Lubegard19610 Instant Shudder Fixx, 2 oz.

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.

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.

My /013 v6 dodge avenger was shuddering badly due to the torque converter going out according to the mechanic. I put a bottle of this in the transmission, drove it 5 miles and didn’t have a problem. So far it’s saved me $6000 for a new transmission rebuild. I will update this review if I have any problems.

Absolutely stopped the shudder in my 2013 v6 camaro....2000 miles and still no shudder...hope it continues to work

I don't pretend to understand whether this stuff make the ATF more slickery or more stickery. I don't care it the next thought. What I do know is that after two rebuilds and no one being able to take care of the shudder I felt.... Like I was going to get sidelined on a roadside, again. So much AGAIN that I have the tow company on speed dial. So ... Along comes t<his little tube of 12$ goo and it solves my issue. 12$. I still feel just a very faint hair of shudder, I think. I could be just uber paranoid by now. Bottom line- it has worked on my 2004 GMC Denali 146k miles. I didn't know if it would but. . . Itdoes.

Had a little shudder on downshift. Immediate smooth shifting. 2012 Ford Edge

I have a 2007 Honda Pilot with 235k miles and it has been meticulously taken care of. The transmission started to shudder when going into 3rd gear. I have used Lubegard Transmission additive in my transmissions for years and when this shudder started to happen I was surprised. I took it to my transmission guy who I have recommended to my customers to for years and he recommended I try this. Well after about 300 miles of putting it in the shudder has gotten worse. I still drive the car on short trips but its a real nuisance. I guess the transmission has just gone and because of the age and mileage it isnt worth installing a reman or new transmission.
