Transmission Fix

We use this additive at the auto shop. Shockingly effective. The additive has dramaticallyimproved or eliminated most transmission shifting problems and brought some failingunits back to drivability for months or more.

My transmission has been slipping between second and third (and viceversa) for a few months now, taking a little too long to upshift from fourth to fifth and fifth to sixth, and sometimes slamming hard into second from first. I have already tried other products like Lubgard shudder fixx, Lubegard Red and Rislone. Each time I have drained my transmission (NOT FLUSHED), refill with the appropriate 5 qt, and one of the mentioned additives. They all worked immediately, but, in each case, it didn’t last, after two days to a week, the problems were right back in my 2015 Chevy Traverse, infamous for these symptoms.Well, they say the third time is the charm, but in my particular case, it was the fourth.After doing another drain (the fourth and last one as of this writing), and using this Bar’s Leak Trans Fix product and not really expecting anything, well, nothing happened…at first.That was almost three weeks ago, and I have to say, I am impressed now; my truck’s transmission seems to be getting better by the day to the point where almost all the symptoms are gone. The transmission shifts better than it ever has since I started having problems with it. I don’t know if it will get better, and I don’t know how long is going to last, but the slamming and slipping are gone (and it seems to be getting better), all I know is that the three previously mentioned products didn’t work in the long term for me.Bar’s Leak bottle does say that product may start working after 150 miles, and in my case, it did.Waaay better than the $5,700.00 that I was quoted for a rebuilt transmission and labor, insane.Extremely happy with product as of now, and I wouldn’t hesitate to do a second treatment if required, which is recommended as per instructions on the back of the bottle.Was it the four drains and refills that helped because now my transmission is full of new, clean fluid?, is it a combination of Bar’s Leak Trans Fix and whatever residue is left of the previous three products that I used?, I don’t know, but is working.

Love this stuff. There is quite a bit of liquid so to avoid overflow i pumped out a bit with a small hand held transfer pump. Worked like a charm level was perfect. Started working the same day. Extended the life of my failing transmission for sure.

Used in 2010 GMC Yukon, made a big difference!

I was lazy and used an electric pump to remove the fluid through the dip stick and filled back up with 1 1/2 bottle of transfix and the rest with Valvoline high milage transmission fluid. The slip went away, and I was able to sell it after driving around for a few days as recommended per directions.03 Expedition 207k

Ill have to say im glad i used this stuff it actually made a diffrence in shifting easier. First and reverse was always a random problem getting it in gear but now it goes in all gears easier but still has a random issue that first does not want to go just not as often.
