2006 Impala SS Transmision FAILED!

I took it to the dealer on Monday and of course they could not recreate the problem. They said that based on my description it was either a solenoid in the trasmission or some sensor, but without the car exhibiting the symptoms for the mechanic they would not do anything. They told me that no damage is currently happening to the transmission and they would be more than happy to fix the problem if it starts happening more. They suggested I drive it until the problem gets worse...

I find it hard to believe that the loud clunking sound I sometimes get when the transmission engages isn't causing any damage. It certainly sounds bad enough...

I would think they could look back with their scan tool, at the datastream, if anything went funky it should be there in the history/pending codes/datastream freezeframes.

I feel your pain. I have an '08 SS and today out of the blue without warning it was like the transmission didn't exist. Would not move no matter the gear selection. Killed the engine, restarted it 2 minutes later and was a able to move 30' before the tranny went MIA again, had to get it home doing this for 5 miles. Any suggestions?

Investigate to see if the transmission selector switch or the connector is loose, damaged or corroded. Have had some cars do this and it was a bad switch position sensor.

Funny you mention that, I told my wife too bad I couldn't check the linkage on it since their electrical instead of mechanical now. I'm too old school for my own good, give me a '70s Hot Rod anyday! I will check on the connector after work today, thanks for the guidance.

I'm also apart of this impala transmission fiasco..tranny is dead..out of warranty and 2600 bucks to fix it.best part is..I had it in a year ago to check the transmission and was told nothing was wrong..no codes.i even spent the money on a flush as well..I will never again buy a government motors vehicle..mine would have been paid off this upcoming May..something needs to be done..There are what..A few hundred people with the exact same issue?? GM is failing again..someone from their customer service needs to contact me asap

your issue is very common when these GM transmissions are flushed !!!!!!!!!

now my question is what fluid did they use III or VI DEXRON ???????????

Who did this flush ? was pan removed ? filter replaced ?

If this flushing was not done properly I would sue the repair shop that did this damage to your transmission.
