Is this true? Is the balancer different from an auto to a manual?
Not different from an auto to a manual, but different from a 7.3 IDIT to a 7.3 N/A. I did lots of research on the 7.3 IDIT engine. It was only made for about a year, and then as an option engine.
Trust me, I know, I have experience.
I have had an E4OD out, changed the fiexplate, and put it back in, only to take back it out, and put the old flex plate back in. The engine shook bad enough to shake the whole truck.
BTS, Brian's Truck Shop is the only one that I know of that has the correct flex plates for the 7.3 IDIT to the E4OD. He has them made.
I learned about him on Oil Burners, I think, but I don't remember who to give credit to.
