ATP at-205 re-seal stops leak, 8 oz bottle, new,

Q: Do I just dump the whole bottle in?

8oz bottle will treat a 6 quart capacity, adjust accordingly

Q: Will this work in Chevy 4L60E transmissions

I was reluctant to put it in my 4L60E, but I did when the leak got pretty bad and I didn't have time to fix it. I only put in 1 bottle when the instructions called for 2, but oh my goodness what a result. Stopped the leak completely in under a half hour. I was blown away... blown away. Thought it was snake oil, turns out this stuff is legit. Then as if that weren't enough... the darn transmission started shifting more crisply... tooootally unexpected side benefit. It has lasted almost exactly a year and now the leak is slowly starting to come back. I have no reservations about treating it again. Since it can't over-swell the seals, this time I'll be adding the recommended 2 bottles. This product is a rare diamond in the rough of snake oil products. So to answer your question, yes, apparently it does work in 4L60E transmissions.

Q: So basically I just put this where I would put the oil and it should stop the leak? Thanks

I have used it on an Audi A6 2014 with supercharged 3.0T 109K miles. There was a really small leak that I could not figure out where it came from (back side of engine, it was not the timing chain covers, maybe the oil filter housing). Anyway, after putting this and driving about 300 miles later it seemed to stop the leak for a few months. Later sold the car for other reasons but I am happy with what this did. It rejuvenated the seals.

Q: Is it necessary to drive the 5 hours at once, or does this refer to intermittent driving? Thanks!

It can be intermittent, Just need a total of about 5 hours, made up of multiple outings. Best to start vehicle (and run at least a few minutes) as soon as possible after adding AT-205 so that it is evenly mixed with the oil.
