Tried to search for the post about the difference between automatic crank and a manual crank but could not find it.
Is there a difference between the two and what about between an 03 and 06 crank?

No difference in crank shafts, that's why you didn't find anything. I've never heard of a difference in crank shafts on any engine. Talk about an engineering nightmare.

What are you trying to do? As questions about your project not small specifics. Lots of very knowledgeable guys who had done a lot of different projects.

Where the flywheel sides into the crank is different on the crank that was put into the engine during the rebuild. The shaft on the flywheel is about 2 1/8" and the place where it slides into is under 2".

the flywheel for the auto trans, and the flexplate for the manual trans should just bolt to the crankshaft. but they may be different cause the 03-04 have the 47re and the04.5-06 have the 48re... for things like this i call the dealers parts department and have them check to see if the two years, and the two trans have different part numbers.

It is because of the dual mass flywheel. I am going to use a regular flywheel and clutch.

 

[justadonor]

cranks will be exactly the same

They must have changed the crank in 06. That is the first year of the dual mass flywheel right?

No, the flywheel is for the manual and the auto's have a flexplate. Also only a few 03s had the 47RE. Most 03s had the 48re, and all later vehicals till 07.5 had the 48re. You pretty much had everything backward

To answer the question the cranks are the same for manuals and autos, no need to make a difference between them.

I don't know if by "any engine" you mean all manufacturers, but GM and Ford used to produce crankshafts that were intended to be mated to either automatics or manuals.
