I am a novice mechanic at best and I hate to be the bearer of possible bad news but our Impalas are notorious for bad head gaskets. Bad to the point that there is a lawsuit out there against GM for several thousand Impala owners over a similar situation.

I would have a friend who is a good mechanic check the upper and low head gaskets.

Is there any lawsuits for bad transmissions @ 72000k on a Impala?

I am sure that your intake gasket is at fault like thousand of other impala owners if your year is 2003 and lower. The 2004 models were corrected from this problem of dexcool eating the plastic intake manifold gasket. I had a 2003 impala with 160,000 kilometers a bit over 100,000 milles. I had no isue with my gasket. It was only a matter of time but the real issue came from my transmission with major problems concerning the lazy solenoids that were giving hesitations at start up etc . I got rid of this car to upgrade for a 2009 uplander lt. So far the van has 16,000 kilometers and not a single issue of troubles.

Intake gasket is your problem

how hard is it to replace this gasket... and if I have one which had the gaskets replaced 4 years ago will it to still have the potential to a dex cool problem again

Dex Cool was never the problem. Its just bad gaskets. Ive never done it myself, but its not horribly bad

I have had your same problems!! and so has my buddy with the 2003 impala upstate as well. Cost $575 to replace the gasket 3 weeks ago, and guess what wnt out this week? THE TRANNY! Anyone have a link to that chevy impala tranny lawsuit? I think I and the rest of us have grounds for a claim. BTW, anyone know if the 4T65E transmission from another car can be used? Thank you!

Gosh anyone have information on this lawsuit. I cannot afford to pay for a transmission on a car I still owe on. This is crazy!!!!!!!!!!

Intake leak is right. Replace the intake at the same time. Trust me. Or it will leak again.
