Royal Purple Max Gear 75w90 tranny fluid
So I need change my manual tranny fluid. Everyone has said to use Redline MT-90 since our trannies need GL-4 and not GL-5. However the Royal Purple 75w90 says its safe for both GL-4 and GL-5 trannies especially when it comes to copper materials such as our tranny synchros. Any thoughts and has any one used the Royal Purple stuff???
