Worked Fantastic on HONDA Pilot 2016
I had problem of slipping and downshift thuds in transmission, ALL this stopped once I replaced the Fluid and added this fluid. it took only few miles, but should see underneath if it fixed the leaks, after I run for 200+ in single run Worth the Money and trouble

5 Star Product
The Dynaflow transmission in my 1953 Buick has been sub par for a while, including a leak. The first time I used Barr's transmission treatment the improvement was staggering. No slippage and close to perfect shifting. A little early to tell if leakage has been reduced but I will report later. I have another bottle ready to re-treat as needed and will reorder to have some on hand. At this stage I am no longer considering having the transmission rebuilt, saving a few thousand dollars!

It seems to actually work.
I honestly can't believe how good this stuff works. It stopped a pretty bad leak. Or slowed it to a minimum that I haven't noticed. I'm shifting gears more smoothly too. Its been over a week so far since treatment. So far, so good. Hell yeah!

I don't normally buy non-Prime, but I'm glad I did this time!
Wow! I was doubtful when I ordered that this could fix my transmission. I have a clear leak and it causes a heavy gear shift. Within a day of adding to my running vehicle with a funnel through the tranny dipstick slot, the heavy shifts were gone. I have no evidence the leak is still there nor corrected yet, but felt a difference despite me expecting nothing.

There are companies out there that say the truth, your company is one of them.
Your product stopped the transmission leak immediately. I do recommend this product with no reservation, it WORKS!!!!!!
