Excessive valve-to-bore clearance at the modulating pressure area allows modulated solenoid feed pressure to exhaust, reducing line pressure and creating shift-related complaints. Sonnax outer pressure regulator sleeve 68942-06 salvages the valve body with a precision-machined, wear-resistant aluminum sleeve.

Note

Repairs outer bore only; see 68942-07K for full bore repair
