In vehicles with a 4L60 & 4L60-E transmission, servo apply areas often need to be increased to improve 1-2 shift. This is often done by replacing the 2nd servo piston assembly, typically with the #553 version. This practice has caused an overabundance of used #554 servo assemblies and poor availability of quality #553 assemblies. Sonnax offers a 2nd Apply Servo Saver Sleeve, 77911-01, that salvages used #554 assemblies by allowing conversion of the #554 piston assembly into a #553 version. The sleeve is pressed into the existing #554 inner housing.
