SOURCE: chevy avalanche transmission problems

Hello;
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.
Hope this helps; Rate me highly;

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!

2003 Chevy Avalanche won't start (incorrect gear indicator)


PRNDL Display
The instrument panel cluster (IPC) displays the selected gear position as determined by the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the gear position. The PRNDL display blanks if:
• The PCM detects a malfunction in the transmission range switch circuit.
• The IPC receives a class 2 message indicating the park position and the column park switch indicates a position other than park, open input.
• The IPC detects a loss of class 2 communications with the PCM.

Could be the transmission range sensor . Testing would need to be done , hooking up a scan tool ! Doing electrical testing etc...

My chevy avalanche aircon blower will not start on 1st to 4th only works on 5th speed. Chevy Avalanche 2003 model with 5.3 L


Sounds like a blower motor resistor. Not an expensive part, fairly easy for a mechanic to change. Located usually behind the glove box door.

The engine light comes on and the reduced power is activated ,there sensors were tripped all to do with the throttle . the auto shop ended up replacing the throttle body and the problem just happend again...


I'd bring it back to the shop that put in the throttle body and have them check to see if the replacement was defective or failed. If not, you may have a bad throttle position sensor [part of the gas pedal] I'm assuming it worked fine for a while after the repairs with no problems then suddenly started acting up again. I've replaced a bunch of throttle bodies but only one position sensor so far. There's always the chance that there's a bad wire somplace or some other more exotic problem but I'll bet you'll find it at either the sensor or throttle body. Good luck, hope this helps!

On my 2004 chevy avalanche just died one day when you star it starts but if you step on gas it losses spudders and dies


Oh the list of things it could be is pretty long.
Lets start with hmm bad TPS or plugged fuel filter? or underperforming fuel pump?

Lets see if it was really sudden id start with checking the TPS among other things.
If it happened kinda slow then id start with the fuel filter.
Poor voltage to the ignition system can sometimes have that effect too.

2003 chevy avalanche 1500 4wd stalls when not on the gas


The meter will jump when the engine isn't running proper. It sounds like a fuel pump issue to be honest.
