Fluid Level Check & Fluid Replacement :

Transmission fluid lubricates and cools internal components while supporting smooth operation. Over time, fluid can become contaminated or lose effectiveness, so professional inspection and service are important. We will check your fluid levels. Low fluid levels can reduce lubrication, accelerating wear and tear and causing problems.

Replace the fluid every 30,000 miles to support proper vehicle operation. We’ll change your filter and replace the old fluid with fresh, new fluid. We’ll also clean your pan and replace the old pan gasket.

Common Signs of a Fluid Leak

A leak may produce fluid spots underneath the vehicle, low fluid levels, unusual transmission noises, slipping, delayed engagement, or difficulty shifting. Ignoring a leak can contribute to inadequate lubrication and increased component wear.

If you notice signs of a transmission fluid leak, professional inspection can help identify the source and determine the appropriate repair.

• Dark, dirty, or contaminated fluid
• Unusual odors
• Hard or inconsistent shifting
• Slipping
• Delayed engagement
• Unusual noises
• Fluid leaks or low fluid levels

Tranny Flush:

Around every 30,000 miles, the fluid begins to break down and lose effectiveness. This can lead to buildup and deposits, which can hasten erosion of your transmission’s internal parts. Regular tranny flushes remove that debris and keep your transmission clean. This increases your transmission’s life and performance.

Fluid Flush Services

• Fluid inspection and condition assessment
• Replacement or flush service
• Leak inspection and level check
• Inspection for signs of internal transmission wear
• Related transmission and drivetrain inspection

Regular service helps maintain proper lubrication and supports reliable transmission performance. The appropriate service depends on the vehicle type, manufacturer recommendations, and condition of the existing fluid.
