Ford 6R140 Valve Body Identification Guide

The F06R140 incorporates updates that allow it to be used to replace both early- and middle-style variations of the 6R140 that use a cooler bypass valve. Sonnax does not currently offer a replacement valve body for late-style units with a blocked cooler bypass valve.
