Auto transmission.
Since the real history of a used car is questionable, why not just change it.

FYI, for your 06 auto AMSOIL recommends their low viscosity ATF which is their version of Dexron VI:
AMSOIL Low Viscosity Universal Automatic Transmission Fluid (ATL) (Product Code ATLQT)
I'm more than happy to get this for you at dealer cost, about 25% below retail via the AMSOIL Preferred Customer Program if you decide to go with AMSOIL.

one more thing if under 50,000 miles change it. NOW
most who wait for 100,000 have problems and need a rebuild

as the new fluid cleans things up.
if you change before 50,000 it doesn't seem to do that

One more thing (which doesn't apply to your '06 with the older warranty), the Amsoil ATL is not on GM's list of licensed Dexron VI suppliers and is not held to the full Dexron VI specifications.

Using Amsoil ATL in your '07-'11 Corvette A6 will void your warranty with GM leaving Amsoil as your only recourse to pay for repairs. Amsoil may say it meets the specs but it is not licensed by GM and GM is the one that determines warranty repairs. Nothing against Amsoil but you need to know what you're getting into before you roll the dice...kind of like getting your engine "tuned" which we all know GM says "tough luck" if something happens to any part of your powertrain. Caveat Emptor!




.....assume the car was neglected across the board.I just worked on a car in which the owner was using low octane fuel the whole time. If a guy is that much of a cheapskate to want to save 3 bucks at a fill-up, he definitely dint keep up with fluids.
But if you go that route, what about the filter and any potential particles still at the bottom of the pan?





Thousands upon thousands of the cars will never have the A6 fluid changed prior to the factory service suggestions, without failures. By far, many of those may go twice the miles or even never and still survive, if they are not driven abusively.
I personally fully (12.75 qt) changed mine at 71K, due to putting in a high stall converter to improve my times at the drags. I doubt the A6 gets more abuse than racing and also that any particular brand of proper fluid will cause the transmission to fail.
If fear of the unknown is the reason to change the fluid, then you should never buy a used car. If you do change it, do it 3 or more times in the next 1000 miles to get a much higher percentage of that nasty old fluid removed. Consider draining/flushing/changing the power steering, windshield washer, coolant, differential, and brake fluids too.
