Product Details
(Servo Pison Only). Many Chrysler A618, 47RH, 47RE transmissions experience rear servo piston sticking/breakage, pin bore wear, and reverse band slippage. The servo piston has a tendency to get cocked in the bore there is insufficient force to apply the band in a direct line. The high reverse line pressure continues to apply against a cocked piston, causing piston breakage. The bore of the piston also wears from side loading, resulting in insufficient band apply pressure. Sonnax has developed a billet aluminum pistons, 22912B to resist breakage better than the original cast pistons. The seal ridges on the pistons have also been rounded to prevent the piston from sticking in the case bore. The lower piston seal ridge has been made slightly smaller to prevent sticking.
