I have a 93 chevy k1500 with a 9 inch suspension and a 3 inch body lift with 38 inch tires on it with a 355 motor in it and yesterday i was just cruising around 55 and it popped out of 2wd and went into nuetral....it did it another time to. The pavement was dry and nothing out of the ordinary was going on. Any ideas of what this could be?
How do you go about a band adjustment, the trannys been redone and prolly only has 50000 miles on it now.
