RennTech transmission upgrade consists of a complete transmission disassembly and inspection as well as a mechanical upgrade to the transmission clutch packs. This allows us the ability to maximize the amount of friction materials contained within the transmission and in turn, the amount of power which can be transmitted through each forward gear. During final assembly the transmission also receives all new gaskets, seals, o-rings as well as a new transmission pan filter.
