The feed limit low valve in listed GM transmissions limits line pressure feed to the default disable solenoid and control valves. Feed limit low pressure is also connected to the boost ball system for "A" and "B" clutch control. This feed limit low valve is subject to significant side-load force, resulting in severe wear and pressure loss to the default disable solenoid and connected control valves. Such pressure loss can put the vehicle into default mode at high speeds, resulting in momentary wheel lockup, sudden downshift to 2nd gear, harsh shifts or a P0747 code. The feed limit low valve can wear out in as little as 30,000 miles, with many vehicles requiring service by 35,000 miles. A national recall from GM includes installing updated software that monitors valve performance and wear, then triggers a check engine light and reduced propulsion message 10,000 miles before failure. Vehicles are then limited to 5th gear, commonly referred to as limp mode, until the valve body is serviced to address the failed valve. Sonnax patented this drop-in feed limit low valve kit to overcome bore wear, restoring proper valve function immediately without the need or expense of replacing the entire valve body. The valve reroutes the balance circuit through an internal passage, significantly reducing the side-load force, while upgraded materials prevent future wear. * The kit overcomes drivability issues related to the GM 10-speed wheel lockup recall * Patented valve and sleeve combination overcomes bore wear and significantly reduces future side loading of the valve * Hardcoat anodized aluminum valve and wear-resistant sleeve combat premature wear * Drop-in Zip Valve parts install quickly and easily * Kit contents: -- Valve -- Sleeve -- Spring -- Retainer -- Drill -- Rivet (Note: The OE feed limit low valve is susceptible to premature wear and therefore a critical failure point. Replacing the valve is recommended even if the transmission isn't exhibiting problems and the valve passes a vacuum test.)

Sonnax case saver retainers are designed for 1999 and later GM 4L80-E units—and are the only intermediate clutch retaining ring case saver that allows the intermediate band to be retained. The case savers fit over the intermediate band anchor lug inside the case and extends rearward to support the intermediate clutch backing plate retaining ring, preventing case lug blow-out. Over the years there have been a variety of case saver designs, however, all required eliminating the intermediate band, as is often done in drag racing trans-brake applications. Only Sonnax case saver retainers support the intermediate clutch retaining ring yet are thin enough to allow the intermediate band to be installed to provide case lug protection in all applications.

Sonnax knows you want your transmission to shift like a dream. Their automatic transmission bands are extra-wide intermediate bands suitable for heavy-duty, commercial, and 4x4 vehicles. These drop-in replacements provide 15 percent more holding capacity and feature a 60 percent thicker case anchor, decreasing the chance of band failure under severe conditions. (Note: The red-lined version of these Alto bands is designed for high-torque street racing applications. The Kevlar®-lined version is too aggressive for street use and best suited for high performance racing applications.)

GM 8L45 and 8L90 transmissions often suffer burnt clutches, shift concerns, low line pressure and/or converter apply complaints—due to excess wear in the signal accumulator piston bores in the control solenoid valve body casting. This wear allows valuable VFS signal pressure to exhaust, preventing proper shift control, line pressure regulation, and/or converter clutch apply. Sonnax drop-in signal accumulator piston kits allow bores to be reconditioned quickly and easily with no reaming required. The hydraulic integrity of the VFS signal pressure circuits are re-established, and future wear prevented with positive sealing and wear-resistant components. Features include: * Hardcoat anodized aluminum piston combats premature wear * Annular grooves to reduce wear rate * Highly wear-resistant sleeve to prevent future wear * Positive sealing O-ringed plug prevents leakage in already worn bores * Mating spring to re-establish OE dampening action * Drop-in Zip Valve parts install quickly and easily * Available for a variety of Chevrolet, GMC, and Cadillac transmission applications Kit contents: -- Sleeves (4) -- Pistons (4) -- Springs (4) -- O-rings (6), 2 extra -- End plugs (4)

Extend the life of your forward clutch and input sprag with the upgrade performance of Sonnax heavy-duty 2-3 shift valves! Your factory valve is limited to applying the overrun clutch only in D3, 3rd gear; whereas these Sonnax valves apply it in D3, 1st, 2nd, and 3rd. This furnishes extra durability to clutch components in plow trucks, heavy-duty vehicles, and in high performance apps. The Sonnax 2-3 shift valves also work well with units operated by aftermarket electronic paddle shifters--allowing for full downshift engine breaking in 2nd gear, while the shifter remains in the D3 position. No special tools are required for installation; it's a transmission overrun clutch component worth exploring!

Sonnax hydraulic line pressure booster kits contain stronger pressure regulator springs and large ratio boost valves designed to work together, providing progressive pressure increases as driving conditions become more demanding. Their springs are approximately 10 percent stronger than OEM and more conservative in impact than other aftermarket kit springs. Large ratio boost valves provide higher pressure incrementally and when it's needed the most. The combination of these springs and valves in the Sonnax hydraulic line pressure booster kits gives you the best of both worlds--a modest pressure increase at the low-end, with a high-end pressure that's equal to or greater than that of other aftermarket kit springs.

GM 6L45, 6L50, 6L80 and 6L90 automatic transmission units may exhibit multiple line pressure and cooler/converter/lube flow problems due to excess wear in the pressure regulator bore. Deterioration at the balance spool end allows critical fluid loss, resulting in high line pressure, harsh shifts, and overheating due to reduced cooler/converter flow. Wear at the outboard spool robs converter feed pressure and lowers line pressure, resulting in soft shifts and burnt clutches. Installing a Sonnax pressure regulator valve kit restores the hydraulic integrity of these circuits for proper line pressure control in all ranges. A new pressure regulator valve outer spring is also included to replace weakened original springs and provide a modest 5 psi increase across the pressure curve. Additional details: * Hardcoat anodized aluminum valve combats premature wear * Lengthened critical spools operate in non-worn portion of bore for added stability and wear prevention * Annular grooves help center valve in bore to reduce future side-load wear * Drop-in Zip Valve parts install quickly and easily Kit contents: * Valve * Spring * Drill bit .040 in. * 2 checkballs (1 extra)

Many Sonnax clutch hubs are designed for the extra-duty requirements of drag racing with Powerglide and other GM transmissions, for instance. Machined from a high-quality medium carbon steel forging, most hubs will accept five friction discs for the added load capacity needed in high horsepower race cars. All splines and thrust surfaces are precision-machined to exacting tolerances, and the unique lube hole pattern is designed to reduce drag on the friction discs in low gear. Sonnax clutch hubs are also available with or without lightening holes to reduce rotational weight.

When standard OE pins just won't do, use Sonnax extra-long Servo pin and seal kits to get the job done right! The Sonnax 4L60/4L60-E servo pin is longer than the longest OE pin. The pins extra length simplifies adjustment, eliminating the need for having to add length to the pin, itself. The Servo pins are made from chromoly steel, so they're durable for high performance applications as well as stock replacement. Dual PTFE seals have been added to improve sealing in the case bore and as well as an O-ring to improve sealing between pin and the 2nd gear Servo. The kits include pin, PTFE seals and an O-ring seal.
