46RE / 46RH / 47RE / 47RH / 48RE Piston Retainer Kit, Sonnax 22754N-01K.

Many OE supports in Chrysler 46RE / 46RH / 47RE / 47RH / 48RE units do not seal well against the case which leads to reduced lube flow to the gear train and consumption of pump volume. Additionally, Sonnax piston retainer kit 22754N-01K maximizes gear train durability by preventing the loss of lube oil between support and case.

  • This unique design features two sets of I.D. and O.D. grooves repositioned at key load areas to improve oil delivery
  • O-Ring improves case seal and prevents loss of lube oil
  • High-quality aluminum alloy resists gauling for better wear resistance
  • This kit includes two optional plugs for use in RE unit


  • Loss of lubrication oil to planetaries
  • Reverse drum, retainer and planet failure

The 46RE / 46RH / 47RE / 47RH / 48RE Piston Retainer Kit (Sonnax 22754N-01K) Includes:

  • Piston Retainer
  • O-Ring
  • Plugs (2)


Excessive clearance between the overdrive piston retainer and intermediate shaft reduces lube flow to the gear train.


Restore lube oil and prevent repeat failure by installing Sonnax piston retainer kit.
