What about Transmission Fluid?

Transmissions need transmission fluid to function properly. Having the right type and amount of transmission fluid in your car will help it continue to function properly and prevent unnecessary repairs. Transmission fluid has two purposes.

1) Lubricates the transmission gears.

When you shift gears, your transmission fluid makes this feel smooth and easy. The fluid also helps to keep the transmission cool so that it does not overheat.

1) Keeps hydraulic pressure at the right level.

Transmission fluid also helps to keep the proper pressure between your car’s engine and the transmission.

Why Change Your Transmission Fluid?

Changing your transmission fluid (or having us do it for you!) is one of the best ways to keep your car healthy. We suggest looking at your owners manual for the manufacturer’s recommendations about when to change the transmission fluid. However, we can always provide suggestions when needed. It’s important to change the fluid regularly for the following reasons:

• Metal chips come off gears and contaminate the fluid
• Additives and detergents in the fluid gradually deplete
• Sludge and varnish can build up in the fluid, making it less effective

Is Your Transmission Leaking?

Pay attention to any reddish fluids pooling up beneath your car when you park. This can indicate a transmission leak. Transmission fluid is essential to keeping your transmission running well and the sooner you get this taken care of the better shape your transmission will be in.

When you bring your car into the shop, we’ll inspect the hoses, gaskets, and seals of your transmission to find out what’s going on. Once we’ve found the problem, we will make all the necessary transmission repairs to keep your car running in tip-top shape.

Flushing Your Transmission

Flushing your transmission fluid every so often will keep your transmission running well. When you bring your vehicle into our shop for a transmission flush, we will inspect your transmission pan for debris, switch out the transmission filter, change the transmission fluid, and look for signs of corrosion.
