This kit will get you the extra parts you need to change out the weak 4L70e in your Trailblazer for a much beefier 4L80e.

RWD Kit includes:
Crossmember - Bare or Optional Powdercoating
Harness
Yoke

AWD Kit includes:
Crossmember - Bare or Optional Powdercoating
Harness

Optional:
Crossmember Powdercoating Black or Red
TCI Flexplate
RWD Driveshaft
AWD Both Driveshafts (Fits 261 case only)
