Sonnax pressure switch rebuild kits can help salvage your transmission electro-hydraulic control module (TEHCM), restore normal switch operation, eliminate codes, and provide renewed shift performance in all ranges. Some GM transmissions send various trouble codes related to internal fluid pressure failures to your TEHCM. These codes may be accompanied by torque converter clutch (TCC) apply problems or shift irregularities such as slipping, flares, harsh application, and bind-ups. Often, the cause is laminated portions of unobtainable OE pressure switches breaching, preventing normal switch operation. Avoid multiple breakdowns that can trigger failsafe mode and TEHCM replacement by ordering the Sonnax pressure switch rebuild kit recommended for your GM transmission.

Sonnax stator support shafts provide added strength and solid support to the torque converter stator. They are manufactured from high-quality, heat-treated alloy steel--and the roller burnish finish in the seal bore improves sealing for better pressure. The spline and knurl areas have been selectively induction-hardened to resist wear; a pronounced knurl enables more positive press fit. The Sonnax stator support shafts are specially-designed for severe-duty race applications.

Vehicles with a GM 8L45 or 8L90 automatic transmission may exhibit high or low line pressure that results in harsh/soft shifts, burnt clutches, loss of cooler and lube flow, and overheating of the transmission and converter. These problems may be caused by wear of the pressure regulator bore casting at the VFS signal port area and/or at the shuttle valve sleeve. Wear at the inboard port of the pressure regulator bore allows VFS (throttle) signal pressure to leak, preventing proper action of the pressure regulator valve and potentially allowing it to remain in the low line pressure position. Wear of the shuttle sleeve due to continuous oscillation of the shuttle valve creates a path for balance line pressure at the pressure regulator valve to exhaust, resulting in excessive low line pressure. Sonnax drop-in pressure regulator and shuttle valve kits restore hydraulic integrity to the lineup by addressing wear that subjects the transmission to either excessively high or low line pressure with upgraded materials and unique designs. The pressure regulator valve has been designed with a lengthened spring pocket spool at the VFS signal port area, which provides over double the sealing capability to this critical end of the valve and allows it to operate in unworn portions of the bore. The length of the critical shuttle valve diameter has been significantly lengthened to provide better sealing and durability of the assembly. Additional details: * Hardcoat anodized aluminum valves and highly wear-resistant billet aluminum sleeve combat premature wear * Pressure regulator valve VFS signal spool 200 percent longer than OE and operates in unworn area of the bore * Critical shuttle valve spool made 30 percent longer than OE for added sealing and durability * Drop-in Zip Valve parts install quickly and easily Kit contents: * Pressure regulator valve * Spring * Shuttle valve * Shuttle sleeve

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)

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

Stop leaks while reviving line pressure and torque converter clutch (TCC) operation by installing Sonnax O-ringed end plug kits. OE end plugs prevent critical pressure loss by capping the bore while also functioning as a valve stop. Trust the Sonnax O-ringed end plug kits designed for your application to help you cross the finish line!
