DmaxStore Allison Service Package (Fluid & Filter)

DmaxStore has put together this great package for our members to correctly service their Allison transmission.  These kits provide the correct amount of fluid and a DmaxStore Performance spin on external filter for 2001-2019 Duramax diesels using standard Allison transmission pans.

Kit includes:

• 2x Gallons of Allison Transynd synthetic fluid- (We have found this fluid to be far superior to anything else available.) It is completely compatible with Dexron 3 and Dexron 6 designed specifically for the Allison transmission.
• 1x DmaxStore Performance Transmission Filter (Standard or Extended)

Dmaxstore Note: (If you have an Allison deep sump pan you will need 3 gallons of fluid. Larger aftermarket pans will need approximately 3.5-4 gallons If you are dropping the pan to replace the internal filter you will use approximately 2.5 gallons on a standard sump pan)

Installation:

• Remove 15 mm drain plug on transmission pan and drain old fluid, this should be 7.4 quarts unless you are low on fluid to begin, reinstall drain plug.
• Remove old spin on filter, remove filter magnet located on top of old filter and clean it with a rag. Install magnet on new filter and fill with Transynd fluid, reinstall filter on transmission.
• Using transmission funnel fill transmission with 7.4 quarts of Transynd and check level.
• We recommend this service every 30-40 thousand miles to keep your Allison running its best. Allison does not recommend using a machine to filter or flush the transmission.

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.

Features:

• 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
  servicing.
• Excellent temperature reduction through reduced friction leads to longer oil and component life.
• Outstanding cold-flow properties enable faster oil flow to all critical components, particularly during cold starts.
• Optimized frictional characteristics gives smoother gear changing at all ambient temperatures and load
  conditions.
• Excellent shear stability properties help to retain full transmission performance over the entire oil-drain interval
