Some quick background on the truck: It's a 2004 Silverado 1500 Single Cab 2WD and came originally with the V6 motor. I have since swapped in a V8 from a 2006 Silverado 1500 (Including the engine harness and computer) while keeping the original 4L60E that came with the V6. The trans has about 130k miles on it and got a new filter and fluid during the swap.
Since the swap I've been getting flaring in all the gears but it is worst on the 2-3 shift, I have somewhat improved the shifting by increasing trans shift pressures (The tune is otherwise stock) but it still flares noticeably. I have also noticed the TCC is applied all the time when the truck is over 9 MPH regardless of the TCC apply/release settings. I'll attach the tune and 2 logs, one from 'aggressive' driving and one from normal driving on country roads and highways.
Any insight into tune issues or potential mechanical issues with the trans would be great
