Question LS engine with th400 oil pan install

I figured since all the heavy hitters are in this thread and use setups like this. I need to know how everyone is installing this setup.

ON a ls engine with a ls trans you need to align the trans and engine first then install the trans for proper fitment. But when you use a th400 does it matter at all when you install the oil pan and how it sits?

What is needed for this to work and NOT leak or mess anything up?

thanks

I just basically eyed it. LOL. You can see one of the holes in the block through the oil filter hole, so I lined that up best I could, and tightened her down!

Get them as close to the bellhousing as possible and lock it down

You only do that because you need to have the engine flange and pan flange on the same plane with a full bellhousing

Old open bell on bottom doesnt make a difference

line up the pan with both the front and rear cover PERFECTLY and lock it down.
THe 400 trans has nothing to do with the alignment for this setup.
It will only use 6 bellhousing bolts as well. Since the rest of the bolts are useless and wont work

I just bolted mine right up. Went on with no problem. Just line them up and get two bolts started and tighten it up.
