I've got a 2009 Chevy Express (Van) 3500, With a 6.6 Duramax motor, but a 4L80E behind it, looking to try and find a replacement, but I don't want to buy something unless it's going to work. Can I just swap any 4l80e in there newer than 2004 or so? I'm lost guys any help is greatly appreciated.

Rock auto tells me it's this Trans. code 4L80-E; TAG: 8MKP, 9MKP, 8MLP, 9MLP, I don't even know what those tag numbers mean.
 
You have a 4l85e, not a 4l80e. It was used behind the duramax in vans from 06-09, and the 8.1l in suburbans, yukon xl, and avalanche(but they were mostly 4x4's). The 4l80e from 97+ can be bolted up to it, but I would stick with the 4l85e as it is better designed to handle the DURAMAX's torque.
