How to Use Gearbox Stop Leak?

Published in Automatic Transmission Repair 3 mins read

Using a transmission stop leak product like Trans-X involves adding it directly to your vehicle's automatic transmission fluid, specifically not for use in CVT or manual transmissions.

What is Transmission Stop Leak?

Transmission stop leak products are designed to help seal minor leaks in the transmission system. They often contain conditioners that swell seals, helping to stop leaks and potentially rejuvenate older seals.

How to Apply Trans-X Transmission Stop Leak

Based on the information available, applying Trans-X Transmission Stop Leak & Tune-Up typically involves adding the product to your vehicle's transmission fluid reservoir. The exact process generally follows these steps:

  1. Locate the Transmission Fluid Filler Neck: This is usually found in the engine bay. Consult your vehicle's owner's manual if you are unsure of its location.
  2. Check Fluid Level (Optional but Recommended): Before adding any product, it's wise to check your current transmission fluid level according to your vehicle's manual (often done with the engine running and warm, while the car is in Park or Neutral). Ensure there is enough room to add the stop leak without overfilling.
  3. Add the Stop Leak: Pour the recommended amount of Trans-X stop leak into the transmission fluid filler neck. Be careful not to spill.
  4. Close the Filler Neck: Securely replace the filler cap.

Based on the reference: Remember to close up the filler neck after adding the product.

Important Restrictions

It is critical to understand that not all transmissions are compatible with this type of product.

According to the reference provided:

  • Trans-X Transmission Stop Leak should not be used in CVT (Continuously Variable Transmission) or manual transmissions.

Using this product in an incompatible transmission type could potentially cause damage or affect performance. Always check the product label and your vehicle's owner's manual for compatibility before use.

When to Consider Using Stop Leak

Transmission stop leak is typically considered for minor leaks. It is not a permanent fix for severe leaks, damaged seals, or internal transmission problems. If you have a significant leak or performance issues, it's best to consult a qualified mechanic.
