Product Description
Sonnax part number: 105740-61K
In GM 10L1000 transmissions, wear in the relief piston bore can increase the risk of the piston binding. This causes fluid to drain out of the converter, leading to delayed converter charge and delayed engagements.
Installing drop-in Sonnax relief piston kit 105740-61K seals wear areas to reduce the risk of binding and help protect against future wear.
- Hardcoat anodized aluminum piston combats premature wear
- Improved spring design and upgraded material increases strength and resiliency
- O-Ring seals against separator plate to prevent leaks
- Drop-in Zip Valve® parts install quickly and easily
Symptoms
- Delayed converter charge
- Poor converter fill & delayed engagements
Cause
Bore wear around the relief piston can allow the piston to bind and converter fluid to drain out of the torque converter line when the engine is off.
Correction
