Description

4R100 / E4OD Heavy Duty Low/Reverse Modulator Sleeve Kit, Sonnax 36947-09K. 

Fits ’96-later units, uses higher OE ratio

In Ford 4R100 and E4OD units, the holding capacity of even the largest modulator plunger valve assembly does not supply enough line pressure to the low/reverse clutch to adequately hold the clutch in diesel or heavy-duty applications. This same issue will occur in gas applications as the vehicle ages at multiple locations continues to rob line pressure.

Sonnax heavy duty low/reverse modulator sleeve kit 36947-09K is an innovative, dual-plunger valve drop-in replacement assembly that prevents repeated low/reverse clutch distress and burn-up. The inboard, smaller plunger valve has the ratio of the larger OE plunger valve, but functions primarily as the engagement control for the low/reverse clutch. A small orifice along the valve axis prevents harsh or bang engagements by maintaining a controlled feed flow to the larger, outboard holding valve. This valve provides almost double the holding capacity to the low/reverse clutch as the OE valve.

  • Innovative dual-valve design controls clutch engagement while nearly doubling holding capacity
  • Hardcoat anodized aluminum valves combat premature wear
  • Newly designed sleeve made from highly wear-resistant aluminum alloy
  • Drop-in Zip Valve parts install quickly and easily
