PPE Double-Deep External Spin-on Cooler Filter
Stock spin-on transmission filters come up short.

PPE recognized the need for better filtration for the hard-working Allison 1000 and 2000 transmissions, so a superior filter was developed which addresses limitations of the standard "shorty filter".

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.

Do more to protect your Allison transmission and realize better performance. Don't come up short. Spin-on a PPE Double-Deep Premium Filter today.

*Note:  Must reuse drain plug and magnet(s) from original pan and external filter

Castrol TranSynd 668 Fluid

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.



  • Delivers improved gear protection.
  • Delivers extended anti-shudder durability.
  • Delivers extended clutch-friction durability.
  • Excellent corrosion and foaming resistance.
  • Excellent thermal and oxidative stability that helps to prevent deposits and oil thickening.
  • Excellent transmission cleanliness under all conditions permits extended oil-drain intervals and decreased
  • Excellent temperature reduction through reduced friction leads to longer oil and component life.
  • Outstanding cold-flow properties enables faster oil flow to all critical components particularly during cold starts.
  • Optimized frictional characteristics gives smoother gear changing at all ambient temperatures and load
  • Excellent shear stability properties help to retain full transmission performance over entire oil-drain interval.
