Transmission fluid helps keep your vehicle’s transmission cool and lubricated. Getting a transmission fluid service is an important part of maintaining the health of your vehicle, which is why your vehicle manufacturer recommends you schedule regular transmission fluid service.

If your transmission fluid is old and breaks down, or becomes contaminated, it is no longer able to keep the moving parts in your transmission lubricated and cool. Over time, this could cause a malfunction of your transmission, requiring costly and time-consuming repairs. So bring your vehicle into Guaranteed Automotive & Transmission Service today for a full transmission fluid service.

And while you wait, you can rest easy in our clean, cozy lobby, complete with children’s playing area, Keurig coffee machine, and friendly staff. Check out what this customer said about our transmission fluid service:

“I recently purchased a 2013 F150 and wanted all the major fluids (transmission, transfer case, front and rear differential) changed. I called Guaranteed, they was able to get me in within a couple days and have my truck in and out before lunch. It was a great experience and done in the time frame I needed.”
