Offroad Trailblazers and Envoys

TCCM part number?

G80, GU6, GT4, GT5, WTF? This section is for gearing and driveline stuff.

Im looking to order a TCCM off of ebay in the next week or so and I'm wondering if the part number is a big deal or if there is a specific one I need?

Old 2002 units to shun: 15074733

New one from 2003+: 12590220

Make sure you get one used from a TB or Envoy with a NP226 transfer case with LO range, not one of the lame AWD units from NP126 platform with no LO range.

Dorman also offers an unit (599-113) that I think needs no overpriced dealer flashing.

No. Only virgin new ones, or one from an AWD platform like the Rainier would to visit the dealer and bend over.

Really appreciate the help. Hopefully I can get this in soon so I can get the rig dirty.
