As many of you know, I own a 2008 Pontiac G8 GT which is equipped with the 6L80E auto trans. GM recommends changing the fluid every 50k for extreme conditions and 100k for normal operation.

Right now my G8 has 53k on it so I'm considering having a simple drain/refill with a filter change. I have a tune on the car so the shifts are firmer than stock and I have taken the car down the 1/4 mile roughly 15 times. My commute to work is mainly highway so the car doesn't sit in traffic too much.

Let me know your thoughts as there are varying opinions on this.
