Can this fix up transmission shudder ???? 

I can confirm this100%! I drive a 2014 ford explorer. The dealership I bought the vehicle knew about this issue and thought it needed a transmission replacement. after doing se reaserch and adding shudder fix it went away after driving it around for 5 miles. Going on almost a year now and it hasn't came back! Thanks for putting this video up and sharing your knowledge ( as a auto technician myself) it's crazy how quick and easily people can misdiagnose vehicles and jump the gun on changing parts rather than doing research first. Even after graduating from tech school in 2012 you never stop learning and reaserch is key before even turning a wrench, it can save you big time.

2017 Police Interceptor Utility (Explorer), 3.7 NA, 6F55 Transmission 130k miles. Did the same as your customer, changed valve cover and intake gaskets, spark plugs, and coils - no improvement to the shutter but acceleration felt the tiniest bit better. Plugs had some rusty looking corrosion from the tip through the threads. Did a drain and fill on the transmission, got out about 4.5/5qts of fluid. Replaced with 5qts Mercon LV and 2 tubes of Lubeguard shutterfix. Issue is 95/98% of the way gone. No more harsh shuttering, still tiny variations in RPM below 45mph when the torque converter isn't completely locked yet. Never had issues during full throttle accelerations but the 1200-2800rpm range, low throttle, up to 45mph area was the zone of concern I was targeting. I have all the work orders done on this car from back when the police department had it. They've been using 2 units of Lubeguard each time and the fix seems to last for ~10k miles at a time, and they did it 3 times before quote for a new transmission was ~6k and they sent the suv to decommission and auction. Definitely need a replacement torque converter but it's impossible without removing the entire powertrain - TC runs ~400$ for a remanufactured, with labor it would probably come out to ~1600$. Plan on doing this till it completely gives out or I sell it.

Your killing me saying Turk most of the time! Good video

That was great! Simple fluid change. Routine maintenance wins! I remember the Honda's with the CVT transmission when they first came out. They had a low speed shudder and Honda came out with a fluid update that cured it. Good one OZ!

Audio is back. Thank you Oz. Happy Resurrection Day.

All your video's are great but I really enjoyed the before and after with the computer. And the bumps lol. You make things so easy to understand. Thank you for all your efforts. Happy Easter. I hope tomorrow isn't too hard on you.

Absolutely the best video ever on this product. Thank you 👍🏽

the Lube guard snake oil FIXX really worked on my 180kMi Acura TL. super well worth it

Good one, nice to see the before and after scan data 👍👍

The most notable item that predicts shudder was the torque converter clutch pressure. When it was relatively low, say, ~35 PSI, it would shudder. When it climbs past 40 PSI or so, it would go away. This tells me that, for whatever reason, the transmission wasn't able to generate sufficient pressure to make the torque converter clutch grab as hard as it should have, thus causing intermittent slippage, which manifests as shudder. At least, that's what appears to be going on to my untrained, amateur, shade-tree mechanic eyes.

Great video, explanation and testing, Azael. Easy to follow and made total sense.

Clear as day , nice explanation .

I've been living with a shuddering transmission in my 2012 CR-V for about 5 or 6 years. I had taken it to a mechanic and he told me not to worry about it, that it would last many more years. I loved the CR-V but this shudder was driving me crazy. So, after reading lots of reviews, I ordered Instant Shudder Fixx and put it in my transmission 2 days ago. Afterwards, the wife and I took a 20 mile trip and there was not one shudder. Not even a hint of one! In the future, if I ever have a vehicle that shudders I know what to do. Instant Shudder Fixx is easy, quick and effective!

Thanks man-great video! I sell oil for a living and always love learning more!

Thanks Oz great video 👍

@scannerdanner called this stuff “Dr Shudder Fix” in a video he made last year. It was hilarious because they were so skeptical and it made them feel like they were less than professional to call it a fix. Since then it spurred an ongoing joke where they call anything related to a chemical fix “Dr ……… Fix”. “Dr Connection Fix” etc…. I love that you took the extra steps to prove it. Well done Azael.

Used it on my Transit Van with 386,000 miles on original trans. Shudder completely gone!!

Didn't even know torque converter slip was a thing, LOL! Thanks for teaching me something new, Mr. Oz!!!!!! Rock on!!

Great video

Thanks Oz, this stuff is mandatory if hauling a car load around of bbws.

Muchísimas gracias primo por compartir su conocimiento y tiempo . Dios que continúe bendiciéndole. Una pregunta a un mstg daño el perno del torque convertido compré uno de junk yard y ahora marca código de tc . ¿ tiene idea por qué ? Le agradezco su respuesta

Great video did it vibrate all the time or just in gear/driving so will it work even wen the car is at idle

Would in be explained as a pump? The engine spins the converter which sucks up trans fluid then expels it under a higher pressure. This higher pressurized fluid is pushed against valve plates which make clutch disks come in contact with their drive plates which causes the main shaft to spin which the pins the wheels via differential.

It did work on my 2009 Subaru Tribeca with the 5 EAT Transmission, I did a full fluid flush using the OEM Subaru Fluid via transmission cooler lines to get all clean fluid into Transmission and the shudder was bad going uphill, There is a TSB from Subaru with the 08-09 Converters with Subarus of this vintage, However between labor and parts it's an expensive fix, So far it has not done it since I added this additive, No idea how long it will last, I'm hoping between the clean fluid and the additive it will be ok for a little while.

Hi Oz. Another great video! Remove the transmission to change the the filter?? Ford has a better idea 😆

Awesome

have you ever tried the ford skunk oil

Awesome 👏

This is why you change your fluid every 60K or so!

tks

Is his good for a 2017 toyota camry?

Where can u buy that stuff ?

How long until the shudder came back though?

What if you put this in your transmission and you find out it is a misfire will it screw up your torque converter?

Thanx bro

Reset adapteive learn with high end scan tool.or forscan.

Pense que solo pasaba ami que El audio no aparece enseguida en RU-vid cuando subes un video 😮

Mine just started shuddering last week. And I can feel it shudder bad at 35 to 45mph

I think you made the big difference with the fluid change but if the additive worked, is it just a temporary fix? My bet is that it is but it will be interesting to find out. Oz, you been watching Scanner danner haven't you? 🤣🤣

Miracle Juice

30k miles since I put it in and still shifts smooth as butter.

I didn't know Fords have turk converters. Did you know vehicles don't have parking brakes, they have e-brakes?

I would have liked to see the results with just the fluid change and then see the results with the additive.

Where can you buy that stuff ?

how many miles old oil?

What exactly does changing the motor oil do for a transmission? Transmission and motor oil are two completely different thing.

BAD OIL,BAD OIL.

😂good...job...😂pooow
