A defective (open circuit) resistor can cause binding at low speed as removing it will effectively cancel out the line pressure reducing action of the transmission control computer as done by solenoid A under some driving conditions including below about 15% throttle opening. Line pressure will be higher than intended and therefore the duty of the transfer solenoid will not translate to the intended amount of apply to the transfer clutch (too much apply) which will cause the binding effect, which should be noticeable if your transfer clutch is in good operating condition. I suspect this will surprise some as the earlier transmissions' sealing rings literally wore grooves in the aluminum extension housing and transfer clutch pressure will leak past them, and that might be enough to alleviate binding when the resistor is unplugged.
