When I drop the pan how easy is it to tell if the pan lip is straight? I plan on using a 2' carpenter's square, will that work? I plan on using a small bit of RTV to hold the gasket in place so I can bolt it on. What type of gasket to use? Do all 350 trans take the same gasket? I looked at the bolt pattern and it's off a bit from the manual, but has the same # of bolts. Just curious. I could take the pan with me to the store, but would rather not leave the car up that long.

I know, stupid question. How much trans fluid does a TH350 hold? I plan on dropping the pan one day to solve a leak from a bad pan gasket(hopefully that fixes it). How much fluid does it take to top it off? What filter would I use? I could drop it and take the old one in, but would like to just get it done in one shot.
