Sonnax Vacuum Test Stand Kits
Vacuum testing is an efficient way to evaluate valve and valve body wear. A worn valve or valve body bore can result in incorrect pressures in the transmission, which may lead to poor performance or failure of the transmission.

Sonnax vacuum test stand kits help fill this need. Whether you're diagnosing a problem valve body or verifying your remanufacturing process, the Sonnax vacuum test stand kit will be an invaluable tool. Product details: * Quick, easy testing of valve bores * Yields repeatable numerical results for comparison and documentation * Anodized finish will stand up to years of use * Test stand features high-quality brass needle valves and a built-in test orifice for simple calibration * Clear Sonnax test plate and silicone pad ensure easy, securely-sealed testing Kit contents: * Vacuum test stand * Test plate * Vacuum plate sealing pad * Vacuum test foam pad * Push-to-connect fitting * Assorted testing tips (6) * Flexible tubing * Flared tubing with flared nut * Testing tip adapter tube

Sonnax Heavy-Duty Forward Drums
The ideal GM TH400 upgrade for any power level, Sonnax heavy-duty forward drums (34554-01) feature a unique combination of high-strength, light weight, and a cutting-edge design to optimize transmission performance. Racing applications quickly push the heavy, cast-iron OE drum over its limits, with failure most common at the weak point where the shaft and drum connect. The problem can be addressed with a larger spline and lighter-weight aftermarket aluminum drum—but durability becomes a huge issue with wear of the clutch splines, shaft spline connection, and seal ring bore. To dramatically reduce weight and deliver the ultimate in reliability, the Sonnax high-strength, chromoly steel drum is custom-engineered with several lightening features for a low rotating mass. It weighs 3 lbs. less than the OE drum and is just 3 oz. heavier than a common aluminum drum. Weight is reduced carefully, without compromising strength, by ribbing the front of the drum, adding clutch splines (28 vs. 14) and lightening holes, plus reducing the diameter inner section of the drum at the middle seal ring area. This versatile drum upgrade has an oversized 28-tooth shaft-to-drum spline and can be used with a variety of input shaft styles. This includes Sonnax 1 in. diameter, 30-spline heavy-duty input shaft 30280-02, Sonnax 1 1/8 in. diameter, 35-spline big input shaft 35280-02, and other aftermarket shafts with 28-spline connection between shaft and drum: * Ultra-modern drum delivers both high-strength and light weight for unrivaled performance at any power level * Compatible with Sonnax and other aftermarket 28-spline input shafts * Optimized for use with rubber clutch separators for applications with clean neutral setups * Clutch spline major diameter is reduced slightly, and two sets of full-length clutch splines added to back up clutch separators * Lightening holes correspond to input speed sensor locations in aftermarket cases for more accurate converter and shift data * Middle seal is eliminated—an aluminum clutch volume spacer kit 34554-11K is available separately for applications in which clutch fill/drain time may be a concern * Sonnax high-RPM checkball capsule 57510-01 is installed to eliminate pressure drop at high (5500+) RPM, a common problem with OE and other aftermarket checkballs

Sonnax Valve Bodies
Sonnax universal remanufactured valve bodies have been uniquely designed to fit a variety of '99-later Chrysler applications, regardless of OE checkball or solenoid configuration. The convenience of stocking one SKU number for various applications saves time, money and interchangeability confusion. The channel casting has been resurfaced to SAE recommended flatness and surface finish. The seasoned casting warpage is now eliminated, removing cross-leaks and manufacturing burrs that resulted in clutch distress and shift complaints. A new separator plate is also installed, along with gaskets, to seal the critical surfaces between the valve body and channel casting. Heavy-duty/high performance accumulator pistons with dual-guide seals are installed to prevent piston-to-bore scuffing and restore clutch pressures due to leakage. Patented Sonnax valves are installed to restore hydraulic pressures and eliminate shift complaints, trouble codes, converter concerns and overdrive clutch distress. Their patented accumulator cover plate—made from stronger, thicker material and secured with additional screws—is also installed to prevent flexing or breakage. To guarantee the highest level of operational performance, these remanufactured valve bodies are tested on state-of-the art equipment to verify that pressures match OE specification. Product notes: * One SKU fits all applications, saving time, money and confusion * Resurfaced OE channel casting eliminates warpage, burrs, and cross-leaks cost effectively * New separator plate and gaskets provide critical seal between cast surfaces * Patented Sonnax valves and pistons restore hydraulic integrity of circuits to eliminate shift complaints and clutch distress * Patented Sonnax accumulator cover plate stronger than OE to prevent flexing and breaking
