Lubegard 19610 Instant Shudder Fixx, 2 oz.

We are still impressed by this stuff, as it stopped the shuttering in our Buick Enclave. (2019). It also helped out the torque converter as it's much smoother now and not as "clunky" at 20-25 mph. The local Buick dealer said the transmission needed replacement for a cost of 6k. They said there were metal shavings in the fluid, another Lie. We changed the fluid, and a week later added Lubegard. The Buick runs and shifts smoothly now.

I've never written a review on an Amazon purchase before, but this product impressed me so much I had to. I've lived with a shudder in my CRV for years and always thought I'd eventually be faced with replacing the torque converter. I did confirm with a mechanic this was the issue after having a fluid and filter change done. This stuff worked. Poured it in and the shudder is gone. I have no idea how long it will last, but its working so far. Amazing product!

Transmission was shuttering like crazy taking off put this in a shifts and drive great

It seems to work well used it in my 1999 Town & Country stop it the shutter don’t know for how long it will last for the price might as well try it before replacing transmission

2007 BMW e90 328i 50k miles GM 6-speed Automatic Shudder went away after flush and fill of new trans fluids and adding this product. The fluid that came out was worn but the shop said they have seen much worse. Shifts like it should with so few miles. Given the fluid that came out, I don’t think simple fluid replacement would have resolved the shudder alone. I’m happy with this purchase.

My 2007 Toyota FJ Cruiser developed significant "shudder" in the torque converter of the transmission at around 130,000 miles. I took it to the dealer and they confirmed the problem and said the only fix was to replace the transmission and they wanted around $6000 USD for new transmission replacement. I talked to a mechanic that did work for my parents and he suggested adding this along with servicing the transmission (replace fluid, screen, and new gasket for cover). It worked. After driving about 30 miles the shudder in the transmission disappeared.

I had developed a shudder/vibration in my truck when I was just cruising on the highway at low rpms. I couldn't figure out what it was. I checked everything on the driveline, rotated the tires, lifted the truck and put new tires on it, and it never changed. I was about to give up and take it to the dealership for them to keep my truck for a month and waste my time and tell me they couldn't figure it out, but I saw a video of a guy with the same problem I was having and he suggested using this. It worked right away. I expected to have to put some miles on the truck before I saw any results, if I saw any, but it worked right away. When I went to work the next day the shudder/vibration was gone and it even seems to shift smoother and downshifts better when it needs to without hesitating or waiting longer than it should like it was doing before. I plan on doing a filter and fluid change and I'll be adding a tube of this to the new fluid when I do.

Worked great and stopped shudder for 5000 or 6000 miles

Had quite a bad shudder on a Ford Smax 2019. One tube did the fix. I still can’t believed it worked. Amazing!!!

Tremblement sur Mondeo 190cv bva8 (8f35). J’ai mis le produit dans l’huile de boîte et directement problème réglé. Incroyablement efficace.

Works like a miracle if you can get a mechanic to put it in Lasts about 2 years.

Ne. Traite que 2l pas utilisé ai trouvé mieux a renvoyer

Usato sul cambio automatico di una land rover ha tolto le vibrazioni in modo quasi miracoloso.... ho effettuato due cicli a distanza di 2000km per rendere ancora più fluido il cambio Quando lo maneggiate dotatevi di opportune precauzioni per proteggere occhi e mani!!!!!!!!!!
