(function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } Does what its supposed to. A guy i was working with was telling me about this but didn't know the name. I just searched on Bolo and could tell this was it by the way he described it. You can't expect it to be perfect but it sure is close to it if you want to get rid of than transmission slip bucking from your car.

5.0 out of 5 stars Value pack of the Best 1st step on a dying transmission

Super value!If you have a couple older cars in your ”family fleet” this can be a life saverAdd to vehicle transmission when experiencing torque shudder ( example honda v6 with vcm, mazda cx9 and arly failure etc)If this doesn’t help… call your transmission shop and set aside $3k…Slightly different package graphics but this is from the official company store so I don’t expect to be a fake.

5.0 out of 5 stars Took a little time to start working, but I'm so happy it finally did

2008 Expedition, 300k miles. I've had 3 tq convertors put in this truck, not sure what the problem is but they just won't stay together. First 3 were on the company dime, now I'm out of warranty and the shudder at low pressure cruising has returned once again. In my case, the trans works great, but cruising at 30-40mph, with very little gas pedal, it'll slip and shudder and the only way to get it to stop is to hit the gas and add a little more pressure to the system. This will get worse very fast if you just let it continue to shudder, so I'd quit using the cruise all together, and just stay vigilant on the pedal to avoid the problem on slight inclines at highway speed. I'm not quite ready to send her to the scrap heap, so I figured I'd give this stuff a try. I put one in thru the hose on the cooler in front of the radiator. No dipstick on this trans, so difficult to get to. After 2 weeks, no change, so after reading a few more reviews I added two more packs. With 3 in there and waiting another few weeks, it's really made a huge difference. I can leave the truck on cruise control at 60 again without fear of the shudder. Not sure how it works, but I think mine is probably one of the more severe cases, so if it can fix mine it'll likely help you too. Don't expect results over night, mine took over a month to "soak in?" but now it's working like a champ. Hopefully I'll never need it again, but I've got 3 left out of the 6 pack if I do.

5.0 out of 5 stars Great product for the judder in a Honda

j. · April 2, 2024

I have used this product in any Honda vehicles. Once you get up there in miles the transmissions sometimes can get a little judder about 35-40mph. Time to change the fluid(3 times) and add this. This seems like some snake oil but in does work incredibly well. I know several mechanics and repair shops that swear buy it. I was extremely hesitant the first time I used it. I did not believe a tiny amount of magic fluid could correct the issue. I tested it on in a Honda CRV that had a bad judder in the trans. I added this stuff WITHOUT changing the fluid first and the judder/vibration went away. I drove it like that for a couple months and then decided to change the fluid. I did add this to the new fluid. Now 5 vehicles later it is still my go to solution.

Fixed my issue

5.0 out of 5 stars Really does work

I was quoted $1200 to replace my torque converter in my 2013 Ford Edge. I saw this and thought what the hell. I put 2 in my transmission and in about 40-60 miles the shudder was gone.

yeah happy with everything

Stopped a Shudder

D. · July 30, 2024

Our 2007 Toyota FJ Cruiser started to shudder, so we took it to a transmission specialist in our town. They changed the ATF and added this product. The shudder stopped. Now, 100,000 miles later, driving 16 months in Mexico, all over Canada & USA and up to Alaska, still no shudder. We change the ATF more often than needed, because we are full time towing a small travel trailer. We also change our own ATF because after having 2 places doing it incorrectly (One being Toyota, under-filling) and another over filling, we do it ourselves. This vehicle doesn’t have a dipstick, so it seems to confuse people on the correct process. We add this product with every ATF change. This high mileage truck drives and shifts beautifully

IT WORKS!!!

I did my research and everything I found says this stuff works. I used it in my 2007 Escape with 250,000km on it. I am amazed at how well it actually worked. It's like it took the last few years off my transmission. Glad I bought the 6 pack. I also put 2 tubes in my 2005 Focus with 345,000km on it.
