Redline/Amsoil Transmission fluid
Are the fluids for the transmission the same as the fluids for the transfer case and rear differential?
I have an Evolution 4, and the service manual states that I use 75/85 Dia Queen Gear Oil for the transmission, and that I use Dia Queen Super Hypoid Gear Oil rated GL-5 for the transfer case and rear diff.
I know I don't have to use the Mitsubishi brand Dia Queen, but I am stuck as to whether to get 2 different oils for the trans and the transfer case and rear diff. Is there a huge difference? Or am I best just to do what the manual says?
Thanks in advance
Also, apologies, I just realized these are the Evo X forums

This is good to hear, as I just bought 3 quarts of Redline MT-85 for my 03 Evo, which just clicked 111,000 miles on the odo. The previous owner used standard 75W-85 Gear oil mixed with lucas, so lets just say the trans isnt a happy camper shifting in 30* weather. Cant wait to get mine changed now.
Amsoil has worked great for me so far. Just changed it 1 month ago for the second time. When warm, this fluid makes shifts feel extremely smooth. However, I do now let my car warm up for a few minutes before driving in 30 deg or below weather because cold Amsoil does make the car a bit notchy.
