Bypass Clutch Control Plunger Valve Kit
Part No. 76948-04K
- Plunger Valve
Too much oil to the bypass control valve plunger, or wear at the control sleeve.
The smaller orifice in the Sonnax sleeve allows TCC oil to stroke the bypass valve more quickly. The improved plunger and sleeve replace worn components that are leaking converter charge oil to exhaust.
