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.
