Why Do You Transmission Fluid Service?

Nearly nine out of ten transmission failures are due to overheating and fluid contamination, according to the Automatic Transmission Rebuilders Association. Just like the oil in your car's engine, automatic transmission fluid (ATF) suffers from heat, friction, and electrochemical degradation. Once this process starts, your transmission's vital parts begin to clog with sludge and varnish deposits.

Unlike your car's engine where all the oil can be drained out, most of the transmission fluid doesn't drain into the transmission pan. Instead, it stays in the torque converter, valve body, and transmission cooler lines making a complete fluid drain impossible. In fact, the typical transmission service only replaces 25% of the contaminated fluid, leaving behind 75% contaminated fluid to mix with the new ATF.

According to automatic transmission fluid manufacturers, the addition of new fluid to contaminated fluid can actually cause sludge and varnish deposits to clog filters and restrict the flow of transmission fluid. This can result in a serious malfunction, or even complete failure of an automatic transmission.

Now there is an option. A transmission fluid flush to provide 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.

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 the need for a transmission.

Transmission Fluid Flush Includes:

• Road test for engine performance and transmission operation and shift patterns.
• Flush transmission cooler and cooler lines.
• Flush transmission valve body.
• Flush transmission torque converter.
• Thorough cleaning of all internal parts.
• Flush all contaminated transmission fluid out and replace all the transmission fluid with clean fluid.
• Install transmission additive to revitalize transmission seals and O-rings.
• Top off transmission fluid and road test.
