Sonnax heavy-duty remanufactured valve bodies are built to overcome chronic shift and converter clutch apply complaints. It provides firmer shifts and a moderately increased pressure curve to improve performance, especially in truck and towing applications. Numerous Sonnax valve upgrades are included to restore hydraulic clearances that lead to shift complaints, clutch distress, converter complaints and codes, solenoid issues and pressure problems. Line pressure rise has been moderately increased to overcome shift complaints, delayed engagements, and to increase holding power to the clutches. To guarantee the highest level of operational performance, this remanufactured valve body is tested on state-of-the art equipment to verify that solenoid feed, clutch, converter, and line pressures match or exceed OE specifications. Choose your preferred kit packaged for your transmission. The valve body includes the following: * Oversized TCC regulator valve and sleeve, and limit valve spring for firmer TCC application * O-ringed bore plugs and abuse plugs * New accumulator control valve and sleeve with spring * Oversized AFL line up * New forward accumulator piston and seal * New pressure switch manifold * New EPC solenoid * New TCC PWM solenoid Kit contents: * Remanufactured valve body * Separator plate * Upper case gasket plate * Lower valve body gasket plate * 1-2, 3-4 accumulator springs * EPC solenoid harness adapter for 2003 to later units * Sonnax line pressure booster kit

Order the model recommended for your vehicle application. Includes: * Gear shift lever * Underhood control module * Plug-in wiring harness

They can also be applied down-track to help manage engine load and power application to the rear wheels. Hughes Performance Pro Series Powerglide torque converter dump valve kits are also available as upgrades on their Powerglide transmissions.

FAST Bump Stager trans-brake controllers provide improved staging accuracy by allowing you to access the patented "transcreep" function found in FAST XFI—without the added expense of converting your vehicle to a full XFI system. Drag racers, like yourself, will be able to carefully pulse the trans-brake, enabling your vehicle to move forward slowly during staging, creating a higher degree of repeatability than racers can achieve manually. The complete Bump Stager kits come with everything needed for use, and a built-in 20 amp driver removes the hassle of wiring an external relay for most applications. They can be used in carbureted applications or with any aftermarket EFI system. Improve your staging accuracy with FAST Bump Stager trans-brake controllers.
