Easiest way to replace a trans pan?
After hitting a curb about a month ago my I30 has been decommissioned as my daily driver. The pan got completely crushed up into the valve body. Thinking it would be an easy job I purchased a pan and gasket. When I took the pan off (after bending the metal to expose the bolts) I soon noticed that the wires for the solenoids had been severed delaying my repair even longer. I went to the yard and pulled this part of a Maxima and then reassembled the valve body.
Today, I went to go put the pan on and I am having one heck of a time getting the gasket to stay in place when I bolt the pan on. What are some tips and tricks you have done to get this done?

Try Permatex #2 (I think) Gasket Cement. It is about the consistency of toothpaste, and will hold the gasket in place. In thinking, they have #2 and #4 (again I thinkl) and one acts as like a glue, and the other allows separation down the road. I would probably use the one that allows separation...just in case.

In different corners screw a few bolts halfway just to hold the pan up there. Don't use permatex on these bolts. Using a screwdriver get the rest of the bolt holes lined up with the gasket holes. Apply permatex to about 4 bolts at a time. Tighten them in place using only 7-9 lbs of torque. Too much torque will split the gasket. Take out those first bolts you screwed halfway and reinstall them with permatex applied.

The first time I did a trans pan the Napa guy told me to put just a dab permatex around the bolt heads. I did that and never had a leak.
Whether it was instrumental or not I'm unsure. But no leaks. And I've done it that way since then as well.

If you are using new bolts it won't be needed because they already have sealant applied. If reusing the used bolts then don't take a chance. Having very little tightening torque those tiny bolts will loosen over time.

Was referring to Permatex thread sealant. RTV isn't the only sealant they produce.
