Hi..I'm new here so I'm hoping this post is in the right place. I recently took my 2002 Impala LS to the dealership to have the catalytic converter replaced for the 3rd time in less than a year (yeah i know) and the dealership told me that my car was giving them the 1811 code. It's a transmission pressure control solenoid or something. I have put Seafoam in to try and buy some time. I was told by someone that getting the fluid and filter replaced my solve the whole problem. Is this true?? Also, can going a while before fixing this totally fry my trans? Any feedback would be greatly appreciated. Thanks.... (can't get my font out of this italic...lol)
