Search "Redline" (search tab at top of page) and you'll get plenty of opinions without having to ask for more.
In short, excellent stuff but apparently, manufacturer recommends you have aprox 3000 miles on your motor first.
I put Red Line "Shock" in my tranya couple of weeks ago.
Seems to be less clank when shifting gears now. 1500 mile roundtripper next week - we'll see then. Specks
I had Shockproof in my tranny for 5500 miles and when I drained it out it looked nice & pink like new. (Pepto Bismol in, Pepto Bismol out. ) The magnet on the drainplug was spotless- not a single speck of metal. I would've left the Shockproof in there for another 10k-15k miles but I wanted to try Spectro's Platinum 6-speed gear oil as it was advertised to specifically target the 5th gear whine in the new 6-speeds. I should've saved my money because it's no quieter than the Shockproof it replaced. The Spectro is good oil so I'll leave it in for a year, but it'll get drained out next spring & Shockproof will go back in.
Redline definitely makes good oils...
