Not the best ATF but close to it
I used this on a 2004 Chevy cavalier. I had bought the car around 20k miles ago and did a transmission change with ATF and some prolong treatment. Man this stuff is a huge difference - the shifting is a smooth as butter, but with way lower viscosity! It's probably not as good as royal purple or something you could pick up from a racing shop...but it's priced very well and gives very good results.

Great for hand tools and lubrication
I use this for hand tool cleaning and lubricator duty. My ratcheting wrenches get a yearly dip in parts cleaner, then into a jar of this. Good to go till next year. Probably great for transmission. But absolutely amazing for keeping expensive hand tools in good condition.

Good price, older high mileage vehicle
Good pricing, good use on older vehicle. 2004 silverado 4.3 extended cab. Pumped out with suction hand pump, then changed filter and 4 solenoids. Runs like new.
