Question about 2004 Chevrolet Avalanche

1 Answer

2004 Avalanche will not move in drive. Only revs.

2004 Avalanche will not move in drive. Only revs. It will drive if I start in 1st, then 2nd, then, 3rd, and finally drive. I heard a lound noise, when the problem first started, as we were making a left turn from a stop sign. It runs smoothly as long as it is manually shifted.

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.

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!

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.

Only reverse works. No foward gears.


No forward movement in OD or D, but L2, L1 and R work: Forward sprag is broken. R&R. Try not to run or drive the car or further damage could result.

Do you have manual 1st? If so, can you shift through the gears...i.e. manual 1st to manual 2nd then 'D' then 'OD'??? Only 1st and 2nd gears use the forward sprag unless the LO/Rev clutch is engaged...i.e. 1st and 2nd if in "drive". If you can shift threw the gears manually then, yes, your forward sprag broke.

If no manual 1st then your sprag is not what broke. Sounds like you blew up the rear planet. If you pull the pan and find chunks of iron and steel, then that is probably what happened. If you have reverse then it is not the pump. If the pump was bad you would have no line pressure and it would slip in rev. or no rev. Not the beef sun shell either because you have rev., a broken sun shell would cause no 2nd, 4th and rev. gears. Either way the trans needs to come out and torn down and it will be easily found what went. Good luck and thank you for using Fixya.
