Bring to tranny shop or repair shop, have it scanned for trouble codes, many electrical parts and solonoids in those trannys, possible it may just be a shift solonoid bad or needs adjustment, much cheaper than replacing tranny. good luck!

Yes, you are correct. i would change the filter as well. check the torque converter for stress.

SOURCE: My chevy aveo won't go into gear. The gear shift

Most likely the shifter cable broke or became disconnected. Have someone shift the car (engine off, parking brake on) while someone else watches the transmisssion linkage to see if it moves. If it does move there is an internal transmission problem if it doesn't it is just a problem with the cable.

ur computer probably wont show anything ur tranny problem can be anything fron needing a filter changed to vacuum problem to torque converter check the fluid for level if low fill up- before filling look and smell fluid it should be reddish in color not brownish [fluid burnt]if it smells burnt- need trans service can be just a filter and flush ,bad sensor-actuator or rebuild

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!

My 2003 Chevy Avalanche is having trouble shifting from 2 wheel to 4 wheel or to Auto Drive. Every time I start the truck it is in the 4 x4 mode regardless of where it was left when last turned off. I live...


Just a question. Does the truck do this after the truck is warmed up. If not this is a temp. issue and can be a few items. Generally this is an electric switch issue. Remove the fuse from the system when you shut it off for the night and see if it still jumps to 4x4 mode.

It means just that, the transmission is overheating, don't continue drive it you will ruin the trany for sure. Get it to a trany shop it's most likely a simple fix.

2003 Avalanch fuel gage


You have a problem with the stepper motor gauge that Chevy used in the 02-06? Avalanche. All the gauges use the same stepper motor. They just go wonky and do all kinds of weird things. I have replaced two on mine already and two more are now acting up. There is a guy selling the motors and the repair for this problem on E-bay.
