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.

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.

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.

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.

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

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

The listing shows quantity of 3 many times but they only sent 1 tube.Would have given it 5 stars because it worked perfectly in my 99 Grand Marquis that had developed a convertor shudder. Added it and the shudder was gone.

We had an f150 come in with this shudder problem. This product actually fixed it right .
