Wondering if anyone knows what this might be. Found this rubber cover on the transmission as I was snooping under the hood today. Thinking that it might be a pre installation port cover from the ECM which is right over the trans, possibly left there by workers....anybody know? thanks, Mike
That's probably the case. It has a part number that I Googled and it referred me to an inverter on a Buick Skylark ?? looking at one I saw no connection. I'll check a few more locations on the vehicle just to make sure that road salt isn't poring into some port.
