Hi Eric ,
I remember seeing you do videos and have commented on too much rtv on gaskets and it being difficult to clean up and making a mess everywhere .
I did a transmission service on my th700r4 transmission and found a way to hold the gasket in place without using any rtv or sealant at all.
The way I did this was to use breadties .
the pan gasket was placed on top of the pan and a breadtie inserted in all the 4 corners and twisted them to hold down the gasket in position.
The pan is placed in position under the transmission and all the other bolts are started a couple of turns so that there is clearance to remove the breadties when you are ready to install the last 4 remaining bolts in the corners.
if you think is a good idea then please make a video about it .
