Super Transmission Slip and Shudder Fix
I have used this product for years and it is one of the best products I have ever used to help reduce and eliminate transmission fluid issues. I highly recommend it to anyone that has transmission slippage and shudder. It is not a fix if you don't change the dirty or burnt fluid first.

Gods gift to man in the form of a red tube
This isn’t your typical “pour in and go” fix you see on store shelves that makes you wonder “how long will this keep it going?”. I’ve personally put this in my step mothers vehicle which was shuddering pretty apparently between gears, only to have her drive on it after using Shudder Fixx on it for 5-6 years, her selling the car, and the lady she sold the car to also having been driving in it for the past 2-3 years. This product is a welcomed surprise in the ocean of false promising, quick fix garbage you find everywhere nowadays. I have used this product in GM and Ford transmissions (non cvt of course) that have been nothing but problematic off the line, and weren’t in a position to swap out torque converters or in some cases, complete transmissions. Between the older Acadias and their garbage transmissions, the newer GM 6-8 and 10 speeds that are also hot garbage, Ford and their escapes and fusions, all of these extremely problematic and expensive transmissions, as long as it was a shuddering issue was for the most part resolved after using this product. If you have other issues like heavy kicking or jerking that’s a different story and I can’t really cosign the effectiveness in that case.
