I bought this 2005 Avalanche Sept.29th 2005 (brand new) & I have around 47200 miles on it & have not had any transmission problem with it before yesterday...when I put it in drive & normally start driving & the transmission starts shiffting gears, it shiffs from 1st to 2nd just find but as the speed increases & it wants to shiff from 2nd to 3rd it doesn't ever shiff, its like it goes into neutral, the engine speeds up like its in neutral, I called roadside assisstance & got a wrecker to haul it home, its ok in reverse & forward as long as it doesn't have to shiff into 3rd gear..of course Mfg. warranty is out & I was in the process of buying an extended warranty but even if I proceed in buying said exteneded warranty it won't cover this incident.......
I had the same problem, its the torque converter. I took my 05 c/a in because i was having shifting problem, the long and short of it is there is a breather on the tranmission that sucks in water from the road. the water and the atf dont mix. the dealer put in a torque converter and changed the fluid and installed a redesigned transmission breather.
Crawl under the truck and look at the linkage make sure the linkage is not bend or broken

Transmission just started acting up. Shifts fine up to about 30mph then won't shift into high gear. Stays about 3000 rpm because and won't ever shift. Transmission fluid is fine.
