2004 Chevrolet Silverado 3500

Selling my 2004 Chevy Silverado 3500 LT 4x4 6.6 Turbo Diesel. Bought it in 2023 thought I was going to make it a welding truck but have different plans. Not in a rush at all to sell, just tired of it sitting. Have few codes about transmission. I have a problem starting it, you have to retry several times before anything pops up. Almost certain it’s something to do with wiring because everything I’ve traced shouldn’t be an issue. Also drips a bit of oil from the oil drain tube from the turbo I replaced. I must of not gotten all the gunk or something between the gasket but bolts are tightened most I’m capable of( about 1/4 of a quart every 2-3 weeks). Just replaced the whole front end besides lower control arms and shocks just waiting on income to replace it. Rear tires will need replaced soon. 242,835 miles on the truck. Have title in hand. Also not fully detailed just taking my time cleaning it. Will need alignment after tires. For a 21 year old truck she just needs some cosmetic loving. Usually 1 heated seat works at a time. Ac is ice cold. Heat is hot as mars. Temps stay perfect really never had an issue besides the transmission problems. Every once and while when the codes run she’ll be hard to shift and take forever. Typically if you shut it off and turn it back on it’s back to normal. Has a 5th wheel plate made by the previous owner in the bed. Hitch is a little bent from previous owner never really had interest in fixing because never had an issue towing.
