Sonnax enhanced performance accumulator springs provide firmer 1-2 shifts for enthusiasts who appreciate quick, positive shift feel in their GM units. The design of these springs provides a performance shift feel, without reducing accumulator piston travel. This allows for a firmer—but still cushioned—shift that minimizes shock to the band and shafts. These springs also may be used as a replacement for THM 350 direct accumulator piston springs. Hit the road enjoying the perfect shift feel with Sonnax enhanced performance accumulator springs.

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 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.)

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!

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.

Sonnax TCC regulator and isolator valve kits assist in recovering hydraulic control and renew TCC performance. Severe wear of the TCC (torque convertor clutch) regulator valve bore, caused by oscillation of the OE valve, allows the regulated converter to apply pressure to your exhaust. This is a primary cause for TCC-related slip code and overheated converters. Exhaust pressure also diminishes line pressure, which can result in burnt clutches. Excess wear at the isolator valve bore reduces TCC apply pressure. Reconditioning the bore and installing a Sonnax TCC regulator and isolator valve kit will restore normal TCC operation by reestablishing the hydraulic integrity of this circuit. Order the kit recommended for your transmission application. Features include: * Sleeve manufactured from highly wear-resistant aluminum * Hard-coat anodized aluminum regulator valve combats premature wear * Isolator valve lengthened to operate in unworn portions of the bore * Annular grooves help center valves in bore to reduce future side-load wear

Sonnax throttle valve plunger kits address the poor line rise or no detent downshifts that can be common complaints in vehicles with a stock overdrive transmission. The steel plunger continuously reciprocates within the aluminum sleeve, wearing out the sleeve. This wear (plus the weak OE spring) allows throttle valve feed oil to leak past the plunger and exhaust, resulting in the aforementioned issues that can lead to 3-4 clutch failure. Sonnax throttle valve plunger kits include an improved throttle valve spring designed to properly maintain higher line pressure and improved throttle valve performance. Order the kit recommended for your transmission application. Features and items: * High-quality aluminum sleeve prevents wear * Tight-tolerance sleeve and plunger restore hydraulic integrity * Eliminates the part throttle sleeve orifice * Spring * Sleeve * Plunger
