Sonnax Lube Regulated Pressure Regulator Valves
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 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.

Sonnax Automatic Transmission Pressure Regulator Valve Kits
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 Line Pressure Booster Kits
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.

Fel-Pro PermaDryPlus Valve Cover Gaskets
Fel-Pro's PermaDryPlus valve cover gaskets feature precision edge-molded silicone rubber, which resists high heat and delivers reliable sealing on irregular surfaces. This silicone rubber is wrapped around a rigid carrier that adds strength to the gasket to resist being sucked in under high vacuum or blown out when under pressure. At the same time, it also prevents over-tightening of the mounting bolts. Note, however, that these gaskets are not intended for race applications.

Sonnax TCC Regulator and Isolator Valve Kits
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

Sonnax Automatic Transmission Cooler Bypass Valve Kits
Sticking of bypass components, spring relaxation, or poor ball seat in Ford 4R100 and E4OD units will allow the bypass to open at lower cracking pressure. This reduces TCC (Torque Converter Clutch) apply pressure, cooler flow at the overdrive section, and radiator flow responsible for heat transfer. Sonnax automatic transmission cooler bypass valve kits allow the bypass valve assembly to be rebuilt, salvaging the OE fittings and maintaining cracking pressure at 70 to 75 psi. Features: * Hardened steel T-valve provides secure check ball seat and adequate bypass flow * New spring cracks open at 70 to 75 psi to provide lube if cooler is blocked or restricted * Hardened alloy steel check ball resists damage * Seven new O-rings provide positive seal for cooler circuit * Drop-in Zip Valve parts install quickly and easily Contents: * T-valve * Spring * Check ball * O-rings -- One small -- Two medium -- Two large -- Two extra-large

Sonnax Automatic Transmission Reverse Servo Spacers
The Sonnax automatic transmission reverse servo spacers provide a simple, low-cost way to add durability to the GM 4L80-E and 4L85-E transmissions and eliminates the need to retrofit early design reverse servo pistons into late units. Due to a design change in 1996, it had been found that the reverse servo piston commonly breaks because it is stressed more than early servos. Installation of Sonnax reverse servo spacers reduce piston stress by increasing the contact area between the aluminum piston and spacer and incorporating a cushion spring washer. The new contact area is over two times the original and the pressure between the piston and the spacer is reduced by 60 percent. The reverse servo spacer kits easily install during assembly and does not require machining or other modifications. Excessively high line pressure in 'Reverse' is directly related to boost valve wear and cross-leaks into the EPC oil circuit. For maximum durability, inspect and replace the boost valve with one of the Sonnax 4L80-E boost valve kits (sold separately). Product features and benefits: * Increased contact area reduces pressure between apply pin and piston by 60 percent * Added Belleville spring washer reduces shock on piston * No machining necessary, drop-in components * Maximum durability for minimal cost

Sonnax Solenoid Switch Valve and Plug Kits
Solenoid switch valves and plugs in various Chrysler transmissions cause bore wear as they oscillate and stroke during operation. This wear allows pressure loss and cross-leakage, and often permits the plugs to cock and hang up in the bore. This can result in failsafe mode, various codes, bind-ups, and burnt overdrive or 4th clutches. In 41 and 42 series units, TCC concerns can result, including engine stalling due to improper lockup. Reconditioning the bore and installing a patented Sonnax oversized solenoid switch valve and plug kit restores vital clearances for renewed operation and control. Additional details: * Patented Sonnax plugs redesigned to prevent cocking * O-ringed end plug positively seals bore * Annular grooves help center valve and plugs in bore to prevent future side-load wear * Hardcoat anodized aluminum valve and plug combat premature wear * Fits bores containing OE switch valve with .453 in. diameter large spool only Kit contents: -- Valve -- Inner plug -- Outer plug -- End plug -- O-ring

Sonnax 1-2 and 2-3 Accumulator Control Valve Kits
Ford E4OD and 4R100 transmissions often display shifting irregularities which can be traced to problems with accumulator control valves. Wear ridges form as the valve moves in and out of the bore. Under high-pressure shifts, the valve is allowed to stroke too far, causing it to hang up on these ridges and block oil flow to the associated clutch. This results in soft shifts, loss of gear, and burnt clutches. Sonnax 1-2 and 2-3 accumulator control valve kits resolve these issues and provide a firmer-than-OE shift quality. (The kit fits either of those two locations.) Additional details: * The step machined into valve spool acts as an orifice to allow full oil flow to clutches when appropriate, preventing premature clutch failure * Reinforcement retaining clip attaches to OE clip to prevent over-stroking * Spring shims allow for selective increase of apply pressure to manipulate shift quality * Annular groove helps center valve in bore to prevent future side-load wear * Drop-in Zip Valve parts install quickly and easily

Sonnax Isolator Sleeve Kits
In listed GM transmissions, severe wear of the TCC regulator valve bore from the OE valve allows regulated converter apply pressure to exhaust. This is a primary cause for a TCC-related 1870 slip code and overheated converters. Exhausting apply pressure also diminishes line pressure, which results in burnt clutches. Excessive wear at the isolator valve bore reduces TCC apply pressure. Sonnax isolator sleeve kits (77754-ISO) in combination with Sonnax TCC regulator valve kit 77754-03K or 77754-04K allow you to restore hydraulic integrity of the apply circuit. Sleeves are manufactured from highly wear-resistant aluminum to provide full support for the valve and prevent side loading. Includes retaining ring and sleeve.
