He bought a 2000 Dakota Sport 4WD with all of 55,000 miles on it. It has a leaking front main seal, axle seals, some ugly faux "ram air" intakes glued to the hood, etc. It looks like some guy bought it to haul around a dirt bike and party with. We just pulled all of the wiring from his old bass system out. We took the whole interior apart tonight and replaced all of the broken clips and cleaned it out. He has done the plugs (Champion Double Platinum), changed the oil, checked air filter. The transmission, transfer case and differentials were done just before we bought it. It starts and runs good, tons of power, but an absolute pig on fuel. 19 mpg flat land cruising with the AC off. I was wondering: - Any mileage ideas? Obviously it'd probably be smaller tires (has 31x10.5x15 tires), and swap the 3.92 gears for 3.55 or 3.21. - Can I get a UOA that would tell me for sure the fluid in the transmission is ATF+4? It shifts too soft and I don't want to see a transmission get burned up on the wrong fluid. - Any trouble spots to look at? It drives fine other than needing front shocks, but it looks like anything plastic has seen hard use.
