I have a 98 sport sohc and I have a problem with 4low not disengaging. It will shift into 4 high and out without a problem and also into 4 low but it is very hard to disengage 4 low. I tried going forward a little and reverse a little then putting it in neutral but it still wouldnt disengage. I finally tried putting it in neutral and putting the switch to 4auto and then turning the truck off and on and it disengaged. I was wondering if anyone has any suggestions on what the problem could be.
