Sonnax shift improver performance packs combine innovative heavy-duty performance calibration for firmer shifts under load without sacrificing low-speed drivability. The precision components in these kits upgrade your transmission for maximum achievement and durability by recalibrating pressures, recalibrating shift accumulation, and including improved parts for areas that commonly wear. They are suitable for any heavy-duty application and are a critical foundation for other upgrades when modifying the transmission for high performance use. Sonnax shift improver performance packs additional facts and features: * Shorter shifts, which get progressively firmer with load * Faster pressure increase and higher overall pressure for greater clutch/band holding power * Three ultra-reliable, patented, billet pinless accumulator pistons * Unique 1-2 accumulator spring combination for shifts with character * Improved high rpm pressure * Third accumulator valve gets the 2-3 right the first time, every time * Consistent results, no guessing on calibration * Prevents worn accumulators and separator plate * Optional TCC on-off conversion prevents excess TCC pressure

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 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.

Sonnax heavy-duty remanufactured valve bodies are built to overcome chronic shift and converter clutch apply complaints. It provides firmer shifts and a moderately increased pressure curve to improve performance, especially in truck and towing applications. Numerous Sonnax valve upgrades are included to restore hydraulic clearances that lead to shift complaints, clutch distress, converter complaints and codes, solenoid issues and pressure problems. Line pressure rise has been moderately increased to overcome shift complaints, delayed engagements, and to increase holding power to the clutches. To guarantee the highest level of operational performance, this remanufactured valve body is tested on state-of-the art equipment to verify that solenoid feed, clutch, converter, and line pressures match or exceed OE specifications. Choose your preferred kit packaged for your transmission. The valve body includes the following: * Oversized TCC regulator valve and sleeve, and limit valve spring for firmer TCC application * O-ringed bore plugs and abuse plugs * New accumulator control valve and sleeve with spring * Oversized AFL line up * New forward accumulator piston and seal * New pressure switch manifold * New EPC solenoid * New TCC PWM solenoid Kit contents: * Remanufactured valve body * Separator plate * Upper case gasket plate * Lower valve body gasket plate * 1-2, 3-4 accumulator springs * EPC solenoid harness adapter for 2003 to later units * Sonnax line pressure booster kit

Stripped bellhousing bolts? The cause is usually the loose fit of standard Torx bits, which damage the bellhousing bolts during removal or installation of the bolts. The solution to this problem is Sonnax Torx Plus bits. Specially designed for removing 4L60E bellhousing bolts, Sonnax bits have a tighter fit with the drive head of the bolt, helping to avoid rounding out the bolt head or the bit, and prevent the bit from walking out of the bolt head. Also, these Sonnax tools permit higher torque loads to be applied, which are often needed to remove extra-tight bolts.

ACDelco Type III-H automatic transmission fluid is a premium quality lubricant for use in a variety of passenger cars and light trucks. It is formulated with select base oils and additives to meet the heavy demands placed on automatic transmissions, including the latest generation of electronically controlled transmissions. ACDelco Type III-H is recommended in any transmission that calls for Type III-H, Type III-G, Type II-E, Type II, or Type A fluids in all automatic transmissions built by GM that do not require DEXRON VI. It can also be used in some hydraulic and compressor systems where excellent low-temperature flow ability is required. As always, consult your owner's manual for the correct fluid requirements.

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)

Continuous oscillation in relay valve and sequence valve bore causes wear that prevents proper hydraulic control. You can recover hydraulic control and renew 2nd and 4th gear operation by reconditioning the entire bore and installing a Sonnax oversized 4-3 sequence valve kit. These kits address wear on the inboard two spools that is increasingly more common in aging valve bodies. Wearing at these spools can allow valuable 4th servo feed leakage, resulting in no 4th and 2-4 band wear, and can also allow leakage of 2nd clutch oil needed to apply the 2-4 band in 2nd gear, resulting in poor 2nd gear shifts. Leaking at the OE end plug also allows oil loss that can leave 4th gear inoperable. Sonnax oversized 4-3 sequence valve kits feature hardcoat anodized aluminum valves to combat premature wear and O-ringed end plugs to help prevent 4th gear oil loss. Kit contents: * 3-4 relay valve * 4-3 sequence valve * Spring * End plug * Two O-rings (1 extra)
