Lubegard 19610 Instant Shudder Fix

For those wondering, I'm just an average Computer Nerd kind of guy, not really a car guy, but I do most of my own maintenance on everything! Being a very Technical Computer guru, I'm always cautious when it comes to "Quick Fixes in a bottle" kind of stuff. I guess that is the analytical side of me kicking in all the time and it usually serves me well in the computer world, so I really didn't have much hope for fixing my 2001 Lincoln Town Car with about 91,000 miles on it. The car started "Shuddering" a few years ago, and like most folks, I had to eventually replace a "COP, Coil on Plug" device. About 8 months later, the Shudder started again, and this time a dash trouble light came on and the code indicated a bad COP device, so I had my mechanic replace another one that was found to be bad. At $200 buck a wack, this was getting expensive, so when this Shudder came back a third time, I decided to replace all of them as well as new plugs and wires. This worked great for a few months but then I got a "Different" kind of Shudder, and it only seemed to happen when shifting at speeds over about 35 MPH, and applying a little more gas pedal did not get rid of it like it did with the original COP based Shudder I experienced. In fact the engine was running smooth as glass, and it seemed like the car was trying to go into OverDrive locking transmission mode when this happened, so I was really confused. Lifting off the gas pedal then getting back on it seemed to make it stop, but then in a few minutes it would start again, particularly when approaching a slight grade up in the road. This car is used mostly in town, so speeds are slow, around 30 - 50 MPH when this happens. Out on the highway, the problem is much more pronounced. It seemed like the OverDrive would engage and then disengage very quickly and often would feel like you were driving over the little rumble bump strips on the side of the interstate at high speed. Doing a little research on the web led me to try this product as it made the most sense, and was certainly reasonably priced. So I ordered it from Amazon, and incredibly, it arrived the same day!!!! (Great Job Amazon!!!!!) I kind of stuck it in the corner for a few days, and this afternoon when my wife came home from the grocery store, she was complaining about the Shudder, so I went out and poured in one tube of this "Instant Shudder FIXX" into the transmission via the dip stick filler pipe and decided to just take the car for a spin and see if this was all it was cracked up to be. I don't impress easily, but WOW !!!!! WOW !!!!! WOW !!!!! I pulled out of the driveway onto our two lane 35 MPH road and drove about a mile with NO SHUDDER!!!! I turned onto HWY 17-92 and headed for Interstate 4 which is about 4 miles away. Speed limit on this road was 40 for about 2 miles, then 50 for another 2 miles. I got on I-4 heading East and accelerated off the ramp onto the highway, set the cruise control for 72 MPH, and let her fly!. After encountering several hilly areas where the car would have to work a little to get up, I exited the highway and took a few backroads all the way back home. Speeds ranged from about 30-55 MPH. This car shifted and ran smooth as silk!!!! Not a Single Shudder or pause during shifting during the entire trip!!!! I'm Absolutely Astounded with how well this product works!!!! Like I said earlier, I am very pessimistic when it comes to Miracle "Fixes in a bottle" products, but honestly, I still can't believe how fast and how well this product has worked in my old Lincoln Town Car!!!! I figured I had nothing to lose, and really didn't want to spend money for a whole new transmission for this old car and was going to trade it in for something else because the erratic shifting was just driving me crazy, particularly out on the highway. Wow, what more can I say? Anyway, if you have an old Lincoln Town Car that has a similar Shuddering problem and you are sure it's not the COP, Plugs or Wires, you owe it to yourself to give this product a shot!!!! If anything changes, I'll definitely update this post, but for now, this car is running as good as it did the day it left the showroom!!! Truly Amazing!!!! Thanks Lubegard for creating the "19610 Dr. Tranny INSTANT SHUDDER FIXX", This is a FABULOUS PRODUCT!!!!!!!!

2015 Infiniti QX80 with 134,000 mi. I had already flushed the transmission fluid three times and I had already cleaned the filter by dropping the transmission pan. It was still shifting poorly and kind of "hunting" for the right gear. The Little tube was hard for me to get it into the transmission as you have to fill my transmission through a hole on the bottom. So I felt like I got about half of it on my hand and maybe half of it actually in the transmission. Anyways holy crap did it actually work, I drove the thing for 20 minutes afterwards cuz I was still dumbfounded how well it was shifting again. I don't know how to describe it but it was no longer shifting unnecessarily and it was very smooth at all speeds. Totally worth the $20.

This is really good stuff that was recommended to me by a trusted mechanic friend who used it several times in his trade to fix several of his customer cars. I used this in my 2010 Honda Odyssey EXL with 130K miles for which I did a transmission flush when it crossed 100K miles and after which I noticed a slight hesitation in the transmission after the initial start. I used one tube of this product mixed with a little bit of transmission oil and poured it in through the dip stick and took it on a drive. After driving about 5 miles or so I noticed an instant improvement in the way the car drove especially uphill where it was previously hesitating is now became very responsive. The car itself drove super smooth and my buddy who was in the passenger seat also noticed how smooth the car was gliding on the highway. Highly recommend this to any car that has crossed the 100K mile mark. My buddy suggested not to use more than 2 tubes at a time depending on the intensity of the problem and add it every time the transmission oil is replaced.

For my issue, the instant shudder fix did the trick. Between 40 and 60 miles per hour, if I lightly accelerated, I would hear a groaning vibration sound. If I accelerated firmly, the sound was not there. It sounded like I ran on a rumble strip for just a couple of seconds. The transmission is a Ford 6-speed 6R80E transmission. I applied two of the lubegard 19610 instant shudder fixes to the transmission, and I no longer have the sound or issue with the torque converter not locking. I am about 20k miles from a transmission service (150k mark). So i will go ahead and have the transmission serviced soon. I will add one instant shudder fix at that time to ensure I have no further issues.

works well

2003 Civic lx: drained and filled transmission fluid 3x, and finished the last fill with this little tube. The torque converter shutter has been greatly reduced, to the point I could be confusing it with road topography noise. Shifting has also improved and the greatest improvements were only after including this fluid to the mix. Outstanding stuff.

Great product for Honda automatic. Shifting like a dream.

otimo produto ... resolveu

Made a lot of difference to the knocking and studder

Mi coche comenzó a dar pequeños tirones cuando circulaba a baja velocidad y pisaba acelerador, las RPM oscilaban, como si el convertidor no estuviese funcionando. En un grupo de Facebook me dijeron que el problema venía de los solenoides que controlan el embrague del convertidor de par y que probase este producto. El primer día fue un poco decepcionante, pero después de 200 kms era otro coche. No había tirones ni oscilación de las revoluciones. Tan fácil como echar el contenido en la caja de cambios y dejar que haga su magia. Recomendable al 100%. Recomiendo visitar la página del fabricante, tienen productos para cajas de cambios y creo que es muy interesante. En cuanto el producto vuelva a estar disponible, compraré otro vez porque creo que puede volver a pasar, ya que creo que la reparación definitiva sería cambiar los solenoides de la caja de válvulas, pero si puedo alargar el trauma económico de cambiar la caja de válvulas, mejor. He tardado más de dos meses en escribir la reseña porque quería asegurarme de que el producto funciona realmente, así que ahí va mi opinión.

Worth it
