Chevy Performance - Hughes 4L80E Automatic Overdrive Transmission And Kits

Chevy Performance - HUGHES PERFORMANCE 4L80E TRANSMISSION AND KITS

The 4L80E transmission is original equipment for all heavy-duty GM truck applications. It’s GM’s latest offspring of the TH400 trans, and we all know how tough that piece is. With GM’s latest refinements and electronic controls, the 4L80E is stronger and much smarter than its TH400 predecessor, even with its Fourth-gear overdrive. When modified for all-out performance, the way the Hughes Performance Street/Strip 4L80E is, the 4L80E stands alone as the ultimate setup for extreme-performance.

4L80E Automatic Overdrive Kit And Some Options

Mike Henderson, 1967 Camaro, Hughes Performance Powerglide and Converter

4L80E - The complete Automatic Overdrive with no-sweat installation that can be used for all makes and models, with adapter.

     Automatic overdrive transmissions have become “the”setup for the future. This technology allows the use of steep gears for performance while not interfering with highway cruising and fuel mileage, thanks to the big rpm reduction that their Fourth gear overdrive provides.
     Does your engine produce high horsepower and torque numbers due to nitrous or a supercharger, and it’s exceeding the capabilities of the 200-4R or the 700-R4? Maybe it’s time to consider the GM 4L80E electronically controlled four-speed transmission.
     In street applications, the fuel savings alone are probably worth the price of an overdrive, especially if you’re running a big-block. And the wear and tear on your engine is reduced, since the overdrive will have you cruising at about 1,000 rpm less on the highway.
     The 4L80E transmission is original equipment for all heavy-duty GM truck applications. It’s GM’s latest offspring of the TH400 trans, and we all know how tough that piece is. With GM’s latest refinements and electronic controls, the 4L80E is stronger and much smarter than its TH400 predecessor, even with its Fourth-gear overdrive. When modified for all-out performance, the way the Hughes Performance Street/Strip 4L80E is, the 4L80E stands alone as the ultimate setup for extreme-performance.
     And because we can program this electronically controlled transmission to suit your specific needs, you can have hard-hitting drag-race-type shifting at full throttle but also reliable part-throttle street manners GM has designed into the unit. Now more then ever before, is the era you can build your hot rod, custom car or truck, or maybe that street machine you’ve always wanted, and have a state-of-the-art transmission assembly. Hughes Performance’s continued research and development allows you to have the best, most reliable and longest lasting transmission and converter kit with the latest technology available on the market today! Call our experts today and understand why Hughes should be your only source for automatic transmissions, torque converters, and related components. Hughes really does care!
     The thought of installing an electronically controlled transmission might be intimidating for some. But wait a minute. Installing one of the transmissions with the electronic hardware really is simple. Hughes furnishes all the optional necessary hardware to make this installation a snap, including a foolproof stand-alone computer. You can even utilize the OE column shifter, or, for floor-mounted applications, the Performance’s Mega Shifter can be installed for 4-on-the-floor. Hughes now ships the programmer with the optional control unit to facilitate program changes quickly.

Note: The Transmission TCM Computer Kit 25-100, the Speedometer Controller for installing 4L80E in older vehicles with mechanical speedometers 25-150, etc., are not included with these kits. They have to be purchased separately. This, along with rewording their description above some, is to clarify the somewhat misleading description of these kits provided by Hughes in their catalog. These kits only include what is listed below under “Transmission Assemblies”.

Note¹: All Stall speeds are approximate ratings for fresh big-block engines, small-block engines will vary 300 to 500 RPM’s lower. All stall ratios will vary according to your specific application. Specialty custom units for tractor pull, monster truck, nitrous or super charged applications, will result in minor additional charges due to extra time and materials required. Note²: Due to computer controlled electronics, Non-Lock-up converters are not recommended for these applications.
