O.K. it appears that I have barbecued the VCM, (99 Suburban). I have checked and rechecked the trans codes and all the code work charts keep coming up replace the VCM. I am ready to bite the bullet and get one but am not sure where to get it. There are numerous companies on the internet that sell rebuilt units for vastly varying prices. I don't want to over spend but don't want to go for the "bargain" and get something that either does not work or does not last. Any suggestions out there?
