4l80E rebuild assembly problem - experts?

[01spirit750]

Hey all. I have been reading the forum for a while and finally decided to post.

I am completing the rebuild of my 4l80e and have a little issue that maybe an expert can help me with.

I am doing the final assembly of the case.

The overrun drum assembly is not seating down all the way. When I install the oil pump it is hitting the overrun clutch and the pump has about a 1/4 gap to the gasket surface.
I believe the problem is somewhere between the forward drum and the center support. I can see that the overrun drum is seating all the way against the forward drum.

I know everything is good upto the center support since the bolt for the center support lined up correctly.

I thought maybe I had installed the intermediate pressure plate installed upside down but I pulled it appart and I had it installed correctly.

I am stumped

Thanks

Check your overdrive carrier and overrun clutches, It doesn't sound like the carrier is seating completely in the overrun clutches. I've had those fight with me before.

Thanks. I pulled it apart Wednesday night. It looks like I did not have the sun gear shaft installed all the way into the sun gears. I have it back together and all is good.
