I'm not an auto guy but from what I read the tach has to work for the E4OD to shift right. Replace the tach sensor, a ford only item. It is located behind the oil fill tube on the timing gear housing, a threaded tube with a big nut on it with two wires coming out of it

Old post.....
Hold the phone... I just ran into this problem...
Pull the TECA POWER RELAY, (Transmission Electronic Control Assembly) this is the relay that supplies power to the PCM (Powertrain Control Module). That relay is toast. It's located on the drivers side fender well just behind the windshield washer fuild reservoiur.
I made a post about this about 2 months back or so, what caught my eye was the DIM OD LIGHT and LOSS OF GEARS. Yank that relay and clean the plug, toss relay over shoulder install new one. If you have the trailer tow relay you can put it in place of the TECA PWR Relay, the relays are the same.
