*Add an auxiliary transmission cooler. Pick a core up at a junkyard for $5-15usd, two 5/16" brass T fittings, 8 small hose clamps, zip ties, 5/16" oil hose.
*Flush the transmission fluid every other year, or drain the pan every other oil change.
*Change the oil every 5,000miles - 6 months for dino oil, 7500-10,000 miles - 10 months for good synthetics.
*Clean oil pan & screen, transmission pan & screen & change transmission filter every 5 years.
*Rotate tires every oil change, twice if you're using a long life synthetic.
*Clean the inside of the upper portion of the intake manifold, throttle plate, ISC/IAC valve(idle valve), and EGR valve yearly.
*Change differential fluid every four years.
*Flush the brake system with fresh dot3, dot4, or dot4+/Dot5.1 every three years.
*Change the fluid in the power steering reservoir every year, or flush the power steering system every other year.
*Flush the cooling system every other year, or drain yearly.
*Change radiator cap<s> & thermostat every 5 years.
*Change PCV valve every 5 years.
*Change o2 sensor<s> before 100,000 miles accumulates.
*Change cat convertor before 100,000 miles accumulates.
*Change distributor cap & rotor every other spark plug change (120,000 miles).
*Check belts yearly, change belts when needed, change all belts (including timing belt) every 90,000 miles. Replace the water pump every other timing belt change.
Otherwise, just keep track of things. Like CV boots, things you need to grease, seals that can leak etc.
*Use only NGK, or Denso spark plugs. Might as well be the generic $1 versions, as they last over the specified change time.
*If spark plug wires ever become damaged, only replace with OEM wires, or high quality wires.
