First off how many miles? What are you talking about spooling?
Mine would try to go like the torque converter was trying to lock up with it in drive and foot on brake pedal. Turned out that the tranny had initiated it self destruct mode and it cost me about $3k to get fixed (have to rebuild/replace tranny).
Also you need to get rid of the superchip, they are hard on the tranny, and get a SCT.

The superchip has been flashed off , i beleive it screwed the line pressure solenoid up , now after a few weeks of driving regular , it tends to pump pressure up everynow an then almost like a hiccup. i just drove it home from my girlfriends and the overdrive light started flashing an the it seems to not want to shift from thrid or forth to the next gear an keeps its self at 3gs, im going to order a new modified valvebody with solenoids and have my mechanic do a tranny flush, any idea guys , its starting to eat me up inside i love the truck to much to just bail on it the tranny has 190,000 on it same with the motor its all stock , changed the fluid an filter the fluid was a nice red not any color didnt smell burnt or anything an the filter was clogged figured that could of been the problem but its starting to act up again this time worse any ideas
