Bar's Leaks Transmission Fix, Automotive Additive, Vehicle Type: Universal, 11.5 oz

Out of a few tried in a slim market over the years, definitely favor this one, seems to be the best, slightly thicker or heavier weight would be nice, but none are, this ones the thickest, no lucas. Great product.

I was having trouble with my transmission slipping and the shifting was very hard also had a small leak once I put the Trans Fix in my tranny and drove approximately100 miles everything seem to smooth out and the leak stopped. I am very happy this product and I will definitely use it again. Thanks Bar's Leaks

I honestly wasn't sure if this was gonna fix my trans problem cuz it was getting pretty bad but after changing my trans filter and fluid and adding a bottle of this my truck started driving like a new one it completely got rid of my shifting problem thanks for such a great product

[This review was collected as part of a promotion.] I put this in my 1996 corolla to help an issue which I thought was slippage. While it did improve the "slippage" a little bit for a while I found out that the real issue was the car needed a new torque converter. The car did leak transmission fluid and with this product the leak slowed down to a manageable level. A couple replacement parts later there is no leak at all now! Give it a try!

[This review was collected as part of a promotion.] Put this in my forever truck—an '04 Tahoe with 220K miles and the original transmission—after noticing occasional 1–2 slips and light thumps. So far, it's smoothed out the shifts. Appreciate the clear directions and looking forward to trying more Bar's Leaks products!

[This review was collected as part of a promotion.] I'm a repeat buyer. First time I purchased this product it was for my ‘15 Nissan Altima with the CVT trans and at that time I was just doing any and everything to get it back going which it did the trick to my surprise. Now I'm back with another Nissan Altima(different car)and again it got me right back on the road. Great product!

[This review was collected as part of a promotion.] I was in my work truck with 213,000 miles and the transmission started to slip to the point I was ready to call a tow truck. I saw a auto parts store and thought I would give it a shot and try the TransFix. I added it to the transmission fluid as directed and started it up as soon as I put it in gear I could tell it was back to normal that was over 300 miles ago and it's still shifting great with no issues. I'm not sure how it worked but I can assure you that all of the problems were fixed on minutes.

vwet good product at an affordable price to help you maintain your transmiszion oil working good and no oil leaks as I will recommend it

[This review was collected as part of a promotion.] My transmission had a small leak. I would usually keep it topped off, but there were a few weeks where I got behind and ran it too low and my transmission are acting up. I used this product and it brought my transmission back to almost new. I'm still driving the truck (2004 Chevy Silverado 1500 with a 4l60 trans) daily and haven't had an issue since

For my transmission, this product did not help all that much.But I did notice some improvement. I don't think that's the product.Maybe just my transmission.
