Lubegard60902 Automatic Transmission Fluid Protectant, 10 oz

I came across this company by accident. On YT folks were showing vids with their other product for transmission shutter, in the lockup clutch particularly. In my application the rather new AOD in the hot rod seemed to have a vibration. Since this company has SO many different products and the AOD was made over so long of a time I called them to inquire as to what might be the best product to use. They did NOT try to upsell me, they just went through some Ford service bulletins and made a suggestion based on that. We put some new Mercon V plus new filter and two of these 10 ounce bottles in the trans and the vibration, for as much as we have driven it so far, seems to be totally gone. My friend used the other product in a Honda and it worked instantly too. I look forward to many trouble free miles with this product.

I had torque converter shudder in my 2015 Silverado. I added 2oz and drove my truck for 30 minutes and the shudder was gone. I am going to pull my boat this weekend and make sure this cured all the shudder. Can’t believe how 2oz could fix a problem the 3 Repair shops could not figure out.

This stuff works. I am using this for every single transmission fluid change I do from here on out. 2005 GMC Yukon XL Denali and 2012 Jeep Wrangler - both vehicles with over 157k miles on the odometer...

My 2011 Honda CR-V has an issue with torque converter shudder and occasionally shifts quite hard. Despite my best efforts changing the ATF every 3rd oil change (15,000 miles or so), it was getting worse with harsher than normal shifting and worse shuddering. I added 6 oz of this additive to the transmission after a fluid change and it did wonders with the shifting issues. Shifts far better now. It did help the shuddering some but it did not get rid of it, but I expected that since at this point the torque converter clutch is probably too far gone to save it. Good additive Ill be adding some every fluid change now to nurse the transmission along until I can afford to replace it.

Good stuff, lubeguard in general provides addition friction modifiers for improved shifting and increased transmission logevity.

Up sifts and down shifts improved considerably. Much smoother operation and downshift " jerk" is gone. I also changed transmission fluid twice to ensure clean and fresh fluid. 354K and still running.... Toyota!

Did a transmission filter and fluid change dropped this into it as well. Can't say anything bad about it. It's universal for most transmissions you won't really know it's working but itll help. Little peace of mine to keep that bad boy running. I have a 2012 tahoe LS.

Works great. Had a hard shifting between 1st and 2nd gear especially when the car is cold. After adding this it was much better. I’m actually surprised at how much of a difference it made. Highly recommend
