Some time in the late '70s the buyers of light trucks learned the auto trans, with the amplification of the torque converter would match the load starting ability of the "granny low" 4 speed. And without needing to worry about the driver's skill level on clutch engagement and the first shift, they started giving the auto higher GCVWR.
The GMC I posted about was not a pickup, but twin screw. Had a 5 speed main, and a 4 sp auxiliary transmission.
The automatic needing no skill likely killed off the granny gear.
Add in the proliferation of 4x4 trucks with low range effectively creating a granny gear if you needed one helped the process along.
