Its not that its a v6, it's the gear ratio. I was reading about rears and lube and cooling. I was surprised to find out that the 3.73 gears will run much hotter than the 3.08 that the car came with. I change fluids more often than most people. The trans needs a full flush at 40k, and the rear too. They will be changed about every 40-50K after that. So I'll be putting in a drain plug in the trans pan to make that chore easier, and I thought it would make draining the rear easier, quicker and less messy. Plus I don't have to worry about gasket leaks on the rear. With a magnetic drain plug, I will see if there is unacceptable wear occurring.

I often keep my cars to over 200K miles. Changing the trans and rear fluids makes high mileage possible without trans/rear failure.
