Default Mn6 fluid

I just changed the fluid in my tranny and the fluid that came out was brown is that what the stock fluid looks like mine is a 2003 mn6 and it only has 25 km on it

It is red new. Trans fluid gets hot and turns dark, just like any other lubricant.

Your new red fluid will be brown eventually, if you don't change it sooner.

I change MN6 fluid about every 50,000 miles (103,000 miles on 1998). This is when it gets hard to shift or grinds going into sixth. I understand that MN6 transmissions are sensitive to dirty fluid. I don't know why GM says you never have to change it?

I have used Mobil 1 and Amsoil ATD, both synthetic, they improve shifting. I was surprised it didn't last longer.

I never heard of Dexron 5 ! It calls for Denron III, and there is Dexron IV.
