Description
Allison 1000 / 2000 / 2400 Oversized Manual Valve Kit, Sonnax 37000-28K.
Fits ’00–’15 units only.
Tooling:
- F-37000-TL28
- VB-FIX
In ’00–’15 Allison® 1000 / 2000 / 2400 units, wear within the manual valve bore can cause reduced line pressure, the symptoms of which are delayed Forward and/or Reverse engagement. Severity and location of wear along the manual valve bore dictates the specific symptom. Regardless of wear location, once fluid pressure leakage due to wear affects the time required to build sufficient actuating pressure within a circuit, delayed engagement is the result.
Sonnax oversized manual valve kit 37000-28K can eliminate escaping oil restoring hydraulic control to the circuits routed through the manual valve bore.
- Hardcoat anodized aluminum valve combats premature wear
- Additional annular grooves added to reduce wear rate
- Valve
- Selector Pin
Symptoms:
- Low line pressure
- Delayed Drive
- Delayed Reverse
Cause:
The worn manual valve bore or spools allows function-critical hydraulic pressure to escape directly to sump and/or adjacent circuits, exhibiting low line pressure and related engagement delays.
Correction:
Restore critical hydraulic control by refurbishing the worn bore with the Sonnax tool kit and installing the Allison 1000 Valve Kit.
