I have had my 2002 Bravada in the shop numerous times for the locking of my awd. The fluid was changed in the transfer case (no help), the module was replaced (no help) and now the whole transfer case is being replaced. The cost is between 1500 and 2000! the vehicle has 80k miles. This is a very serious issue (and it appears that gm is aware of problems-based on TSB's online) especially in northern climates with snow. The control of the vehicle, when turning is lost, as the particular wheel locks up. I also had my fan clutch break, separate from awd problem.
