The previous owner of my 94 civic hatch with b16a swap told me he used 5w30 motor oil instead of transmission oil. I need to change her fluids before I leave and I was wondering if this was okay, swapping oils. Will this harm my tranny?? Should I go back to using transmission oil?? Wht oil do you guys recommend?? Thanks in advance for all your help.
btw she is a stick shift!!!
