    It does work. A lot of Fords had a tranny shutter and this stopped it.

    But only on vehicles where u can add to the transmission. Many newer vehicles have eliminated this.

    like mentioned above, Ford still uses this on shudder issues.. Its not going to hurt anything. Sometimes takes care of it sometimes doesnt, if not you got bigger problems

    If I recall the auto parts store where I worked sold something similar made by the same company in the late 70's. I was on the same shelf as STP.

    only thing that helped the issue with my gmc is a complete flush of transmission oil. Common issue with 14-19 GMC models. Something with air getting into system and breaks down the oil.

    With the 8 speed, It was the first try at synthetic trans fuild. And they missed it

    I took care of those problems 17 years ago when I moved on from Detroit vehicles and purchased a Tundra.

    Yep. GMC flushed mine at 20K miles under warranty when it developed a shudder. Now has has 48K on it and the shudder has not returned.

    I had just bought the truck from them new two years earlier and they were aware then that the vehicles with the shudder were made in Mexico and had the wrong fluid installed. Like mine. I kind of busted their chops a bit asking them why they didn't change it before they delivered it to me? Any kind of a shudder is probably making metal some where so why did they wait until I had the problem? They had all the canned answers. I think they were just hoping I would make it past warranty before having an issue so they could bill me the $400 for the flush.
