(Engine & Transmission)

Certified Service technician checking on the engine and transmission of a vehicle.

Repairing a modern vehicle is more science than elbow grease. The engine and transmission are complex, intricate systems that use hardware and software technology with more moving parts than most vehicle systems. Diagnosing a problem can be a complicated process because one problem could actually be a sign of a number of other underlying issues.

 

If you’re experiencing a problem, you can trust Certified Service to help you find the best solve for your vehicle’s health.

Checking Automatic Transmission Fluid

Certified Service technician checking on the automatic transmission fluid.

It is not necessary to check the transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to your dealer and have it repaired as soon as possible.

 

There is a special procedure for checking and changing the transmission fluid. Since this procedure is difficult, this type of transmission repair should be done at your dealer. Change the fluid at the intervals listed in the Maintenance Schedule of your Owner’s Manual and be sure to use the fluid listed under Recommended Fluids and Lubricants.

When to Have Automatic Transmission Fluid Changed

Automatic transmission fluid should be drained and replaced as listed in the Maintenance Schedule of your Owner’s Manual.

When To Have Manual Transmission Fluid Changed
