Well as one Fella said in His review, I have been working on cars for over 40 years and don't get stumped very often but this problem was weird but very common to CVT Transmissions on Nissans. 2 Tubes and 7 minutes later, the Judder, Shudder was gone, and I mean gone. I had to stop and try to force it to make another noise, but it didn't. I just drove 60 miles totally quiet on 230,000-mile car. Its almost unbelievable to Me. I had a wild guess that maybe it the Torque Converter, but the noise was gone once You were moving. Ima a happy Fella now. Thanks, folks, for a wonderful product, S Thompson Oregon.

This stuff is awesome, I’ve been in the automotive industry for 32yrs, I always fix my own vehicles and rarely ever fall for the fix in a bottle gimmicks.My wife’s 2013 Infiniti QX56 has had a weird shutter/surge issue for 2yrs, it would only do it between 1200-2000RPM’s under a light load. It has been driving me crazy, I don’t like when I can’t fix something and I couldn’t figure it out. Finally read about this stuff, put 2-2oz tubes of it in and within a mile it was gone.I was absolutely blown away and still amazed that it fixed it. She put 1500miles on it last week on a road trip and it did great. I was ready to sell it or trade it in assuming the trans was going out and 4oz of this stuff saved us from a car payment!!

5.0 out of 5 stars This stuff really does work.

I was very skeptical. But someone told me about it and I thought well it’s worth $15 before I change the torque converter. Added this stuff and never did it again. And it shuttered every day. Now it’s been over 4000 miles still working it saved me about $700 . I was about to have the torque converter changed. I strongly recommend this before I would change the torque converter.

4.0 out of 5 stars Seems Like A Go...

I've had a 2009 Ford Flex since new and it's no secret that the '09 was sort of riddled with teething problems... One of which was the transmission in the earliest models.I've been lucky with it so far, that is until we were returning to Ohio from Florida last month.We stopped at a motel for the night, and while idling through the parking lot trying to find our room, the vehicle seemed to lose all of it's power as I tried using the accelerator to maneuver into our parking spot.The only Auto Parts store in the area DIDN'T have this product, so I bought and added another brand and that got us home, although the torque converter would still shudder on moderate acceleration, say like while entering the freeway.Fast forward to this week... I changed two thirds of the transmission fluid and added two tubes of this product while refilling.On my first ten mile drive to the next town to do some grocery shopping, I immediately noticed a marked improvement over what I was getting before.I drove the Flex "the long way home" on the return trip, which came out to around another 20 miles and the shudder upon acceleration was even less apparent.Hopefully with a few more miles of driving, it will dissipate even more.All in all, this product has seemed to really revitalize the transmission in my vehicle... So I'd say that it was well worth the money I spent on it.I'd recommend this product to anyone who's experiencing torque converter shudder in their personal vehicle... Provided that their transmission and this product are compatible. It's not recommended for CVTs and similar.

5.0 out of 5 stars Fixed the TCC shudder in about 200 miles.

The torque converter in my truck developed a shudder immediately after I changed the fluid and filter at 200,000 miles. After about 5000 miles it was still present so I tried some of this shudder fix and it worked. Took about 200 miles for it to totally work in. Doesn't seem to have affected any other operation of the transmission.

5.0 out of 5 stars A REAL, HONEST review from a self-proclaimed shadetree mechanic..

J.W. · January 11, 2023

This is a real, honest review by someone who's actually bought and tried this product. I'm not compensated for my findings, I have no affiliation with the company, LubeGuard or it's product other than being a consumer and purchasing it for my own personal vehicle. I am a self-proclaimed shadetree mechanic. I do most of my own car maintenance and repairs in my driveway. I'm experienced with everything from basic oil changes, tune up's, even timing chains, lifters, fuel pumps, etc. I've always been too broke (cheap?) to hire professional mechanics for most things.My daily driver car, a 2007 Ford Five Hundred/Mercury Montego has about 147,000 on the clock. I really love the car, it's still a nice ride for it's age and milage. Naturally my heart sank when I experienced a "shudder/studder/hesitation". I once thought it was ignition related, so I began pulling spark plugs and coil packs in hopes of finding the culprit. I cleaned the throttle body, I cleaned the MAF sensor, I dosed the fuel with a heavy dose of Techron and Seafoamed the intake manifold. Nothing helped. Nothing really stopped it.. Until now.What I thought was ignition/fuel related turned out to be transmission related. Specificially, the torque convertor. I was experiencing TC shudder - and knowing how expensive transmission shops are, my heart sank a little. Ultimately TC shudder is a mechanical problem and the only real "fix" is to replace the faulty part. I could feel my wallet getting lighter already. Then, I stumbled across this product. For less than the price of a large pizza, I bought the "two tube" pack with the thoughts of dosing it hot and sending it. What happened next defies my logic as a shadetree mechanic. Never in my life have I ever experienced a "fix in a bottle". This stuff though.. Ha, let me tell you. Blew my mind.It worked, atleast, on my drive to work this morning it did. Theres a certain spot in town that my car always, ALWAYS shuddered. Always. The speed, the load on the engine, everything in this location was always just right to initiate the hesitation. This morning though.. I felt nothing. Just a smooth cruise right on into the office.Now I'll go on record and state this is NOT the only thing I did. I also simply drained the transmission (did NOT flush, simply drained what was in the pan), refilled with fresh clean fluid, and two tubes of this stuff. I don't imagine the transmission fluid alone helped it. I suspect the magical red unicorn blood in the tubes played a part, and I'm cool with that.If you're experiencing transmission shudder.. Do yourself a favor and try this stuff. If it works, you've just bought yourself some time with a bandaid that actually works. If it doesn't, atleast you know you tried something that has an actual track record of providing results.UPDATE: Approximately 700 miles in and still smooth as silk. Mind is still blown.UPDATE: Approximately 1500 miles in, still perfect. Zero sign of shudder.UPDATE: Today is 9/19/23 and I'm sitting at 152,000 on the odometer. Approximately 5,000 miles since the Shudder Fix. The car is still driving and shifting just fine, every bit as good as that first drive with it.

Works like magic

I own a honda civic 2012 model and it was shuddering exactly on its 3rd gear low rpm that its seems the engine will explode. Luckily I came across this product, I ordered and received it about a week here in uae. I put two 2 tubes and drove the car, i really can’t believe it. It works like magic, the shuddering was gone and my car feels like brand new again. Hope this review helps. Dunno when it will last, but hope it’ll last a year or two.

Single best thing I’ve ever bought

2003 Range Rover hanging on to gears revving high. Banging into 2nd and 3rd. Shuddering like mad vibrating the whole car. You would say it’s time for a gearbox rebuild. Changed the oil and filter pan to no avail. Nothing to loose by dumping 2 tubes of this stuff in. WOW !Instantly the shudder is gone. Can’t feel the gear changes any more and changes up about 1800 rpm instead of 3500.It’s now like a fully rebuilt gearbox !Done over 1000 miles with a 2 ton trailer and I am very impressed with this stuff.It’s totally fixed.Gone from 18mpg to 26 mpg.Highly recommend this product.It is totally magic stuff.

smooth shifter
