T6A Automatic Transmission Fluid Treatment. For transmissions with an Oil Capacity up to 6 quarts. Safe for All Manual & Automatic transmissions.

I was pleased with the perceived improvements the engine treatment gave my 2014 gmc Sierra 6-spd (early production model, later they swapped to the 8-spd with 6.2) so I tried the transmission version. After about 600 miles I have noticed an empirical consistent improvement in shifting particularly between 2nd and 3rd which had an audible ‘clunk’ and jerk going either way before use.I am a buy new then over maintain to get the most bang for my vehicle bucks kind of guy. Going to add this the diff and transfer cases on the Sierra next and go wide on all vehicles if I feel the same way in a couple thousand more miles

I gave this product a try.It worked great and I used some remaining fluid for another car made a big impact on the shift quality.

Have a 2014 F250, 6.2L gas with 196,000 miles on it that began suffering from the typical transmission pump whine that signals the end of transmission life. I was hoping to push off a rebuild and so I figured I had nothing to lose by trying the treatment, after I saw some guy on YouTube who swore by it. At any rate, it work. Transmission is now quiet and shifts great.

2003 Honda Accord (261k miles).Transmission serviced every 15k (approx.) since I've owned it (starting at 143k). Began slipping since the last interval. Not bad but enough to know that it was probably at the end of its life. Decided to start saving up for a new transmission but saw this and thought I could prolong the life of the transmission until I saved up for another.Dropped the additive in and drove for 15 miles. Transmission completely failed. It will not shift into any gear now and the car will not move.Cautionary tale for those on the fence about this additive.

I did some extensive research on transmission treatments to prolong the life of my transmission in my daily driven Camry and decided to try this product. So far very happy with the treatment and have noticed smoother shifting.

Product did not help at all. As a matter of fact now it sounds worse when the vehicle is cold and for the first 10 minutes there is a weird noise as if it is scrubbing and then it goes away my car was not doing that until I added it. Thinking about replacing the transmission entirely. Very disappointed.

I drove 500km on this road,no changes and improvements, deception
