Kent‑Moore Tool Number: J‑43911(Discontinued)

The Allison ATT‑43911‑A Shift Lever Seal Remover is a precision‑engineered specialty tool designed for servicing Allison 1000/2000 Series and B‑Series medium‑duty transmissions. This tool allows technicians to remove the selector shaft seal without removing the transmission from the vehicle, dramatically reducing labor time and simplifying maintenance procedures.

Built to OEM specifications, the ATT‑43911‑A features a 3/8"-16 shaft end and a tapered buttress thread (.510"/.505") that securely engages the selector shaft seal for controlled, damage‑free extraction.

✔ Specifications

  • Application: Allison 1000/2000 Series & B‑Series medium‑duty truck transmissions
  • Purpose: Removes selector shaft seal while transmission remains installed
  • Shaft End: 3/8"-16
  • Thread Type: Tapered buttress thread (.510"/.505")
  • OEM Equivalent: Kent‑Moore J‑43911

✔ Instructions for Use

  1. Position the ATT‑43911‑A over the selector shaft.
  2. Tap lightly to engage the tapered buttress thread into the outer lip of the seal.
  3. Turn the body approximately 1/4 turn to fully engage.
  4. Tighten the screw against the selector shaft to draw the seal out of its bore.

This method ensures efficient, controlled seal removal without transmission removal, preventing unnecessary downtime and reducing the risk of component damage.
