4L80E possibly catastrophic problem ?????

[Botlfed]

so i pulled my 80e out to put in my 3200 converter i recently bought, i dropped my trans put the converter in put the trans back up hooked everthing up the same way it was, had to shim the verter, amd change flexplates cus the snout on the verter was to big around for my stock 5.3 flexplate with the spacer in there. well now the trans whines pretty loud, if i take off slowly it wont do it but if i give it some gas it whines thru 1st 2nd and sometimes 3rd and out on the highway you can barely hear it, it shifts fine, even stalls fine but im wondering if any of you guys have had this issue or know what it could be. possibly to much fluid maybe or not enough???? front pump maybe but would it still drive fine??? i went and did a WOT on it and everything is fine just whines like a damn mountain motor. any ideas before i drive 8 hours to san antonio in 2 days.
