No one knows transmissions like Sonnax, which is why their primary and secondary pressure sensors work exactly like your OEM parts. Gearbox pressure sensors determine the hydraulic oil pressure in various applications and help to specify the shifting pressure more accurately. This type of sensor may fail to function under hostile conditions or simply wear over time. When that happens, help keep your drivetrain running optimally with the Sonnax primary and secondary pressure sensors designed for your application.

Sonnax heavy-duty intermediate overrun clutch outer races eliminate weak points. Race failure is a chronic problem with high-torque loads causing race fractures at two stress points: the radial lube holes and the sharp inside corners at the base of the outer splines. Sonnax outer races are engineered with offset lube holes so rollers never travel directly over the holes, and they are spaced so only one roller is ever positioned near a hole, radically reducing the risk of fracture. Other design improvements to the splines, plus upgraded material and a custom manufacturing process, further improve durability, doubling the torque capacity over any OE or other aftermarket races. Sonnax heavy-duty intermediate overrun clutch outer races are direct replacements offering unrivaled reliability at any power level.

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.

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.

Sonnax output shaft supports are high-strength replacements for the stock Powerglide output shaft support. They are made from high-strength 6061-T6 billet aluminum to ensure rigidity where it is needed most. The supports are purposely built for racing, eliminating the provisions for the governor. A high-quality pre-installed roller bearing keeps friction losses to a minimum, while the billet aluminum construction lowers the weight dramatically. The Sonnax output shaft supports can be used with both long and short OEM and aftermarket tailshaft housings to allow for use in almost any drag racing application. They feature a true bolt-on installation for the popular Powerglide transmission and can benefit both bracket ET and professional drag racers.

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.

GM 6L80 and 6L90 transmissions often suffer failure of the 4-5-6 clutch assembly due to flexing and bowing of the backing plate (coning)—especially when your clutch-apply pressures exceed OE specifications. Sonnax clutch backing plates are designed to minimize flexing/bowing when the clutch is applied, drastically reducing the likelihood of clutch plate distortion. Their stiffer backing plate design outperforms OE and aftermarket plates.

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.

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
