Mitsubishi SST Trans Fluid - 4 Liters


OEM Mitsubishi DiaQueen SST Transmission Fluid - 4 Liter Container.

Mitsubishi recommends that the fluid and filter be changed every 60,000 miles, but this is way too long and can cause problems with clogged sump filters, layers of dirt caked on all parts, and fluid break-down.  Jacks Transmissions recommends changing the fluid every 30,000 miles to help keep things clean and happy. Don't forget to change the filter too! It can be found Here.

The TC-SST (EVO X and Ralliart) transmissions use 7.5 Liters, but we recommend installing at least 8 Liters or a max of 10 Liters if the vehicle has a larger cooler and is raced heavily.

Jack, owner of Jacks Transmissions, also owns a vehicle with an SST that is driven everyday.  Jack has spent a lot of time and money trying to find a cheaper alternative to the Mitsubishi DiaQueen fluid.  We have tried Castrol, Ebay fluids, and Pentosin.  None allow the SST to operate as it should and we have found that the Mitsubishi fluid truly is the best.
