Technician servicing a disassembled automatic transmission on a bench

Your transmission plays a major role in vehicle performance and reliability.

Marshall’s Service Center provides professional transmission maintenance and service designed to help extend transmission life and improve performance.

There are multiple ways to service transmissions depending on vehicle type, condition, and manufacturer recommendations. Our technicians evaluate your vehicle, explain the recommended service, and obtain approval before any work begins.

Transmission Services May Include:

  • Transmission fluid exchange
  • Drain and fill service
  • Pan removal and inspection
  • Filter or screen replacement
  • Transmission performance evaluation
  • Leak inspection

Regular transmission maintenance can help prevent overheating, slipping, delayed shifting, and premature wear.

Preventative Transmission Maintenance

Transmission repairs can become extremely expensive if maintenance is ignored. Routine fluid service helps maintain lubrication, cooling, and proper operation.

Heat Is the Main Enemy of a Transmission

Automatic transmission fluid does its work under heat and pressure, and elevated temperatures shorten its service life considerably. Arizona summers, stop-and-go traffic, towing and long grades all push fluid temperatures up, which is why transmissions in this climate benefit from staying current on fluid service rather than following the longest interval in the owner’s manual.

Catching Problems While They Are Still Small

Delayed or hard shifting, slipping, a burning smell or fluid on the driveway are all worth an inspection promptly. Transmission repairs are among the most expensive work a vehicle can need, and the gap in cost between routine fluid service and a rebuild is large. We evaluate the vehicle, explain which service is appropriate for its type and condition, and get your approval before any work begins.

Signs of Transmission Problems
