My 69 Chevy power glide will not go in passing gear and it shifts to soon about 10 miles hour and I made sure that you had full throttle and full tv range at the transmission?

Make sure the downshift linkage from the carburater is connected and adjusted properly. Also, some vehiles of that era had "vacuum modulators" which can go bad and cause a little trouble.

What does the tow load button do on a Chevy truck?
The tow/haul button on the later model GM trucks and SUV's change the shift points in the transmission. While accelerating it raises the RPM's for the shift points and it raises the line pressure in the transmission for firmer shifts. When passing it changes the throttle position for the downshift from 3/4 throttle to 1/2 throttle so the transmission downshifts sooner into the lower gear. When slowing down it downshifts sooner throughout the gears back to first so if you have to speed back up you are already in a lower gear.
