Which Transmission Line on 2004 Chevy Trailblazer is Return Line for Installing Transmission Cooler
Published 09/11/2018 >
Question:
Does anyone know off-hand what side is the COLD line on the trailblazers transmission for this tranny radiator? I think its the driver side, but the hanes manual does not specify.

We actually had the chance to install the Derale transmission cooler part # D13503 that you referenced on a 2004 Chevy Trailblazer just like yours. We found the return line from the factory cooler to be the one on the driver side. Fast forward to the 2:00 mark of the attached video to see this portion of the install.
