How often should you change synthetic tranny fluid?
I just bought a 1972 250C last week. It's the first car I've owned with an automatic transmission since I was 16 years old, so I'm a little ignorant about maintenance intervals for automatics.
Going through the receipts that came with the car, the previous owner drove the car regularly, but he didn't put very many miles on it. As a result, the last tranny flush & fill was a little over three years ago, but only 3,000 miles ago. The shop used Redline synthetic ATF for the fill.
The owner's manual lists a service interval of 30,000 miles for the transmission fluid, but I don't know if there's a "time limit" for the fluid as well, or if the service interval is longer when using synthetic fluid.
So, with modern synthetic fluid and regular driving (12-15,000 miles per year), what should I be looking at as far as tranny fluid service intervals?
