Castrol TranSynd 668 is a premium, full-synthetic automatic transmission fluid specifically formulated for Allison Transmission® on-highway automatic transmissions. TranSynd 668 provides oxidative stability, anti-wear performance, and friction durability, as well as TES 668™ specification differentiators such as extended anti-shudder durability and extended clutch friction durability. This fluid features an Allison TES 668 approval. The TES 668 spec is fully backwards compatible for TES 295® applications, but is not backwards compatible for TES 468™ applications.

Inside the PPE Double-Deep Spin-On Filter is 2.72 times more filter media surface area. This increased surface area allows improved fluid flow and filtering. The PPE Double-Deep Filter actually traps particles down to 15 microns, that is half the size of what the standard spin-on filter catches. These improvements help create a cleaner flow of oil to vital internal components, resulting in smooth, more responsive shifts.
