Hi, this vehicle is 2WD and does not have a transfer case. It is still fine working with the original waterpump. Hope that helps you.

What items did you replace outside of spark plugs, brake pads, rotors, filters, oil (motor & trans) and coolant?
 
I’m due to hit the 200k mile club shortly as well! I have a 2010 GT AWD and have been changing the transfer case fluid with every oil change. It’s a pain in the rear but it’s still hanging in there. The water pump is still working as well. I frequently check the temperature gauge and check the oil to make sure it’s not turning into a milkshake.

She is starting to show her age and I’ve fixed a few problems which cropped up around 190k. Fortunately everything was very cheap to fix:

- Greased the starter bendix shaft to stop the occasional screech on cold starts
- Patched a few small exhaust leaks around the muffler from where the rear heat shield brackets rusted out
- Replaced the radiator drain plug which disintegrated and started dripping coolant
- Replaced the brake booster which failed at 196k, I got a replacement from a salvage yard for $45.

Otherwise everything is still original, with the exception of the obvious wear components such as brakes, tires, suspension components, bulbs, fluids, battery, filters, spark plugs, etc. I include suspension components as wear items as I often drive on extremely bumpy (and often unpaved) roads for work, so the suspension experiences way more wear than your average driver.

I’ve also had a torque converter shudder since ~120k miles which is kept in check with a single ATF drain/fill with shudder fix additive every other oil change.

While she has been needing a bit more TLC lately, the performance and handling is still excellent and I plan on keeping the car until the wheels proverbially fall off.
