Vehicles with an AXOD & E or AX4S transmission frequently have lube system failures, as well as torque converter clutch apply and release problems. These complaints can be aggravated by severe wear of the bypass clutch control plunger sleeve. Excess wear allows regulated converter charge and cooler oil leakage. This oil is fed to the lube circuits, cooler, TCC and into the sleeve to help maintain the TCC in the release position. If the sleeve is worn, oil will exhaust past the plunger sleeve. Because this regulated converter charge oil is always present, either as release or apply pressure, severe leakage at the sleeve can result in a no TCC apply situation. Sonnax offers a tightly toleranced bypass clutch control sleeve and plunger valve, 96206-01K, that restores hydraulic integrity and eliminates the above problems.

  • Precision sleeve is manufactured from high-quality aluminum to minimize wear.
  • Aluminum plunger valve has been hard-coat anodized to resist wear.
  • Sleeve has been lengthened to prevent oil loss.
