Remove and install new transmission 904 auto

Here's one everybody forgot: If you are reinstalling the same transmission, take a can of spray paint and mark one ear on the flex plate and also get some paint on the corresponding torque converter tab. The four bolts on the converter only go in ONE WAY and it's possible to get as many as two or three in before you realize the pattern is off and the last one won't go in and you have to START OVER!

If you are installing a different transmission, try to line up the 4 converter bolts with the flex plate before installing it (or by using your old converter with the painted tab). Hell, I'd even rather drop the flex plate off the motor and line up and mark the four bolts than have to do it with the trans in place!
