In the past 100 years, technology has transcended any imaginable science fiction ideas that may have existed in the minds of men. Every modern product had to start somewhere before being improved upon in a consistent manner in order to sustain itself in the marketplace. Based on the C4, C5, and light duty applications of the FMX, the Ford AOD (automatic overdrive) came into existence to use less fuel while offering durability. Its beginning years were a little rough, but with the modifications that Gearstar Performance Transmissions can perform on this custom-built Ford high-performance automatic transmission, motorheads will find the utmost of power. Anyone from Detroit, Michigan, to Kannapolis, North Carolina, looking for the perfect complement to the power of their ‘34 Ford street rod with a 351W engine putting out 500 horsepower can trust the expert technicians at this hot rod transmission company. Not only does Gearstar custom build each Ford performance transmission for each vehicle’s exact modifications from Chicago, Illinois, to Akron, Ohio, but also for GM and Mopar with one skilled technician that follows it through to perfection.
