IMO I'd do the tranny/diff every two years/24,000 miles. Coolant every 2-3 years (and use distilled water with the Dex-Clog).

[anecdote mode]
Back when I was in high school (~12-13 years ago) I worked at a Minit-Lube and we had a guy come in with a '66 El Camino (as I recall). It was our practice to check the rear diff, etc., and this guy's rear diff fluid looked like curdled milk. I asked him when was the last time he'd had it changed and he said "never". To make matters worse he'd owned the car since it was new! <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> Of course he decided that it wasn't necessary to have it changed. I believe his comment was "they've been together this long, why change it now". Amazing, some people... <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> [/anecdote mode]

I use Mobil 1 Synthetic ATF.. I changed mine the second i bought the car, but i bought my car with 30k miles on it. I work @ a Lexus Dealership as a tech, we change diff and tranny every 15k. And coolant every 30k. Seems to work out good.. People with the M6 shouldnt need to change as often, but whats 30 bucks every 15k to make sure your car will be in one peice after that 1/4 mile run...

There is only one kinf of Mobil1 Sythetic ATF anyway... For the rear diff i used RedLine Synthetic gear lube, 75w140 i think.. And i run Mobil 1 5x30 in my engine. Im **** about synthetics.. i even flushed my power steering to replace it with mobil 1 synthetic PS fluid. Hmm.. maybe DOT5 brake fluid next! Woo!!!

I change my diff. and trans. fluid once a year since I do a lot of drag racing. I figure I'll be doing another cam swap before the coolant needs changing, so it stays fresh. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
