How many miles does your original Vortec V6 have?
#58
2002 with the original 4.3L engine, original 4L60E trans & original rear axle. Never had any of them apart other than to change fluids and a set of felpro intake gaskets. Had 120,000 mostly city driving, then it saw 350 miles a day 5 days a week for 5 years. Retired it back to city driving a couple of years ago with just over 375,000. Still going strong, doesn't leak or burn oil, no noises. Regular maintenance every 3,000 miles, what ever it needs. Oil & filter every other weekend. Trans fluid & filter every 36,000. You take care of them, they'll take care of you
