    I have this same problem, my 2004 avalanche had a big clunking noise and stopped working in drive. I can get it to move in 1st gear and 2nd gear but makes a hissing noise in 2nd gear.

    transmission stays in 2nd or 3rd gear when you come to a stop the trans is not slipping its just not down shifting it can be manually shifted with the selector this only happens every other time i start the truck

    My transmission just went out today! I was pulling out of a parking lot and the transmission made a winding noise and wouldnt move the truck and then popped into gear long enough to get me about a half mile before quiting totally. Now that I think of it, the transmission has alway seemed not right.

    My 2004 Avalanche started delaying in second gear but would eventually go to third. I could not get it to go faster than about 55 but that hurt to hear the strain. What might this be

Are you getting the check engine light? If so the electronics may have gone out. You may not need a rebuild but you won't know till you pull the oil pan on the transmission and inspect the contents. You may also have lost the neutral safety switch. It is mounted on the drivers side of the transmission. Check those out first and let me know what codes you get.
For Ponchoboy; the clunking and hissing you hear are teminal root causes. Drop the oil pan and if it has a lot of filings and metal it is time for a rebuild.

I have a 98 chevy silverado. My transmission only has 2nd,3rd and reverse if you manually put it into 1st it still has 2nd gear in 1st&2nd gear and 3rd gear works in 3rd and drive only. Nothing higher

Remove trans pan and inspect shift solenoids. These are prone to come apart and visual inspection often finds the problem. Replacement units include a bracket to keep this from happening again.

2007 Chevy Avalanche 3rd and 4th gear are not working

From what you are describing, it is possible either the 3-4 actuator is no longer playing with the 3rd & 4th clutch packs, only way to know for certain is to hook up the good ol' pressure gauge to trans. system, yeah, you think the Chevrolet dealer should know this right?

Sell it now if you can!

Try cleaning the MAF sensor. Computer uses that info to determine pump pressure. If that doesn't work, you're looking at a new tranny

I change the oil and filter and now only 1st an 2 change but not the 3

You transmission may actually be shifting in 2nd and 3rd gear. If that is the case, ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM. Have the Avalanche scanned at a transmission shop for DTC codes to confirm the Shift A solenoid needs to be addressed.

Call around first, most transmission shop will test drive the vehicle with a Tech2 scanner to confirm this issue. If they tell you that you need a new transmission, go to another place.

Thank you for using Fixya and keep us posted.

2004 Avalanche will not move in drive. Only revs.

Take your truck to the dealer and describe the problem exactly as you have here. You have an internal transmission problem...and its probably going to be expensive. You can ignore the problem but are chancing further failure as problems generally don't go away or get better. Broken pieces may be floating around in your transmission oil and could create a more expensive repair.

2005 Chevy Avalanche Transmission Problem

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.
