The truck is a 2001 automatic pretty much stock.
I when throught the same whoo ha on my 7.3. It would drop out of 0d into 2nd and not take 3rd. The solenoid pack was replaced and I had the same problem again.
Need more details on exactly what it is doing and mods?
I found my PCM had failed after spending $XXXX on the transmission. If the PCM fails it will prevent the transmission from staying in OD and will failsafe to 2nd. It will have 1,2, R but no 3 or OD. Mine would work for 20 miles or so then when hot fail out of OD into 2nd.
Do the normal checks on the coil pack as per Ford manual. It might also be the selector switch failing on the side of the transmission.
Don't be in too big hurry to change the coil pack. I am not saying it isn't the coils but they are very reliable and other compenents will cause the same problem.
Best of luck you really need a GOOD shop to help diagnose. For me I had the best tranny guy within 300 miles. Everyone kept saying If you would have bought a.......... But the problem was not the transmission but an external component.
