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 actuator feed limit valve kits eliminates problems with the OE AFL valve design in GM 4L60-E, 4L65-E and 4L70-E units. OE designs have a large reaction area and are highly affected by side loading which wears the valve body bore, resulting in lower oil pressure to the shift solenoid and lower line pressures. Sonnax kits include a redesigned AFL valve and a wear-resistant sleeve to regulate pressure and re-establish proper pressure control. The hardcoat anodized aluminum valve features annular grooves to prevent side loading and has 54 percent more support by operating in the full contact sleeve. Sonnax kits include valve, sleeve, spring, and retaining clip.

GM 4L60, 4L60-E, 4L65-E. and 4L70-E input drum assemblies are known to crack where the input shaft is pressed into it (where the overrun clutch rides). Sonnax input drum reinforcement kits include a hardened steel sleeve that reinforces the input drum to prevent this failure. They also include a re-worked overrun piston inner seal, overrun piston, piston outer seal, and piston inner seal. No machining is required to use these kits.

Vehicles with GM 200-4R and 4L60 transmissions often have problems with poor reverse boost or upshifts in manual low. These are generally caused by a worn reverse boost valve sleeve or wear at the pump body. Sonnax offers a larger ratio (.283 in.) reverse boost valve kit to restore the hydraulic integrity of the assembly. Due to the differences in the thermal expansion rate of steel and aluminum when the transmission approaches operating temperature, the sleeve has been allowed excessive clearance and scrubs the bore. Additional details: * Sleeve O-rings seal the reverse boost circuit and prevent leakage from the pump body bore * Sleeve and valve are made from hardened steel for increased wear resistance * Sleeve lands have been lengthened to add better sealing and stabilizing capabilities to prevent bore wear * Reverse boost valve spool lands have been lengthened to aid in maintaining hydraulic integrity * Drop-in Zip Valve parts install quickly and easily

TransGo Performance offers solenoid repair kits for nearly a dozen automatic transmission applications, including models from Mopar and GM. Transmissions often come with contaminated governor pressure solenoids. This results in complaints of wrong gear starts, as well as governor solenoid and sensor performance codes. The computer uses the governor pressure solenoid to generate governor pressure relative to road speed, emulating what the hydraulic governor did in older 'RH' series transmissions. The computer varies the duty cycle to the PWM governor pressure solenoid to achieve the desired output pressure. Simultaneously, it monitors the feedback from the governor pressure sensor to confirm that the governor pressure is doing what it is commanded to do. When the solenoid sticks or is restricted, the computer notices that the pressure reading from the sensor does not match the desired governor pressure and sets a code which puts the unit in limp-in mode, resulting in 3rd gear start and no shift. These TransGo governor pressure solenoid repair kits contain everything you need to take apart the original equipment solenoids, restore the valve bore, then replace the spool valve, spring and cap with new ones. The repair kits include enough parts to rebuild multiple solenoids. The repair kits are available with or without tools. Order the model recommended for your transmission. * Corrects/Prevents/Reduces: -- Wrong gear start -- No upshift -- Governor pressure solenoid and sensor performance codes -- Limp-in mode

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.
