Sounds like your cycling pressure switch is cycling because of a low refrigerant charge. Have you put the gauges on it? Do you have any R12?
I drive an '89 4.3 S10 100 miles ever day & this has been the absolute most labor intensive vehicle I have ever owned! It had 99K miles on it when I got it home (Not running of course) & I've put 35K miles on it.
I've seen just about everthing an S10 can pull.
Oh & your trans should be a 700R4 like mine.
