How should I check fluid level on auto trans (GM unit)
I have a simple question about checking fluid level for the GM automatic trans. As most of you know there is no dip-stick for checking the fluid level. You have to check it at the fill plug underneath the car. I keep hearing that it needs to be setting level to be checked which seems rather obvious. But the I look and realize that the chassis and the base of the trans are setting at different angles. So which needs to be setting level? or the trans? I've seen it done on youtube where the mechanic checked the level along the lip of the trans fluid pan where it meets the trans housing. Others were less descriptive and just said it needs to be level and seemed to be refering to the chassis. Just want to make sure I'm doing it right.
