My truck is tryin to act like a standard trans. When I go to stop the auto trans will not shift back down, but will choke out just like comin to a stop light with a standard and brakin with out the clutch. When I take off the truck lugs real hard then at about 7 pounds of boost it will pick up. Has anyone had this problem before, my trans. has been rebuilt about 5,000 miles ago, and the only thing I have changed lastly is unplugin the map sensor on the comp and stackin the superchip, but it been runin fine for about 2 months untill tonight.

Any help word be greatly appeciated.

TCC will not unlock. Most likely it`s the TCC solenoid.
