If you have an aging Subaru transmission, this may buy you time
First off: unless you use Gear 300, never use a synthetic in these older boxes. You will experience synchro grind and when that happens, your options are limited.This product helped me when I made that mistake. Since I live in a colder climate, I wanted to get away from running a conventional gear oil. Walmart used to have a semi-synthetic that worked great but they no longer make it. After making the rounds of synthetics, my synchros were not happy with me, the only thing so far that is working is a straight gearbox full of this. Time and temperature will tell if this truly does help.

Edge ST shudder fix
I have a 2019 Edge ST with 32k miles. Ever since I bought it, it's had a shudder on tight turns that seemed to be coming from the rear diff. I got some of this and drained and filled with it and my shudder noise is gone. The blue color is nice too. Quality product that I would highly recommend.

Fixed 4th gear grind in 2002 wrx 5spd
Fixed the infamous 4th gear grind. Order 3 bottles of the lightweight just in case(ended up using 2)and one bottle of motul 300 75w90 full syn fixed 4th pretty instantly. Trans whine also slightly went away for 2nd. Glad I can bang 4th 😎 if your wrx having the same problem I’d give this cocktail a try if it isn’t too late.

Got a STI 4th gear grind?
3 of these, 1 75w90 and after a few drives it got rid of the 4th gear grind in my 2016 STI. Read about this on Bader Built's YT channel and gave it a shot. Glad I did. Mine was bad so I did 3 shockproofs. He does say if it's not that bad to do 2 and 2. But that's your call. If you got a grind, try this first before looking at getting synchros changed.

Great customer support!!
I changed the gear lube in the PTU of my 2019 Ford Edge about two weeks ago. Had no idea which Redline product to use so I emailed them. In a few hours I had a reply. I have been using this every since. Only been two weeks but so far so good.
