I read up using the 1954 Chevrolet Truck Shop Manual link above. It says I will be lifting the 3 speed trans out thru the floor, I was expecting to lower it down from the bottom based on my past jobs although this is my first AD trans removal for me. Is that the correct way?
The transmission is too long to fit thru the floor opening without tipping it on end. The best way is to use a hoist thru the door and lower it to the ground thru the floor opening. Second best is use a transmission jack to support it from below. Or just bench press it from below.
