DR LUBEGARD AUTOMATIC TRANSMISSION INSTANT SHUDDER FIX 6 PACK

It says specifically not to use with Ford type F transmission fluid. I believe this is because type F does not have any additives or friction modifiers, it's just mineral oil. That's supposed to make old Ford transmissions shift very firm. And this product is literally just an additive and friction modifier package. I have a 1977 Ford with an FMX trans. It was acting up, not shifting, getting stuck in second gear. Found a worn band, replaced it, everything else inside looked fine. Still the trans was really lazy about shifting. Sometimes would get stuck in second, most of the time did not want to upshift first to second. When it did upshift it was extremely slow / long shift. I bought these to use in other people's cars (modern cars), but I figured I'd be a guinea pig. To my surprise, it helped a lot. Shifts are still long, but much improved, and always on time. Never gets stuck in second. It took about one week of driving to fully get to this point. It has been a couple months since, and not getting any better, but also not getting worse. Again, it says not to use in Ford type F, and I understand why, but I took the risk and it paid off. I have used in other cars with mixed results. It is just oil, after all, it's not going to fix broken parts or severely worn clutches. But it does what I expect it to do. Will keep buying these.

all good no problems thanks

yes. i added into my 4x4 360000km suv car and it worked very well . shifts gear bit better and smooth. cant make your transmission brand new but still worth using it. twi tube at a time.

shutter fix works good

Wow is all I have. This stuff really works. Saw some good reviews so thought I would give it a try. I was not expecting much but I’m absolutely amazed.
