Transmission Service

Transmission Service – Recommended every 30,000 miles/15,000 miles for vehicles used to tow or haul

Service Includes: Rather than just removing the fluid found in the bottom of the pan, the entire transmission is cleaned and replenished with the use of special equipment. The transmission and its torque converter have all of their old contaminated fluid removed while new fluid and premium conditioners are added. We also check cooler and hoses for leaks and inspect the shift cable & all linkages.
Why: When exposed to the high heat of modern transmissions, transmission fluid deteriorates over time, turning from a clean red to burned brown color, reducing its effectiveness. Deposits also begin to form around the transmission’s many moving parts, resulting in valves that stick and gears that slip or are sluggish and chatter as they shift. This service preserves the proper function of the transmission and reduces internal wear resulting in lower transmission failure rates.
Your transmission is one of the hardest working parts of your vehicle. With this service it will shift smoothly and effortlessly for many more trouble-free miles.
