Additional Informaion

Better Protection With Full Synthetic ATF

ATF (Automatic Transmission Fluid) in a Duramax Allison transmission is more than just a lubricant; it's a critical component of the transmission. This automatic transmission fluid transmits energy between the engine and driveshaft, removes heat, lubricates, enhances seals, protects, and acts to maintain constant friction properties between friction plates and reaction plates. TranSynd fulfills all of these functions far better than conventional automatic transmission fluids. 

Full Synthetic vs. conventional Transmission Fluid

Since full synthetic transmission fluids allow for extended drain intervals, TranSynd helps lower the costs for maintenance and downtime on your Duramax. You save on the cost of transmission fluid, replacement filters, disposal, and liability of used fluid. Most importantly, you benefit from reduced wear, better performance, and longer service life from your Allison Automatic. The bottom line is that the superior lubricating protection of a full synthetic transmission fluid such as TranSynd results in even greater productivity and lower operating expenses.
