Use this in Ford 8" and 9" limited slip rears
The product has a really obnoxious odor, however it really works! The gear oil I used had friction modifier in it but didn't correct the grabbing/ locking in the limited slip differential. One 4oz. bottle of the Ford friction modifier fixed 90 percent of the issues inside of 10 miles! After doing some figure 8s in a parking lot I suspect all grabbing will be gone.

Used on 2003 Mustang Mach 1 8.8 Ford rear end.
Works great. I just put it inside the Valvoline bag as it was halfway full and poured it all in. Its a green color additive. Seems to work as intended.

solution to chatter
put this along with lucas gear lube in a 2013 f-150 rear end that prior to this service sounded for all the world like it was going to explode at any time. Other lube changes with other products made no difference, but this combination solved the issue completely.

This is a bottle of magic!
No more Ford power steering whine. No more shutter on a Hyundai transmission. I've purchased this product a few times. Use the while bottle for trans or diffs, everywhere else you can use sparingly. Highly reccomend... its magic in a bottle. Just DON'T smell it... worst smell ever that lingers

Works well but massively stinks
We had some slippage in our TC for a 2015 Porsche Cayenne, changed TC fluid and added this. There has been a no signs of slippage after the change and addition. Will continue to monitor.

This is the stuff if you have issues w/ your higher-than-stock drive train.
I'm not much for "additive" stories. But I 1st used this on an old, chattering positraction (trans-axle). Problem solved. Since then I've used it on Jeep transaxles w/ the same success. It can't repair worn parts or reset alignments or tolerances, but there's something intelligent living in this fluid that finds the problematic areas and compels them to play ball *The modifier-from-hell* (you'll understand when even your dog avoids you for a week). I've used this product & "Ford CM19546A1 Friction Modifier" interchangeably after doing a bit of research a while back.)
