2000 6.0 to 2006 4l65e. Can’t mate up
So my H2 engine was having problems. I found a 2000 6.0 with low miles. Did my research found I needed a 6.0 with the 8th digit U. Got the engine In and started up no issues using the original transmission (my h2 is a 2005). BUT. IT wouldn’t go into any gear. The common census was when putting the engine in we messed up the oil pump and it had high mileage. So went and bought a newer tranny with lower miles. Brought it home but they won’t mate up. After several attempts we found this
Different from their Chevy predecessors, most of the Gen III engines (see chart, below) had a shorter crank flange, offset of about 4/10" closer to the block. This is not an issue when working with original-configuration GM powertrains, but must be addressed when mixing different iterations of GM transmissions
so with that being said is there anyway to get an engine from a 2000 6.0 to mate up with a 2006 4l65e?

MOVED from the Drivetrain Area where it says: "This section is an archive of older posts, please post new questions in the specific model section. Thank you!"
You answered your own question. Don't mixed different generations of powertrains.
If Advance Adapters doesn't make an adapter, do not know where you could find one. Go to their website, create a login account, and search by vehicle profile.
Good luck.

Maybe this will help you found out exactly what you are working with and what you need to fix it. I think it’s just a spacer.
