need help with 4l80e swap

[Custom 68]

hey all I am stumped. I am doing a 4l80 swap and it wont work so I need some help diagnosing. I have found a second tune with my same os and am going to try the segment swap again in case the first one didnt go correctly. I am also looking to find what else I can diagnose. on the wiring I swapped the wire on the U into the S position and have ISS in my scans.
what seems to be happening is the transmission starts out in first then immediatly shifts to second then even third according to my log even when I command it to stay in first. The transmission seems very "loose" like it is in second. The converter is a 2500 stall. This is a Bowler trans but has sit covered and filled with fluid for a little while but is basically new.
what should I check? I have not checked for power or anything at the trans.

included is my tune if that helps. this is a hptuners file I changed the extension so I could post since I wasnt sure how otherwise.
thanks
Dave
