TransTec announced that all of its Ford E40D/4100 overhaul kits (model years 1996 and up) will contain Direct and Intermediate Feed Tube Seals.
The company notes that due to case and support wear, some transmissions may exhibit a fluid pressure loss in the direct and intermediate clutch feed circuit, causing premature clutch failure. According to TransTec, this solution seals the gap between the case assembly and the center support preventing that loss in pressure. Each seal is also spring-loaded.
