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.

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)

A pump that's been resurfaced or accumulated shaft spline wear creates excessive endplay of the forward and direct drums. This reduces sealing ring, clutch, bearing, and thrust washer life. Having the ability to shim both the lower unit sun gear addresses these problems. Sonnax offers forward clutch hub washers for a variety of transmission applications. Product benefits: * Washers take up the play between the forward clutch hub and the direct clutch housing, allowing front unit endplay to be reduced * Washers also stabilize the direct drum, reducing delayed reverse and improving 2-3 clutch circuit * Allows salvage of valuable hard parts

The Chrysler 46RH/RE, 47RH/RE, 48RE and A727 units used in high performance applications often bend or break the kickdown band strut. To help eliminate these issues, Sonnax offers heavy-duty kickdown band struts—made of solid, heat-treated steel that will not bend or break like other stamped struts. These quality replacements feature an extra-thick cross-section for maximum toughness to withstand the increased intermediate "band" applied forces that are common in high performance applications. Installation is easy: just remove the pan and valve body to expose the bottom of the transmission, loosen the adjusting screw to remove all tension from the band, then remove the original strut and insert your new one with the flat surface facing away from the band. Tighten the adjusting screw to manufacturer specs—and you're good to go!

Sonnax enhanced performance accumulator springs provide firmer 1-2 shifts for enthusiasts who appreciate quick, positive shift feel in their GM units. The design of these springs provides a performance shift feel, without reducing accumulator piston travel. This allows for a firmer—but still cushioned—shift that minimizes shock to the band and shafts. These springs also may be used as a replacement for THM 350 direct accumulator piston springs. Hit the road enjoying the perfect shift feel with Sonnax enhanced performance accumulator springs.

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

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

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
