Check all fuses
Can you try removing the shift motor from the new 4406e t case.
Try shifting it into LOW and see if the motor moves.
With the truck in N see if you can shift the t case into low range manually (pliers or vise grips)
Put the truck in N and see if it will start? If the truck does not start in N then you need to adjust the NSS on the side of the trans
I am pretty sure the GEM module in a 2000 Ranger is what controls the 4wd switching.
We may need to compare some wiring charts here from 2000 ranger to 2000 explorer, the Gem module may not know you are in N thus stopping the low range shift....
It's quite possible your Gem module is not happy with the new transmission/conversion, lets start with the basics. Fuses, relays and testing at the t case itself
Is the check engine light on? Do you have any codes aside from the low range codes?
If not codes I would start by checking spark plugs and wires. The 5.0L eats cheap or old plug wires
Next would be looking at the conversion itself, and running some drive cycles, then pulling codes. Do you have the ability to monitor live data?
Any intake leaks? Any missing vacuum lines? What is fuel rail pressure?
It has no other codes. Isn't running lean or rich. Plugs and wires are new, Motorcraft. I was thinking it was a GEM issue, but I have talked to guys that have done this swap and they all say it is plug and play
Truck starts in neutral
