Allison Transmission 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%.
