2004 lb7 duramax. Engine runs good but the transmission started shifting hard so I parked it with the intension of rebuilding the transmission but I don't have the time and just need it gone. Also the last time I started it it started leaking coolant out of the thermostat housing somewhere. it has a airdog lift pump, brand new one piece drive shaft, kryptonite upper arms and tie rods, 4 inch straight pipe, gooseneck ball in the bed and airbags.
