TB/ENVY 4x4 Question

Discussion in 'Chevy Trailblazer Forum (GMC Envoy)' started by GM-Guy, Jun 4, 2012.

    Did they ever build the 360 platform with different drivetrain components

    Been looking for a 02-05 and running CompNine for the Build Sheets
    Some are listed with the NP8, which I believe is the 226 TC and some are not, but are being listed as 4WD
    Would these be AWD vs 4x4?
    or did they ever use Modules?
    Thanks

    The 360 came in 3 configurations:
    -2wd
    -4wd
    -Awd

    The Trailblazer/Envoy versions used the NVG226 TC, the Buick/Olds trucks used the NVG126 TC

    The 226 provides selectable 2wd/4wd/A4WD/Neutral, the 126 is only AWD.

    There is a third transfer case used in the SS AWD trucks, unlike the 226/126 TC, it uses a LSD configuration

    Thanks R-V
    Still confused why there are no TC RPO codes being listed though, maybe Build Sheet error or CompNines error?

    Probably no code, because there are no choices. There is a model number to distinguish the 2 wheel drives and the 4 wheel drives, when you order the 4x4, it comes with a package of parts, the T-case is just one of the many parts.

    If AWD was an option for the Trailblazer/Envoy trucks, there would be a RPO code for each T-case
