Bought Clean SSS / Muffler Delete Causing Trans Mushy Shifts?

Hey all,

I bought an '03 AWD Silverado SS about a month ago. Only 136,000 miles for $12k and she runs great, or at least did. Trying to figure out if my recent muffler delete is causing the trans to have mushy shifts. It was a home hacksaw job from a buddy of mine just for fun but I've never had issues with muffler deletes in the past. I'm taking it to get a Flowmaster Super 40 or 44 put on next week hoping that solves the issue. 

Has anyone else ever encountered this? Would lack of back pressure on the LQ9 make a torque difference?
