Well, I finally got around to it, Converter Clutch (TCC) not engaging, OD light flashing, code reads "P1744, TCC Sol. Ckt. Error or stuck OFF". I measured sol. coil resistance at 10 ohms, Ford Shop Manual specifies 9-16, resistance to ground infinite, so sol. coil electrically OK.
Manual says Torque Converter Drain Plug "If Equipped". With 4.0L SOHC engine, no way to access torque converter outer circumference, where plug is shown, if equipped. I cut a silver-dollar-sized hole in the bottom of the converter housing with a hole saw, turned engine by hand, no drain plug exists.
First Question: How effective is filling/running/draining/ re-filling with fluid several times, at clearing out 100K mile oil out of the converter?
Second Question: If a hole were carefully drilled in the bottom of the outer periphery of the converter, then threaded for 1/8" pipe plug, would the draining oil remove any chips introduced? Would a Loctited plug loosen in service? Cannot tell in Manual what type of plug they used, when they did, if a pipe plug, or flat with seal. Would a steel 1/8" flush hex socket plug introduce unacceptable vibration?
Third Question: Am I nuts for asking No. 2?
Finally, is there any way of actually checking the solenoid after removal from the transmission for movement of it's armature? Do they click audibly if 12V. applied? Would the click necessarily mean sufficient movement of plunger is occurring?
Any thoughts would be appreciated! imp
