Symptoms:
  • Delayed engagement
  • Flare shifts
  • Harsh shifts
Cause:

Scored accumulator bores create loss of clutch pressure or cross leaks.

Correction:

The accumulator bore sleeves are made from wear-resistant aluminum and the length of the piston-to-pin contact area has been increased to reduce piston cocking and increase sealing surface area.

1-2 Accumulator

Complaint:

  • Delayed engagement
  • Flare shifts
  • Harsh shifts

Cause:

Scored accumulator bores create loss of clutch pressure or cross leaks.


Correction:

The accumulator bore sleeves are made from wear-resistant aluminum and the length of the piston-to-pin contact area has been increased to reduce piston cocking and increase sealing surface area.

The accumulator bores on AXOD & E, AX4S channel castings can become scored, which creates loss of clutch pressure or cross leaks. The continuous oscillation of the piston within the bore causes excessive wear. Also a broken accumulator spring can get caught between the piston and the bore causing a deep groove in the casting wall. You can resolve these problems by installing these Sonnax AXOD & E, AX4S accumulator bore sleeve kits.

  • Kits contain an aluminum sleeve and new steel accumulator piston with a Viton® O-ring.
  • Piston is compatible with all OE springs and OE piston pins.
  • Length of piston-to-pin contact area has been increased to reduce piston cocking and increase sealing surface area.
  • Kits available for N-D, 1-2 and 3-4 locations, along with a master kit that contains all three.
