Well........I picked up a 2006 aluminum L33 5.3L and 2005 2WD 4L60E yesterday. No turning back now. Gonna have to change the thread title now!
I got the VIN numbers from the vehicles they came out of. Ran the VIN's and they are indeed out of what I was told. The engine came out of a 06 Chevy ext cab 4X4 and the trany came out of an 05 2WD 5.3 Chevy crew cab.
Now this is where I need some clarification. The trany has an extra bolt hole where there is no threaded hole on the engine block. Is this an issue or did I get the wrong trany?
Does the PCM control the trany or did I forget to get a controller that goes with the trany?
Here's a few pictures.
