Well, this is some big news that will interest all the Jeep Wrangler fans out there. JLWranglerForums has received a scoop on the pricing of the diesel engine option. As it turns out, the famed 3.0-liter EcoDiesel engine will be available as optional on the 2020 Jeep Wrangler JL for $6,000. This includes the price of the eight-speed automatic gearbox as well. But theres a catch. Although the premise of this engine making its way under the hood of the Wrangler is exciting at the onset, we are utterly disappointed that this engine cannot be mated to a manual transmission. Come on, Jeep. Why cant you let us have the cake and eat it too this one time?
