C6 longevity question

I have almost 100K miles on a '89 C6.

Questions:

How many miles can I expect to get out of this tranny?

How often should I change the fluid in it?

fluid I would change every 60,000 miles, and the miles you get out of a c-6? that just depends on how hard you are on it. lol

I've heard of C6's hitting 300,000. Mine, even behind a big block, has at least 170,000 on it right now, depending on how many times the odometer has rolled. Keeping the fluid fresh and under 200 degrees will let them live a long time.
