2009 avalanche shifting weird
My 2009 avalanche LTZ will not shift to manual mode and tow haul mode doesn’t turn on. When I step on the gas pretty hard it seems like the transmission down shifts to much because the rpms go way up but the trucks speed doesn’t increase. If I am easy on the throttle the truck shifts perfect. The abs and traction control lights are on and I just replaced the front wheel bearings thinking that might be the problem. Does anyone have any ideas on what is going on with the shifting???

Still at 198000 miles an 9 years. even if serviced on time, you dont know if the transmission was abused, overheated and so on. It's likely going to need to be rebuilt or have a rebuilt unit installed, IMO. You can also live with it until it finally fails to operate which could be a few years if driven lightly.
