OEM Updated 10R80 Internal Wiring Harness Assembly:
Notorious for breaking wires and electrical codes, the internal wiring harness assembly and 4 speed sensors are often not safe to reuse during a rebuild. They are also a smart update one can perform with our popular 10R80 valve body upgrades. These parts are notoriously difficult to access, but Next Gen Drivetrain keeps them in stock at almost all times for both our own builds and yours. Need extra help?
