I have a 1997 and it is up under the front air dam flap, which someone sliced to get at the filter and right of middle a bit.
I recommend using nothing but either Mobil 1 or Amsoil - they are the two best commercial synthetics. I get an extra 1mpg using synthetic engine oil and another 2 mpg better when using Mobil 1 ATF. I change my engine oil at least twice a year or if it gets dirty or every 7500 miles. I only change the oil filter every second time.
I change tranny oil every 36,000 miles - only replacing what comes out of the pan - not the torque converter. That is about 7-8 liters.
I use Mobil 1 ATF in the power steering, too. I had a power steering oil leak that made my pump whine. I changed the oil by pumping it out and filling it back up with Mobil 1 ATF. The pump stopped making the noise, and I eventually fixed the leak.
