Hemmings 1981 Chevrolet Suburban "Big Green"

1981 Chevrolet Surburban Big Green TREMEC TR-4050 Silver Sport Transmissions

Hemmings Muscle Machines is on the "Road to Improvement" for a 3,500-mile journey in this 1981 Chevrolet Suburban they've dubbed "Big Green". They acquired this bare-bones, old park service vehicle to do a sweet experiment. Throughout the road trip, they will be stopping by different sponsors to modernize the truck and make it a more enjoyable drive. Of course, one of the first big changes was the transmission. They stopped by Silver Sport Transmissions for a TREMEC TR-4050 5-speed. The overdrive should help them save gas, quiet down the engine, and help them maintain the 70 mph speed limit down I-40 to their next stop, Edelbrock USA for an EFI. When everything is finished, the plan is to auction the truck off through SEMA Cares which supports a variety of children's charities.

You can follow along on Hemming's Facebook and Instagram pages as well as Mike Musto's Instagram and Elana Scherr's Instagram pages as they travel for the next few weeks and we'll also update you when Hemmings posts the video series "Road to Improvement".
