Solenoid Stabilization Retainer
Part No. 105740-19K

Package Quantity: 6

The heavy linear force solenoids (LFS) in listed Allison, GM and Ford 10-speed transmissions are held in place by small spring retainers that are prone to collapse. When the retainers collapse, the solenoid wobbles in the bore, causing damage to the casting at the clutch valve bore opening. These LFSs actuate by extending a small pintle about .090" to stroke the inboard clutch control valve. When the spring retainer collapses and the LFS is off-center, the pintle cannot stroke the clutch control valve appropriately, resulting in shift complaints and converter issues. Valve body damage can also occur if the LFSs remain loose, resulting in valve damage during rebuild.

Sonnax solenoid stabilization retainer 105740-19K replaces OE clips and provides 32% more surface area to create more support for the solenoid. Another design upgrade is the top of the clip is rolled over to create a positive stop for the flexible side to land against, furthering the prevention of retainer collapse.

• 32% More casting-to-solenoid surface area for better support and leverage
• Positive stop retainer feature to prevent collapse
• Drop-in Zip Valve™ parts install quickly and easily

Main Pressure Regulator Valve Kit
Part No. 105740-12K

Wear in the main pressure regulator bore and on the outboard spool area of the valve is common in listed GM and Ford 10-speed transmissions. This wear minimizes line pressure control resulting in delayed shift engagement, poor shift quality and burnt clutches. Wear at the inboard spool and bore can lead to converter apply issues.

Installing the drop-in Sonnax main pressure regulator valve kit 105740-12K eliminates the leakage of line pressure signal oil to exhaust with the incorporation of an extended front valve spool. This valve spool is 270% longer than the OE spool, so actuates in unworn areas of the bore. The O-ringed end plug provides a positive seal and prevents critical signal fluid from leaking to exhaust. Both of these Sonnax features ensure your units will have proper line pressure control through all drive ranges.

• Extended outboard spool is 270% longer than OE and actuates in unworn areas of the bore
• O-Ringed end plug provides positive seal to prevent critical signal fluid from leaking to exhaust
• Hardcoat anodized aluminum valve combats premature wear
• Drop-in Zip Valve^TM parts install quickly and easily

TCC Regulator Valve Spring
Part No. 105740-29

Package Quantity: 5

The OE valve spring is subject to breakage or fatigue failure and can prevent proper release of the converter clutch. Correcting these concerns would normally require replacing the valve body. Installing Sonnax TCC regulator valve spring 105740-29 restores proper control of the valve.

• Replacement spring maintains OE functions and pressures
• Manufactured from upgraded material to increase spring strength and resiliency

Pump Vane
Part No. 124533

Package Quantity: 100

Sonnax pump vane 124533 is available for rebuilding GM 6T70/75 (Gen. 1), 10L60/80/90 (Gen. 1 & 2), Ford 6F50/55 and 10R60/80/90 transmissions. It is a cost-effective alternative to replacing an entire pump rotor assembly.
