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.

Extend the life of your forward clutch and input sprag with the upgrade performance of Sonnax heavy-duty 2-3 shift valves! Your factory valve is limited to applying the overrun clutch only in D3, 3rd gear; whereas these Sonnax valves apply it in D3, 1st, 2nd, and 3rd. This furnishes extra durability to clutch components in plow trucks, heavy-duty vehicles, and in high performance apps. The Sonnax 2-3 shift valves also work well with units operated by aftermarket electronic paddle shifters--allowing for full downshift engine breaking in 2nd gear, while the shifter remains in the D3 position. No special tools are required for installation; it's a transmission overrun clutch component worth exploring!

These sprags and roller clutch kits from TCI are all-new OEM assemblies. Replacing the forward sprag assembly and low-reverse roller clutch is a must when building a high performance 700R4/4L60E. These forward sprags are 29-element, which makes them ideal upgrades for earlier 700R4 transmissions that were built with weaker sprags from the factory.

If you're one of the millions of GM drivers with 700R4 or 4L60E/4L65E automatic transmissions that experience sluggish shifts, especially into second gear, you should consider swapping out your OEM servo for an ATI servo piston kit. Their piston kits are CNC-machined from 6061 T6 aluminum and are an easy upgrade. Don't be fooled by other servo assemblies that are nothing more than cleaned up OEM parts—ATI Performance Products has been producing quality performance-enhancing internal transmission components for decades.

When standard OE pins just won't do, use Sonnax extra-long Servo pin and seal kits to get the job done right! The Sonnax 4L60/4L60-E servo pin is longer than the longest OE pin. The pins extra length simplifies adjustment, eliminating the need for having to add length to the pin, itself. The Servo pins are made from chromoly steel, so they're durable for high performance applications as well as stock replacement. Dual PTFE seals have been added to improve sealing in the case bore and as well as an O-ring to improve sealing between pin and the 2nd gear Servo. The kits include pin, PTFE seals and an O-ring seal.

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
