at the time when allen did my tune he tuned it for the stock trans w/ vett servo and took away 60%tq management. i've been running this tune on the built 60E for 5k miles and now it doesn't want to lockup in 3rd or OD. like i said there was some evidence of contamination in the fluid but i don't know what it's from. i droped the truck off at the trans shop this afternoon. he said the first thing they are going to do is run the scanner and then drop the pan to see what it looks like. i'll keep yall posted. thanks for the replies...
