Sonnax valve body check balls are lightweight orbs that seal better. Manufactured from tough, wear-resistant imidized plastic, these check balls conform to the separator plate ball seats, creating a good seal. Steel balls are heavy and hard, causing wear on your separator plate seats from repeated high impact, while elastomer rubber ones wear easily, reducing their size and sealing ability. For excellent results from your valve bodies, service them with Sonnax imidized check balls.

Worn babbit pump bushings in your GM Powerglide, 350, 400, or Allison AT540 transmission can allow the converter hub and inner pump gear to move off-center, thus causing damage to pump gears and the pump housing crescent. You can replace the worn originals with automatic transmission oil pump bushings from Sonnax. These direct replacements have tighter tolerances for improved fit over OE units, and they're lined with highly wear-resistant PTFE to help maximize the life of the older style and increasingly rare pumps. Order the bushings recommended for your application.

Sonnax servo release check valve kits are unique solutions. Since the GM 4L60 (700-R4) and 4L60-E Series transmissions were introduced, they have had inadequate metering of 2nd gear band servo release oil resulting in 3-4 clutch pack failure. The 3-4 clutch pack and 2nd gear band are just not properly synchronized. Sonnax servo release check valve kits combine an orifice with a ball check valve to resolve these issues and successfully extend the life of 3-4 clutches, and improve the 2-3 shift feel. Other benefits: * Provides sufficient exhaust so that 3-2 downshifts are smooth * Calibrates 3-4 clutch feed orifice without creating shift concerns

Sonnax clutch hub shims allow hub end play adjustment with a mix of various forward clutch components. These 3-shim sets permit you to limit hub end play, which is beneficial when optimizing the high clutch pack stack-up. The Sonnax shims fit between your small wear plate and drum to lift the hub out of the drum--reducing end play between the hub and sun gear flange, while maximizing clutch tooth engagement with the hub splines. This prevents the rear clutch friction disc from dropping off the clutch hub. Reduce and control end play with Sonnax clutch hub shims.

OE rear stator support bushings have a tendency to wear-out prematurely due to sub-optimal material composition. This wear can lead to bushing failure, loss of correct pressure to the E-clutch, and gear ratio or solenoid codes. Sonnax rear stator support bushings have an upgraded material composition to restore worry-free operation, superior wear characteristics, and eliminate premature deterioration.
