Does the harness you have now, show a section for a TCM controller, or does it just have a Range (PRNDL) plug and the main trans plug?

Do you have any of the DBW stuff from the donor, or is ALL that missing?

I'll check but I don't have any of the dbw stuff there's a package deal at current performance that includes everything needed but it is pricey. This is not an area I want to skimp on though as I really don't want to fight any gremlins with wiring down the road, or atleast minimize the possibility

In 2007 they changed the truck body style and the new ones got GenIV engines. They also made some of the old body style with the GenIII engines and called them Silverado Classics but ive only ever seen them in 1/2 tons, so you probably have the newer one. Post up a pic of what you have, they're pretty easy to tell apart.

No production GMT-900 pick-ups had a 4L80E, They switched to the 6L90E in 3/4 & 1 tons, The 1/2 tons still had the 4L60E for a couple years.

GM sold 2007 Silverado Classics in 3/4 & 1 ton versions.

And don't forget my favorite, FLEET PURCHASE! Anything in a commercial chassis or from a fleet purchase is usually on the classic setup (vans and commercial trucks have been 2-3 years removed in some cases).

definitely a 6.0 4l80e. i was told it came out of the newer body style in 2007

That's a gen 3 engine. It has a drive-by-cable throttle body, return fuel rail, and mechanical fan. It's probably not a 2007. More like 2003 (or earlier).
