Hi all, first time posting on this site. I want to convert my Comanche to Mercedes om617/auto. I bought the Mercedes engine/trans assembly already bolted together. After researching options it looks the easiest and cheapest option is to remove the 2.5/auto and install the Mercedes diesel and auto. The Comanche will be used to haul tools and equipment to job sites. Airbags for the rear, bed cover/camper top and a pull out tool tray in the bed will be used. Kit to install Dakota oil pan to allow engine to sit low instead of installing suspension lift as Comanche will be used primarily on the street and I prefer a low center of gravity. Anyone ever use the Mercedes auto in a Jeep?
