Default 15 Sierra 6 speed

Hey guys,

Got this 15 sierra with a 6 speed making a terrible whining sound. Anybody know a good shop in Houston that can work on the new 6 speeds.
Ive been looking around and can we make upgrades on these trans? Aside from a stall.

Houston Automatic Transmissions on 249 has refreshed and rebuilt our fleet trucks. Those trucks usually cross the 250k mile mark before needing anything done.
