CVT Transmission Fix


  11 Reviews

The most advanced Continuously Variable Transmission (CVT) fix you can buy. Engineered to stop slips, sluggishness, and hesitation – all while safely and quickly sealing any CVT leaks. After over a year in development, we’re proud to introduce the finest CVT repair formula on the market, bar none.


Shake container. Add entire bottle of CVT Transmission Fix to transmission. Do not overfill. Depending on the CVT problem, results will either be immediate or noticeable within 200 miles or 4 days of driving. In CVT with seriously damaged components, a second treatment may be required. In this case, it is suggested that the fluid and filter be changed, and a second application of CVT Transmission Fix be added.

Continuously Variable Transmissions (CVTs) are great – until they are not. CVTs are more complex and specialized than a standard automatic transmission, and repair costs often are very expensive. And when a CVT cannot be repaired, it needs to be replaced, which can be so expensive that owners are forced to sideline an otherwise perfectly good car.

The good news is that we have a solution that can help you keep that car on the road and give your CVT a new lease on life. Introducing Bar’s Leaks CVT Transmission Fix – a product that spent over a year in development in our lab to specifically address CVT transmissions issues such as leaks, stalling, slipping and hesitation. This is not a regular transmission formula that’s been modified for CVTs – this is formula specifically engineered for CVTs and the problems they encounter.

Before scrapping your car or footing the bill for a replacement CVT – or even a complex CVT repair – try Bar’s Leaks CVT Transmission Fix. It’s designed to fix your CVT problems at a fraction of the cost, and it works within minutes. No mechanical or technical expertise required – installation is simple and straightforward.

Like a new transmission

I have recently used your CVT Transmission Fix and it has seemed to work great. The tranny has about 200,000 miles on it and was a little noisy. This product has made the transmission smoother and quieter.

Never disappointed

Thank you!

So, you saved me over $5k on CVT repair! Four years ago, at about 20k miles, my 2013 Nissan Pathfinder tranny began to slip so badly that I could not pull out into traffic. I found your product Bar's Leaks CVT Fix 1414 and followed label directions. Within a hundred miles of driving, the slip totally disappeared and stayed strong! The car now has 67k miles - and is starting to slip and vibrate. Right now, I'm having my local Nissan dealer flush the CVT and replenish the filters and NS-3 fluid; and another bottle of your CVT 1414 Fix. We are headed up to Michigan for vacation and we love our Pathfinder and YOUR PRODUCT.

Bar's CVT transmission fix

I have a 2007 with 82,000 miles, and it started to shudder, jerk, and finally slip really bad! I barely made it home and thought my transmission was history. Well I went to AutoZone in Halawa on Oahu, and usually use the Lucas transmission fix cause it works really well too, but they didn't have any in stock, and right next on the same shelf I seen this (Bar's CVT transmission fix) so I grabbed a couple and went home and siphoned out what ever I could with a cheap manual siphon pump from City Mill hardware store in Waimalu on Oahu Hawaii. And Next I added two bottles of Bar's CVT Transmission fix into the fill tube and topped it off with fresh CVT transmission fluid and took a drive and so far it is working smoother than ever before, and there is no jerking, or shudder, and most of all it doesn't slip any more!!! I will definitely keep an extra bottle of it in the van and will do another flush flush and fill again just to keep it clean, I highly recommend it to anyone, before taking your car to the mechanic shop !

Bars leak CVT Additive

Use this works! I drive our '14 Sentra too hard and fast in heat out west. The first CVT went out at 60,00 miles. At 120,000 it was shot again and I didn't have the $4,500 to replace it. Dealer told me that if I only drained out the tranny oil that would drain out when the plug was removed that I needed 4 qts to refill it to the right amount. So I had my oil change guy do it when I changed motor oil and then I put in a bottle of the CVT additive. The tranny is perfect now. I drive the shit out of it again. During the time I was changing the fluid I held it under 60 all the time. I don't see why this wouldn't work on any CVT. NOTE: My Sentra has no dipstick so I can't check the oil level. Go figure!

Quick Effective CVT Cure..

We have a 2013 Nissan we purchased for a child and noticed some issues with the CVT tranny that could have cost a fortune to fix but we decided to try this CVT Transmission Fix first.

The results have been amazing to say the least. The shaking as well as some of the noise and roughness from shifting have been greatly improved and car feels somewhat 'new' again. Definitely a great investment to provide piece of mind for our child going off to school. Would buy again!

Thank You

Have 2013 Altima with 135000 miles. Just purchased from a senior citizen. Almost new car even still smells new. Garage kept. Highway miles only. All service records but trans only serviced once. Started slipping a bit along with vibration. Changed oil and added your product. In only 25 miles about 75% restored. Added 2nd, in 75 miles now 90% improvement WOW!

Bars CVT fix

I bought a 2013 Mitsubishi Lancer GT with the CVT trans, It was at a auction and I thought it was a manual trans, I had to haul it, changed the fluid, didn’t help a thing, I saw the Bar's Leaks at Autozone thought I’d try it. What’s $30.00 for 2 bottles? I drained out about the same amount that I was going to put in, Poured it in and drove it about 3 or 4 miles turned around and before I got back it was working as it should. So it worked for me. I just hope it works 1 more time because I bought a 2012 Nissan Quest and the trans is doing the same thing, I’ll let you all know if it works again!

Cvt fix

I give it a 3 right now because I just added it in yesterday and only drove a little and parked it all night. I drove today and it definitely drives better and doesn't drag or whistle or skip. I will know tomorrow when I drive on the highway to work. Glad I looked this up and bought it I will keep some on deck for the future.
