Toyota Repair: Recommended Maintenance +100K Miles, oil leaks, toyota corolla

Question
I have a 1989 Toyota Corolla 4 cyl automatic that I bought used from a private owner about 18 mos ago. It had 99k miles on it when I bought it and now it has 115k miles. I do the regular stuff (oil changes every 3K miles, check fluids, rotate tires, etc).  From the maintenance records I got from the prior owner, it appears that all the scheduled maintenance was done when it needed to be. My question is: after 100K miles, is there a schedule of recommended services or things to check? If there isn't, what would you recommend that I keep track of and check so that my car will keep running to 200k and beyond.

Answer
Other than regular maintenance and checking wear and tear items like brakes and the CV joint boots and oil leaks which can develop at higher mileage, I would recommend checking the timing belt, it should be replaced every 60,000 miles.
It is also very important to keep the transmission fluid clean change ATF at least every 30,000 miles or once a year.
