Transmission Fluid Exchange Service

Volkswagen Transmission System & Hydraulic Oil 101

The Volkswagen Transmission is a sophisticated system with complicated inner mechanics that allow it to transfer the power produced by the engine into the drive wheels as variable torque. To deliver engine power into drive wheels, the transmission relies on a spectrum of gears, sensors, pinions, gaskets, and lubricating hydraulic oil that keeps everything lubricated and cool. The auto industry calls this lubricating hydraulic oil transmission fluid and it will eventually break down, get contamination, or leak to require an exchange.

Not only does transmission fluid serve as oil that keeps the transmission's components lubricated, but the fluid also acts as a hydraulic that transfers energy among the internal moving components. With the overall performance of the transmission and your vehicle being subjected to the condition and performance of the transmission fluid, it is an excellent maintenance decision to follow Volkswagen's recommendations for transmission fluid exchange or schedule service in response to any symptoms of defective performance.

What are the Symptoms of Defective Transmission Fluid?

When transmission fluid contaminates, leaks, or breaks down, you will need an exchange service to restore its reliable performance. Here are the most common symptoms associated with defective transmission fluid:

• Gears will not change properly or do 
• Gears change without driver input, without reason, or sporadically   
• Makes noises, such as grinding, clunking, or ticking 
• Dashboard warning light 
• Fluid overheats 
• Fluid found leaking
