thinking about buying a medium duty truck with an Allison 2200 trans. How good is this trans? Will it handle more hp and torque than their website says. For instance their website say the one in the chevy pickup (1000) will only handle 550 lbs of torque. I am real sure there is someone here who has chipped and run a higher flow exhaust, and is making more torque than the allison site has said. How is it holding up? I am trying to find out how tough these 2200 trans are. Please help I am in limbo on that cause I am going to chip the truck and cut the exhaust off so WILL the 2200 hold up? Thanks in advance.
