2016-2020 Buick Envision 2.0T Automatic Transmission Radiator

Do I need to flush the transmission before installing this?

Flushing is not required for installation, but if your transmission fluid is dark or burnt-smelling, a service beforehand is smart practice. Check your owner's manual for recommended service intervals.

Will this radiator work with my stock cooling system, or do I need upgrades?

This radiator is engineered to work within your factory cooling setup. No additional upgrades are necessary unless you're running significantly higher fluid temperatures from modifications or extreme driving conditions.

What tools do I need to swap this out?

Basic hand tools and a drain pan for transmission fluid. The assembly mounts at factory points, so no special adapters or fabrication is required. Refer to your service manual for torque specs and drain/fill procedures.
