fluid replacement

Proper transmission maintenance is like eating properly and exercising for the human body. It keeps the system “in shape” and “healthy” so that vehicular performance is not compromised. The absolute best way to achieve optimal transmission fitness is by attending regularly scheduled fluid changes. Making sure that the proper fluids are kept fresh in the transmission cools, cleans and lubricates the internal parts and helps with engine power transference and keeps your transmission system durable. A goal we have is to help our customers prevent the onset of a transmission failure or at least prolong it. Schedule an appointment with us today to have your fluid changed.


One of the most cost effective NON comprehensive methods of maintaining a transmission’s longevity, is by requesting a transmission pan (sump) service.
The service is normally performed after the the vehicle is road tested, scanned for Diagnostic Trouble Codes (DTCs), checked for adjustments, and visually inspected on a the lift by an experienced technician. That specially trained technician will then appraise the condition of the fluid and any debris in the pan in order to evaluate the longevity of the transmission. In most cases, the transmission pan (sump) is removed from the vehicle and around half of the transmission fluid is then drained from the system. The fluid filter is then replaced and the screen in is cleaned to allow the rejuvenated fluid to separate from the harmful remaining bi-products caused by friction material in the hydraulic stream.

The alternative to getting a pan service, is getting a flush of the transmission. This process combined with changing the filter and cleaning the screen can remove any existing debris which enables increased cooling, cleaning, and lubrication without much danger of damaging a newer transmission.

***Please Note*** This process can be dangerous for older transmissions with higher mileages because during a transmission flush, the new fluid (which contains a solvent) can potentially strip away needed surface area material which would cause a mechanical malfunction.

When the new fluid mixes with the remaining fluid in the transmission, it rejuvenates the fluid and begins cleaning the internal parts of the transmission. Because of the concentration of the solvent, the fluid (once added) cannot tell the difference between a dirty part and one that is overheated (but still functions). In addition, if the filter is not changed its ability to clean debris from the fluid is compromised. While we can perform both services, we always recommend getting the pan service since it is safer and better for the overall maintenance of the transmission.

Another service we offer is the cooler line flush. This is where we use a BG Services brand flush and fluid conditioner in concert with a Motorvav Tec III top of the line machine. We connect into the transmission cooler lines to flush the system. The way this works, is the first line gets disconnected from the system and then connected to the machine line in to receive old fluid that will go into a chamber below a diaphragm. The other line that comes out from the machine is then connected to the line going to the cooler which carries new fluid from the top part of the chamber above the diaphragm.
The car’s engine is then started which turns the torque converter and the input shaft on the transmission. The input shaft turns the transmission pump and it makes hydraulic pressure, causing fluid to flow through the cooler line. As fluid leaves the cooler line it enters the chamber on the flush machine. As the old fluid side of the diaphragm fills it pushes the diaphragm up and forces new fresh fluid into the transmission.

After a short process, the old fluid is collected in the machine and it is replaced in the transmission by new fluid. The machine cause no pressure on the system, and all fluid transfer is done solely by the transmission pump. This is far superior to just drain and fill that most shops offer.



**should have this type of service done every 30,000 miles,(with BG products a warranty often applies) but definitely before your automobile goes out of warranty. By looking in the pan you may get an indication that you are about to have transmission trouble that might show up right after you get out of warranty.**
Now, the question may come to mind…”What type of fluid do you put back into the vehicles?” Conventional? Synthetic? Manufacturer specific?

For lots of different reasons that is fairly simple: synthetic. Premium synthetic fluid is the best at lubricating the transmission, provide better traction to the clutches, remove heat better, and do not break down quite as fast under high temperatures. In fact, premium synthetic automatic transmission fluids (ATFs) will protect better and last 3-5 times longer than the conventional ATF.

***Note*** Some automobiles do require manufacture specific fluids and failure to utilize them may result in mechanical failure. In those special cases we use the manufacture specific fluids.
