Gear Vendors Overdrive Installation
Gear Vendors' Overdrive Provides Cruising Efficiency For Classic Mustangs
It's getting easier than ever to get classic looks and late-model performance all rolled into one sensational ride. This technology is available via modern fuel injection, performance brakes and suspension, sound deadening, sound systems, roller tappet camshafts, improved lighting, power windows, larger wheels, and speed-rated tires. Overdrive is another popular upgrade with a late-model AOD automatic or a five/six-speed manual. But you can also upgrade to a Gear Vendors overdrive for your C4/C6 automatic or four-speed Top Loader transmission.
If you're fond of the sound of First gear in an old close-ratio Top Loader or that soft whine of the First gear planetaries in a classic C4 Cruise-O-Matic, Gear Vendors' overdrive unit is the perfect solution for your vintage Mustang. Originally conceived to help motor homes cruise more efficiently, it wasn't long before Gear Vendors applied their approach to classic muscle cars and weekend race cars. Gear Vendors now has an overdrive for virtually every vintage Ford transmission, including C4, C6, and Top Loader. What's more, this rugged overdrive unit has withstood as much as 1,850 hp in NHRA competition, so it will definitely stand up to the rigors of your classic Ford V-8 in street and strip use.
The Gear Vendors overdrive isn't just a shift into final drive, then overdrive, although you can do that with it. You can also shift in and out of overdrive on the fly in gears one, two, three, or four in a practice called gear splitting. This happens via sophisticated electronics that enable you to engage overdrive manually or automatically based on vehicle speed.
The Gear Vendors overdrive works like an automatic transmission, which makes it hydraulic in function with a cone-style clutch pack. Set your Mustang in motion and your transmission's output shaft turns the overdrive's pump. If you're in Autodrive mode, upshift into overdrive happens at approximately 45 mph. In manual mode, overdrive happens whenever you desire.
