Have you had the tranny serviced and if 4WD the transfercase?
2003 Suburban 5.3 Tune-up-What all do I need?
Plugs
TB/MAF cleaner
Fuel filter
Air filter
All that stuff I know, but is there anything else? It has 136,000 miles, is there anything else I should do at this mileage? Don't kill me for this, but it has never had a tune up... But it had a coolant flush and fill with a water pump replacement at about 80k miles, and that's all the work it's ever had. (Bought it new)
