Quick Overview

SONNAX REAR 47RE 48RE SERVO PISTON, 1997 UP 22912C

Details

Many Chrysler A727, 42-46-47RH/RE, 48RE and A904 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, inhibiting band apply. 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 billet aluminum pistons 22912,
22912A, 22912B and 22912C to address these problems.
