Kit, End Plug, Kickdown Control, No O-Rings, 4R44E, 4R55E, 5R44E, 5R55E, Ford (95-UP)

The end plugs at the kick downshift control, manual low, and throttle downshift control valves become loose. This allows solenoid feed oil to exhaust and drop below 40-45 psi, which prevents the shift valves from stroking fully. The Sonnax kit 37947-13K contains o-ringed end plugs for these three locations, which positively seal the circuit to prevent oil loss.
