The kit includes a drop-in USA-made hardened steel TCC relay boost valve and bushing that will restore the hydraulic circuit integrity for type two, three and four valve bodies except some Lexus models. This hardened steel boost valve and bushing assembly provides you with a durable direct replacement for the soft aluminum OEM assembly that is prone to wear. The kit also comes with everything you need to recalibrate the accumulators, separator plate feed orifice's and pressure regulation for a better shifting and a more durable transmission.
