Allison extends drain intervals for TranSynd

Allison Transmission has extended drain intervals for TranSynd synthetic automatic transmission fluid (ATF). The company has also begun using the fluid as factory fill for its AT, MT, HT, MD HD, B, and MH Series transmissions.

New drain intervals for TranSynd have been set at 75,000 miles for severe-duty and 150,000 miles for general-duty application. Previously the fluid was rated for 50,000 severe-duty and 100,000 general-duty. As part of the drain interval extension, Allison has also begun using Gold Series oil filters on all its WT products. These filters offer increased filtration capacity that also helps extend TranSynd drain intervals by up to 50%.

Engineered for Allison by Castrol, TranSynd has been tested and approved to the Allison TES-295 transmission fluid specification for severe-duty and extended drain intervals. The product also meets the General Motors Dexron III specification and has been licensed by General Motors to carry the Dexron III trademark.
