It depends on how much money you could go to nv4500 4l80e th400 the nv4500 will be the most money and pane it is a heavy duty 5 speed but stay away form a nv 3500 it you beat the truck and have big wheels and if you go with the 4l80e or th400 new drive shafts frunt and back 4l80e will need a controller 400 you will need to swap gears in the rear end probly to something taller for half way good hyway speedSo I have a 1994 k2500 light duty with a tbi 305 and 4l60e, and I eventually want to swap to a 350 but haven't decided on what tranny to do. So I was wondering what are my best options? I don't want anything crazy hard but I don't care if it's manual or auto.
