Check out the engine and driveline portion of my webshots page. I believe that I have solved the problem. All I need to do now is get the gear mesh pattern right and I don't know what to think of mine. That's on the webshots page too. I posted a thread about this on oldgmctrucks forums, but I can't access it right now for some reason. It is under the "active questions" section of the project truck forum if anyone wants to read it.
