Hi, This is a bit of a strange situation. I didn't find anything else on this by searching. My vehicle is a 2006 GMC Envoy SLT. It's has about 230k on everything except the engine and alternator and starter and battery. To make a long story short, I got in the car and it would just barely turn over very slowly and not start. After two tries it stopped turning over. I had this happen to this car a few years ago and it was the starter. Thought I had a dying battery but the starter was failing. Replacing it fixed the problem. So skip ahead to 2 days ago, showing the same symptoms, I replaced the starter, I have a fully charged Optima battery and no change, the same thing, slow crank over once or twice and now it won't crank over at all and I hear something down by the starter/trans that sounds like it's frozen or a slight tapping and i thought I had heard a squeak the few times it would barely crank over with a fresh strong battery. Is it possible that a bad Torque converter, could be frozen and preventing me from starting the vehicle? I tried cranking it in Neutral, no change. The car is stuck in a parking lot, fairly far from home with no AAA and very little money so I'm really in a bind with it. A transmission replacement is probably out of the question but I might be able to scrape up enough cash to replace the TC. I just don't know how to narrow it down and pinpoint if that's the cause. Thank You very much for your help.
