In listed Chrysler transmissions it is common to have the accumulator bores scuffed and worn due to the rubbing action of the seals. This creates a poor seal resulting in drivability complaints of shudder or slide shifts. Sonnax offers two accumulator bore sleeve and piston kits, 92834-03K and 92834-05K, that re-establish hydraulic integrity and save valuable cases and valve bodies.

  • Kits salvage valve bodies or cases with worn alumimum bores.
  • Sleeves are made from carbon steel that will resist scuffing and wear.
  • The piston included in the kits has two scarf-cut PTFE seals with graphite filler to prevent cross leakage.
  • The 92834-03K kit reuses the OE springs which, with the reduced replacement piston diameter, will provide shorter than factory shifts. The 92834-05K includes two custom springs designed to work with the replacement piston in restoring OE-style shifts.
  • Both kits can be used in the underdrive, overdrive, low/reverse, or 2-4 accumulator bores.
