I'm got an '07 TL with 60k miles on it and am trying to avoid the 'ol glass transmission curse - I've had 2 Hondas and an Acura before this

Anyway, after much reading up on Acurazine I opted for the 3x3 drain & fill using Redline D4. I noticed an immediate difference the first time around. Faster and quicker shifts. But after doing it the 2nd time I feel like I'm back on the dealer fluid. Shifting is slower and feels less precise.

Is there a way for me to test and see if the D4 is actually in there? I'm paranoid my mechanic put in the cheaper stuff and kept the D4 for himself...

 

Send a sample to Blackstone?

 

why dont you do the work yourself?? its even easier then changing engine oil . Id prefer that over the other any day...

 

That's why I always stay there and look when someone else works on my car.

 

If the redline ATF is as expensive as their oil I would never give it to a mechanic to put in. There's just too much of a risk they would keep the fluid and put their crap.

 

land of the rich, when I did redline awhile ago the first 1x3 I noticed a huge difference in shifting as well but as I changed the other 2x3 I didn't notice a difference anymore and I did it myself. Alot of people say they notice more of a difference during the second drain but for me I didn't feel any bit different after the first drain. Then again I let it drain for a long time as I walked away for awhile while it was draining. Next time do it yourself, it's really easy. Look for the blue bolt to the right (drivers side) it doesn't even take a socket, just a socket wrench with no socket.
