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!

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.
