Reverse Servo Piston Plug
Price: $41.18
Part Number: TAT-22912-01K-SX
There are two styles of the OEM reverse servo piston plug in Chrysler RWD units: the extended tip version for the 47RH/RE (A618) and 48RE, and the flat tip version for the 40RH, 42RH/RE, 44RE (A500), 46RH/RE (A518), 36RH, 37RH (A727) and 30RH (A904). Both versions of these OEM aluminum plugs are subject to wear, galling, and breaking at the spring seat area due to high stresses in reverse. The Sonnax replacement plug 22912-01K can be configured to work in both OE applications, and has been manufactured from hardened steel to more than double the tensile strength of the part.

Features & Benefits

Plug is machined from wear-resistant hardened steel with more than double the tensile strength of the OEM part.
A larger radius is provided at the spring seat area to minimize the primary stress riser and prevent breakage.
2-for-1 design works in all applications, with minimal modification.
O-ring added to seal between the plug and the piston eliminates leakage of servo apply oil.
Replacement heavy-duty retaining ring included in kit.
