[QUOTE="VH2K, post: 29572, member: 15488"] Hi, and thanks for the swift reply! No, I have not scanned it yet since I don't have a scantool, yet... I was planning on checking the connector, saw a few youtubes where oil leaked into this one and caused all sorts of issues. Let's say I don't care about the hard shifts and they are caused by some ECU-command because of a false/wrong signal, how damaging is this for the trans? Regards! [/QUOTE]
