I have a 01 with 155k on it and 4th gear is gone. Found a junkyard tranny but he don't know if it's a HD or out of a non SC car. Has around 100k on it. My question is what can I read on the tag to see if it's a HD tranny? If it's not how can I covert it over. I obviously know from using the search function the diff and converter need swapped but I can't find any working links that show me how to. No one rebuilds these transmissions in my area anymore. Getting it tuned for the different ratio isn't an issue and I read something about the passenger axle shaft being different which isn't a big deal. Anyone have any useful info on this subject?
