This affects converter charge at idle, causing engine stumble, loss of lube oil flow, overheating and poor performance. Bore wear at the inboard end creates poor TCC apply or a reduction in line pressure boost.  If the bore is not excessively worn, install Sonnax standard OE-size switch valve kit 22771A-01. Both the oversized and standard size Sonnax valves will improve the timing and flow to the apply and release circuits.Valve controls TCC release oil venting during apply for a firmer apply and no shudder.Stem length, spool spacing and exhaust timing have been improved to ensure quicker stroke and less valve bounce.Salvages worn bores.NoteThese kits can only be used to replace 4-spool design or OE valves or bore repair with OE 4-spool design.No tooling required for direct replacementParts ship daily from our distribution center.GOT QUESTIONS on your specific Year/Make/Model?  Send us a message ¿Habla español?
