Sonnax Clutch Backing Plates

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 Clutch Hubs

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.

Sonnax Pressure Switch Rebuild Kits

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 Hydraulic Line Pressure Booster Kits

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.
