degrade over time.
