Lubegard 19610 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.

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.

Worked as advertised.

Had an auto service add this to my 2010 Ford Expedition transmission with 151,500 miles because it felt like the torque converter was disengaging between 29 mph and 45 mph. I also heard some type of roaring that sounded like wheel bearings going bad. I was quoted $425 for a transmission service and about $4200 for rebuild. The dipstick for this 6 spd transmission had to literally be checked under the vehicle. So I found a shop to put it on a lift. Do not attempt to check fluid level unless it is running. The mechanic thought it was related to the engine and told me I was wasting my money. I told him to do it anyway. On the way home I found the smoothest blacktop roads to listen and feel for any noise or shifting issues. I could not duplicate the previous problems. THIS STUFF WORKED FOR ME! I’ll try to update this review once I put a couple thousand miles on it.
