What is a Transmission Transfusion?
Like manual transmissions, automatic transmissions step down the speed of the engine, to something more useful, to drive the wheels. The automatic transmission still uses gears to do so but does not require the driver to manually operate the clutch and select the desired gear. Instead, using a hydraulic system, the automatic transmission engages and disengages the appropriate gears, depending on driver demand, engine speed, and engine load.
Automatic transmission fluid does not last forever, and so must be changed when it is worn out. Draining and refilling the transmission isn’t effective, however, since just a fraction of the fluid drains from the pan. Some automatic transmissions don’t even come equipped for drain and refill procedures. On the other hand, a transmission transfusion can usually replace more than 90% of the used transmission fluid in the system.
Why is a Transmission Transfusion Important?
Because it is constantly subjected to temperature and pressure changes, automatic transmission fluid must be specially formulated for the application. Still, automatic transmission fluid lifespan is limited. Some automatic transmissions suggest automatic transmission fluid replacement intervals anywhere from 30,000 miles to the life of the vehicle, depending on year, make, model, and usage. Still, with the average American car pushing 12 years of age, the “life” of the vehicle is going even beyond manufacturer expectations.
While even “lifetime” transmissions don’t even come equipped with a dipstick or drain plug, it may be a good idea to have the fluid level and condition inspected at least every six months. Whether or not your vehicle is equipped with a drain plug, oil pan, or dipstick, a transmission transfusion is the most effective way to keep your transmission operating clean, extending its life and useful mileage.
Why Might You Need a Transmission Transfusion?
Unless you have a leak, you’ll probably never worry about your automatic transmission, but here are a few reasons you might want to consider a transmission transfusion.
- If you use your vehicle under “Severe” operating conditions, such as mainly short trips, towing, or hard driving, then you might want to consider a transmission transfusion to remove burnt fluid and help remove deposits.
- If you smell burnt transmission fluid or the transmission fluid is black, a transmission transfusion is the surest way to ensure most of that worn fluid is eliminated from your transmission.
- If your transmission is slipping, vibrating, clunking, or exhibiting other unusual problems, a transmission transfusion may not solve the problem. In this case, ask your technician for a transmission inspection, which may require removal of the oil pan, transmission fluid filter, pressure checks, or other diagnostic services.
