If it's an automatic trans--how often was it serviced? The auto trans maybe the weakest link in the whole drivetrain, or it could last forever, depends on how it was driven.
What is up with the #4 Injector? I have looked around on the site and I don't find any posts about it. Can you give me more information about it?
