Good afternoon Scotty, I have a 2010 Acura RDX with 70k miles. The transmission fluid looks red, but when I shift between Drive & Reverse, it has a 2 second delay. I want to help it work better. Will AMSOIL signature ATF be good for my vehicle, or will Acura ATF be better?
the delay is intentional so you don't accidentally blow up the drivetrain
I appreciate your feedback! 
Still wondering if AMSOIL ATF is better than Acura ATF.
I haven't seen any studies or experiments comparing the two. My guess is that you would notice absolutely no difference between the two in daily driving.
Most likely a a reverse shift solenoid valve is acting up. Could be because a solenoid harness connector is loose. Could be a valve is developing a fault - it operates on resistance, … range of 12-25 Ohm. If it goes out of range it causes problems. It could be just a dirt/gum that retards it’s operation.
Have the ATF ever been changed? If not, … I would do drain and refill procedure - inexpensive try. See if it helps. It just may. Also, after drain and refill, see if any other shifts change noticeably. If you notice a difference, it’s probably a dirt accumulating. Another one or two drains and fills would probably be in order if the first one helped.
Anyway, … that’s precisely why we here always advise that regular and timely ATF drains and fills are important, … especially to those who buy a new cars for a long, long ride.
F.S.
As to AMSOIL, … I’m not sure if it will help. I would stick with a Honda ATF.
Nice.
