Engineered for serious performance applications, the Speedmaster PCE634.1013.01 is a full manual valve body upgrade kit designed for GM TH350 transmissions. Featuring billet CNC-machined construction, this kit delivers precise, consistent shift control while the included transbrake function allows for optimal launch performance on the strip. The spragless upgrade eliminates the one-way sprag clutch for a more direct power transfer and greater durability under high-demand racing conditions.
Designed as a direct upgrade for TH350 transmissions, this kit is ideal for drag racing and performance driving enthusiasts looking to maximize control over their shifts and improve overall transmission reliability. Full manual control puts gear selection entirely in the driver's hands, removing automatic shift tendencies for a true performance driving experience. Trust Speedmaster's precision engineering to take your TH350 build to the next level.
