Fast & Easy Core Return
The Hard Hat 4L80E retains its factory shift pattern and is a great option for stock vehicles that still want a stronger, longer lasting transmission than a regular OEM replacement. The Hard Hat transmissions have a normal shift pattern for ease of driving, but are much more durable than a factory OEM replacement. This model has the option for gas or diesel applications.
The 4L80E is compatible with Chevy style GM engines, it requires a transmission controller, the controller may be factory-integrated with the PCM as on 1991-1999 TBI & Gen II engines, with the 1999-2007 Gen III engines, or the 2007+ Gen IV engines. Or, the controller can be an external GM or aftermarket unit designed for earlier engines.
Gen IV style 4L80's do not mix and match well, as they have an integrated Transmission Control Module and require a CAN bus network signal to a properly matched engine.
