The guys from Detroit Muscle rebuild the popular GM HydraMatic 700R4, a 4-speed automatic transmission with a 30% overdrive in 4th gear.
The development of this transmission was primarily targeted to improve fuel economy, and this was accomplished by a number of modifications, not the least of which was the 30% overdrive capability.
The 700R4 was used widely on both truck platforms and rear-wheel drive car platforms. Some of the popular trucks it was used in were the Chevrolet Blazer and Suburban and the Oldsmobile 350 diesel. This transmission was also used in the Chevrolet Camaro, Corvette, Impala, and many others.
The guys offer tips and tricks on how to rebuild, upgrade and bulletproof a GM 700R4 automatic transmission. They also take a brief side-trip to the Tri-Five Nationals In Bowling Green, KY in this episode.
