Hi,

thanks so far.

So the best way would be to stop at a Transmission Shop or Buick Dealer and let them check out what exactly the Problem is, right.

After that I can buy the right parts and start taken my car appart to change, lets say one stupid solenoid which sits underneath the side-cover of the Transmission. Am I right.

Another question. Does anybody knows a software for ODB-Scanners.
I have three different ones all ODB2 compatible which I hook up to my Laptop. The software I have covers only german brands like Audi, BMW, VW and so on.

Thanks in advance
