Torque converter too tight against flexplate
Torque converter too tight against flexplate 98 A4 yank converter stock flexplate LS1
I blew my engine and picked up another.
I was installing the new engine and normally I have been having to put a washer between the flexplate and the converter, but now they are so tight the engine will not even rotate.
What could be wrong?

Yes, you can put a straight edge over the bell housing and measure the distance down to the mounting pad on the converter.
It is pretty much the same for most GM transmissions including 4L80E, might be 1/16" different for some, but very close to 1-1/8".

Here is a good article. I haven't done one, but this is a great how to.

Well I think I found the problem. I pulled it back out and I guess I did not tighten down the flexplate bolts. 
I can't believe I did that. The converter was all the way in as far as I can tell. Do you think it did any damage?

Then once the trans is bolted up to the engine the converter gets slid right up to the flex plate . Correct?
You measure the converter installed into the transmission.
Then you measure the distance from the converter to flexplate, with the transmission installed and converter all the way in the transmission.
I have videos online that detail this but can't post here.
