loved the 5.13's, it was an auto. I bought it as a trade in here at the dealership, the original owner picked it up from jeep and took it straight to get the lift and wheels tires, drove out of that shop and did not like it, turned around and had the gears done, still did not like it so did intake, exhaust and chip, bumpers. It towed the boat ok, took a bit to get up to speed and had to drive very carefully, the boat has excellent brakes so that helped but you could feel it "moving" at 65+ loved the jeep but needed a better tow vehicle for the boat and my rock crawler, so ended up with a mega cab diesel 4x4 lifted.
