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.)

The Sonnax adjustable rear servo pin kit 34912-01K replaces GM TH400 and '95-earlier 4L80-E servo pins. OE pins have seven different lengths to allow for adjustment of the Low/Reverse band—but are no longer available from GM. The Sonnax pin kit has an adjustment range that covers the five longest OE pins to allow for accurate setting of the Low/Reverse servo piston travel. The pin features an O-ring groove to prevent leakage of line pressure past the case pin bore. Kit contents: * Servo Pin * Screw * (4) Small washers * (1) Large washer * (2) O-Rings

Sonnax Line pressure booster kits allow you to shift aggressively and then feel the tranny grab the clutches with more power when it changes gear. The larger boost valves and matching regulator springs raise line pressure progressively as higher pressure is commanded. These kits modify the sensor signal, which causes the computer to create a pressure increase. They're installed between the pressure sensor and vehicle harness using OE-style sealed connectors; no modifications are needed to the transmission.

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.

The OE pressure regulator valve design prevents adequate cooler flow at low rpm and high-pressure conditions, which can create overheating. Additionally, in 1999 and later vehicles, the factory EPC pressure was set high at idle, resulting in engine surge conditions in GM 4L80-E and 4L85-E units. Sonnax lube-regulated pressure regulator valves provide a significant increase in cooler flow under low rpm and high-pressure conditions that benefits all vehicles—and eliminates the need for reprogramming 1999 and later vehicles with high EPC pressure at idle.

Vehicles with GM 200-4R and 4L60 transmissions often have problems with poor reverse boost or upshifts in manual low. These are generally caused by a worn reverse boost valve sleeve or wear at the pump body. Sonnax offers a larger ratio (.283 in.) reverse boost valve kit to restore the hydraulic integrity of the assembly. Due to the differences in the thermal expansion rate of steel and aluminum when the transmission approaches operating temperature, the sleeve has been allowed excessive clearance and scrubs the bore. Additional details: * Sleeve O-rings seal the reverse boost circuit and prevent leakage from the pump body bore * Sleeve and valve are made from hardened steel for increased wear resistance * Sleeve lands have been lengthened to add better sealing and stabilizing capabilities to prevent bore wear * Reverse boost valve spool lands have been lengthened to aid in maintaining hydraulic integrity * Drop-in Zip Valve parts install quickly and easily

Transmissions showing symptoms of soft shifts from 1-2 or 2-3, periodic harsh shifts, or low line rise may be able to correct the problems with one of these Sonnax Line Pressure Modulator Plunger Valve kits. When sleeves become worn, electronic pressure control (EPC) oil can leak past the valve to cause the soft shifts; valves will also stick or hang up through wear, leading to the rough shift issue. Sonnax kits include a replacement modulator sleeve made from carbon steel to combat extreme wear, along with a durable plunger valve crafted from hardened alloy steel. The O-ring helps to prevent EPC oil loss. Sonnax Line Pressure Modulator Plunger Valve kits are produced for fitment on a variety of transmissions, including 6 and small 8-cylinder applications. Select the kit that's tailored to your vehicle.

In GM TH350 and TH350C units, the intermediate servo bore becomes scored from repeated cycling. The spring side of the piston has line pressure present in R, N, D. Excess leakage at the servo piston results in low line pressure and delayed engagements. During forward speeds, oil loss affects shift quality and reduces clutch life. To salvage cases, install a Sonnax intermediate servo sleeve kit (35709-01K). * Contains an aluminum sleeve and a replacement piston with a PTFE seal * Drop-in solution requires no machining of the transmission case * Contents: Sleeve, servo piston, and Seal PTFE
