I have a 2000 f 150 4x4 I am trying to find out how hard it would be to put a 2 wheel drive transmission in as I already have a 2 wheel drive transmission and the drive shaft and wire harness setting here from my old truck 99 F 150 I know the transmission will match up as I have already used the motor but don't have the money right now to get another 4x4 transmission as the transfer case is bad too what all would I need out of the 99 to make this work as I know their are 2 sensors on the transfer case that are not on the 2wd transmission
