What year 6.0 Engines will fit - 2000 2500HD

1994, Thanks for clearing that up!

Any 6.0L that does not have variable cam timing or AFM should be O.K..

300,000+ miles kind of makes you wonder what's the point of a diesel anymore!

No 6.0L has AFM does it? I haven't seen one, but I admit I have not seen every 6L made. Not really sure why VVT would be an issue in regards to a swap. Use a ECM that pertains to the engine.

The L76 in the Vortec Max trucks as well as the Hybrid trucks 6 liters all have afm. You aren't easily just dropping a gen 4 engine in a gen 3 truck. .. it's not plug and play nor even worth the trouble. I know one person who actually swapped the gen 4 controller into a gmt800. .. and ended up taking a gen 4 truck bcm as well as wiring and even the hvac controls from the newer truck as absolutely nothing worked.

OP just stick with gen 3 and you are fine.

99 and 2000 just had iron heads. 02-06 had aluminum heads

2001 also has aluminum heads...

Typo. As you see in the post that 02-06 says aluminum. 2001 was not mentioned at all.

I have 2003 2500HD, lost engine due to hole in oil pan. Bought a 2000 6.0 with 109,000 with cast heads. Is it worth hassle to switch aluminum heads over to other engine? Do I have to switch intake Mani also?

Will a transmission (4L80) out of a 2003 gmc 3500

Work in a 2009 gmc 2500HD

Both had 6.0 engines

No.

The 2009 trucks run a 6L90e transmission. The 4L80e was never offered in those. Only another 6 speed transmission or rebuilding the current one will be a plug and play aside from possible programming needed. For sure a different transmission will be to be programmed with the correct VIN/OS to match the calibrations. Getting the original unit rebuilt would only need the transmission relearning features reset. A transmission shop would reset the learning stuff anyone with a rebuild.
