Allison 1000 Oversize Gain Valve Kit Sonnax Part Number 37000-24K Fits 2000–2009 units only.

“A” and “B” gain valves in Allison 1000 / 2000 / 2400 units (2000–2009) control activation, release and holding pressures for the five clutches in the unit. When the “A” or “B” gain valves, or their bores wear, the control main pressure and reverse signal pressure can cross leak and equalize, preventing proper clutch control. Additionally, wear can permit Reverse signal pressure to escape to exhaust resulting in runaway trim pressure. These conditons lead to shift issues associated with circuit pressure loss. Sonnax oversize gain valve kit 37000-24K corrects shift concerns associated with circuit pressure loss by replacing the worn OE gain valve in both the “A” and “B” gain bores, restoring OE gain valve response and normal “A” and “B” trim signal pressure. 

  • Hardcoat anodized aluminum valves combat premature wear
  • Oversized “A” gain valve designed to utilize OE “A” gain spring

  • Gain Valves (2)
  • O-Ring

Description

Allison 1000 Oversized Gain Valve Kit Sonnax Part Number 37000-24K Fits 2000–2009 units only.

Warning: “A” and “B” trim pressure valve trains are visually similar but are not the same.

Symptoms:

  • Shift concerns associated with circuit pressure loss

Cause:

Valve spools and bore wear due to continuous valve oscillation. Degraded valve/bore clearance allows critical hydraulic pressure to escape to exhaust or cross leak to adjacent circuits, and may cause the valve to stick.

Correction:

Restore proper hydraulic control by refurbishing the bore and replacing worn parts with the oversized Sonnax valve kit.

Tool Needed: F-37000-TL24
