The OE manual valve in Ford 5R110W units is prone to anodization flaking and degradation resulting in premature wear of the valve and loss of hydraulic control. Sonnax oversized manual valve 36940-11 outperforms the OE valve.

  • Salvages valuable valve bodies
  • Restores OE manual valve function
  • Sonnax hardcoat anodized aluminum valve maintains tight bore/valve clearances after thermal expansion and combats premature wear

A visual inspection indicates wear at the low/reverse clutch circuits (the land between the two most outboard circuits), or wear at the line pressure/direct clutch circuits (the land between the two most inboard circuits). Obvious wear of the valve spools at the locations discussed above indicates wear in the bore.
