Partial Transmission Oil Changes

In many cases, a full transmission fluid change isn’t feasible without removing the transmission from the vehicle. This is due to the design of many automatic transmissions, which often do not have a simple drain plug. Instead, a partial fluid change is a more practical approach for most owners.

What is a Partial Change?

A partial transmission fluid change involves draining a portion of the old fluid and replacing it with fresh fluid. This method helps maintain fluid quality without the need for a complete transmission removal. Here’s how it typically works:

1. Draining Fluid: Typically, you can drain about 30-50% of the fluid from the transmission. This is often done through the transmission pan or cooler lines.


2. Adding New Fluid: After draining, new fluid is added to replace the old fluid. This helps to refresh the fluid without the need for a complete overhaul.

Justification for Partial Changes

Statistical data and expert recommendations support the practice of partial transmission fluid changes:

• Fluid Degradation: Over time, transmission fluid degrades due to heat, friction, and contamination. A partial change helps to remove some of the degraded fluid, improving overall performance.


• Cost-Effectiveness: Full transmission fluid changes can be expensive and labor-intensive. Partial changes are more affordable and can be done more frequently, helping to maintain fluid quality.


• Expert Recommendations: Automotive experts often recommend partial changes as a means of prolonging transmission life.
