Did a complete flush and replacement with synthetic fluid in 1999 Mercury Grand marquis, and in a 1995 GMC 3500 454 CID with the big towing tranny. Had 13 quarts in the Mercury and 17 in the GMC. Used this in both for an hour before changing.Shifting improved remarkably in both…..something worked.

Does what it says. I use it it everytime I do an oil change now. It really helps to breakdown that stubborn sludge stuck in my Chevy z71.

I purchased this to flush the transmission on my 2004 Honda Accord that need transmission fluid change. It was shifting rough so I decided to do the flush to get it cleaned out before pouring in new fluid. Now the transmission work very good and no more rough shift, had to put Lucas transmission fix with valvoline max life full synthetic transmission fluid.

This additive drains out all the crap from your Transmission & clears the way for the new transmission fluid. I noticed an immediate improvement after putting new fluid in it.
