Last week I did a 5 qt. cooler line pump out, pan drop and filter change on a LS1/4l60e with great results. After a week of letting the pcm adjust to the new fluid, the car shifts better than it has in years. Even better than new Dex III changes were.
Shifts are firm when pushed as they should be on this F-body, but smoother and more consistant than before. Easy going driving is very smooth. We will see how higher temps of summer will compare. I would expext the fluid should be better in all ways if the specs. don't lie.
I just wanted to let people know who are nervous about using the new stuff. Castrol Dexron VI was used from AA for $4/qt. minus -$20 off $50 online discount. (approx. $2.50 per quart)
