Back by popular demand and with an improved formula, B&M Synthetic Trick Shift transmission fluid is specially formulated for modern-day electronic automatic transmissions. The 100% synthetic base was chosen for its foam inhibitors, superior resistance to oxidation, and its high shear stable control additives for superior resistance to viscosity loss between maintenance intervals. Synthetic Trick Shift is optimized with special friction control additives preventing slip and shudder, resulting in smooth positive shifts. Also contains special wear and seal protection chemistry commonly found in premium factory transmission fluids preferred by O.E.M. manufacturers. Compatible with other types of automatic transmission fluids but for optimum performance, it is recommended to drain and replace all transmission fluid with B&M Synthetic Trick Shift. Available separately in 1-quart bottles. Note: Not recommended for use in CVT, Type F, or dual-clutch transmissions.
