I'm not sure what the spec is on GM, but on Ford, they do not use the MAF for TCC lockup modulation. Ford also did not continue use of a MAP sensor. They are looking for TP voltage to drop below 1.2 volts or go above 3 volts or a high signal from the brake circuit. GM should be somewhat similar. This is a fairly common complaint on GM vehicles.
