Transmission crossmember change to auto. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The tricky answer is yes.

You can bolt in the crossmember to hold an automatic up by the tailshaft, without pulling the cab off.

However (and here's the trick) removing the crossmember that holds the bellhousing for the 3-speed (which gets in the way of installing the automatic) will be difficult without removing the cab, unless you have an air chisel for the rivets. Getting at the top ones with a drill would involve going at them at an angle, and I shudder to think about doing them with a hand chisel and hammer.
