Mixing trans fluids

[gvr4ever]

Probably a stupid question, but I lost some red line fluid in my trans doing something other work, but I probably have about half a quart of royal purple that I used in my Mustang trans. Could I mix those? I'd just go get red line, but it's Saturday and that just isn't going to happen.

yes, no problems doing so. I've run that same mix twice now for same reason

 

[BoostedAWD91]

yes alot of people run mixes of Syncroshift and Redline gear oil

I am running synchroshift and redline. In fact I called redline and ask them if you could mix and they said it was fine in fact they reccomend it for our transmissions.
