Transmission Service

Low fluid levels can affect the safe driving performance of the vehicle and damage internal parts if not properly maintained. Close to 30 percent of vehicles fail inspections because of low, overfull, or dirty motor oil. More than 1/4 of vehicles inspected have either low, overfull or burnt transmission fluid.

If your car's transmission is showing signs
of contaminated transmission fluid, slippage, rough or hard shifting, this procedure is the first thing you should try before it becomes necessary to perform major repair work or even replace your transmission.

Transmission Flush

Getting a transmission flush is an easy way to prolong the life of your engine!

A transmission fluid flush provides you with the safe removal of varnish and sludge deposits and cleans all internal transmission components, including the transmission cooler, valve body, and torque converter. This service is also the best way to remove wear metals that are slowly grinding away on your transmission's internal components along with most of the old, contaminated ATF. Your car's transmission is thoroughly cleaned and protected with fresh ATF and conditioners that revitalize the seals and O-rings in the transmission.


Transmission fluid that has been worn out and oxidized can cause damage to your engine in a number of ways. Oxidized fluid does not have the same protection and lubrication quality as fresh fluid. Contaminations from old transmission fluid can also collect in valves, bearings, and clutches inside the transmission, causing them to stick and fail.


Transmission fluid breakdown is the number one cause of transmission failure, according to the Automatic Transmission Rebuilders Association (ATRA). The cost of flushing a transmission at Wallace Autos is minimal, while replacing a worn-out transmission can cost between $1500 and $2000 and can lead to other costly repairs.


In order to keep your transmission, and ultimately your entire engine, running for as long as possible, flush the transmission every 30,000 to 50,000 miles. However, some experts recommend against flushing the transmission in higher-mileage vehicles in which the transmission has not been properly maintained, as the new fluid can cause solidified contaminants to break off and damage the moving parts of the transmission. Please ask your technician at Wallace Autos for the proper recommendation for your vehicle.
