Okay, so I accidentally put in a quart of Redline 75w-90 GL-5 in my transmission. I was pumping in Redline MTL, MT-90 and I accidentally grabbed the GL-5 by accident and didn't realize I had done so until I saw the MT-90 sitting there. Right now as it sits the transmission has one quart of MT-90, MTL, and 75w-90 GL-5. My question is will it be okay to run the transmission like this? Or should I drain a quart and add the remaining MT-90 into the transmission? Any advice is appreciated, it was dumb of me not to check the bottle beforehand but I rather not buy more redline fluid cause it's quite expensive.
