Re: Red Line in your MN6? (jojog)
I switched to Redline fluids in the diff and MN6 (D4AFT) at 30K miles. I had no problems whatsoever with the stock fluids. Shifting was average.
After Redline, shifting seemed smoother right away.
But after 1 year/10K miles, shifting started to get a little rough. Then I developed a fluid leak. It turned out to be the rear seal of the trans. It's a $3 part, but $600 in labor to change it out (covered under GMPP, luckily for me).
Of course, I can't say the Redline caused the leak, nor can I say it caused the increased shifting effort. On repair, dealer refilled with stock fluid and I'm keeping it that way!
Also, I belive it's incorrect to say D4ATF is Dexron approved. I think Redline says it meets the specs, but it has never been certified by GM.
Just one man's experience.

DTE requires me to use it in the diff they built into 4.10's for me if I want to keep their warranty in effect.
I use Amsoil in the block and tranny.

Amsoil,Redline, and Royal Purple all use superior base materials that Mobil 1. Mobil is just a huge company that can make GM a deal they can’t refuse.
There are tons of test results showing Mobil 1 coming in last in all categories compared to these.
You can’t fight the warranty folks but once it’s up I thing your crazy to stick with Mobil 1

Been using Redline in the tranny and diff. for 2 years now with no problems. I will keep using Redline since I haven't had a problem and it definately made shifting smoother.
