I have a 2014 M7 Z51 with about 30,000 miles and I want to change out the tranny fluid. Is Redline D4 ATF a good choice or should I stick with what GM recommends? Thanks.
What makes Redline vastly superior to the factory lubrication?
Bill
I have no idea if it’s superior in any way but I do know my Z06 shift much smoother with it, my Land Rover Defender 110 shifts much smoother and with it, and my Toyota Land Cruiser (Auto trans) shifts much smoother with it.
I've swapped for Redline D4 ATF based on recommendations here. However, I'll be in the minority group that based on subjective feel OEM GM is better. On my next change I'll be going back to OEM GM fill.
I too just changed to Redline D4 ATF, haven't had a chance to drive it yet.
I ran the car on my lift, the shifts were way better.
Now lets see how it is on the street.

I too agree GM OEM fill gives me the best shifting feel. Been through this circus on the f-body, C5, C6 and C7.
I think 7.4 pints is the spec. You'll have a little left over from a gallon jug. Be sure to have the car nice and level then pump it in until it just begins to trickle out from the fill opening.

What I changed mine to as well.
