South Side Performance technicians have an extensive background in working with the internals of the Miusbubishi Evo X MR transmission. SS has been working hand in hand with several aftermarket performance companies to upgrade the SST transmission.

SSP has been producing aftermarket parts for the SST transmissoin for nearly a year now. There have been many hurdles along the way. The SST transmission has been plagued with an internal clutch basket sealing problem. The oem seals are prone to leak under high temps, and begin loosing pressure between shifts. This problem leads to clutch unclamping and miss shift issues.

SSP has solved some of these issues with the developement of our high temp. VITON seals. SSP has replicated the oem pistons A, and B, which uses a heavier gauge material in conjunction with a high quality VITON seal. This will insure the proper seal under even the most sever loads and driving conditions.

Viton Seal Specs:

• Heat resistant up to 450F


• Works in temps down to -60F


• Resists hardening


• Resists to all types of oils


• 0 pressure loss
