Another thing to check is the MAF sensor. If the MAF sensor is dirty it will report the incorrect calculated torque and the TCM will go into a protect mode that will feel like someone slams on the brakes when you are coming to a stop, especially into 2nd or 1st gears.
Go to any parts store (advance, autozone, pep boys, etc) and get some "MAF Cleaner". Remove the MAF from your intake and spray it down really well, especially into the little openings in the MAF. Let air dry which only takes about a minute, re-install and test.
The MAF's on these cars tend to get a little dirty and will cause the issue you are having, try it out.
Hope that helps,
