and if so where could i find one?

does your module at least make a clicking noise when you push the button?

it could also be the speed sensor. The speed sensor will allow shift on the fly into 4hi, but you must be stopped in order to engage 4lo. Are you trying to put it in 4lo with the truck in neutral and foot on the brake (if it's auto)
you might also try swapping out the switch to rule that out as the problem.

It may be the speed sensor, here's a diagram that may help
Install the brown clutch coil wire to the No. 1 center terminal and, if removed the speed sensor green wire to the No. 4 connector position and the blue wire to the No. 5 connector position.
