It contains springs, valves, and many fluid passages that are critical to the proper operation of the transmission. Please refer to the core return instructions included with the part or contact customer service for more details. We offer two different transbrakes. The torque converter can be locked up in 2nd, 3rd, and 4th forward ranges if necessary. Fits 1996 and up models.
We will also offer tech support to help with the install. There are a lot of options in automatic transmission control. Customer responsible for return shipping on core items. It does not include the converter cut and clean, or hard parts. Please refer to the core return instructions included with the part or contact customer service for more details. We also offer Full Manual valve bodies or stand alone transmission controllers to run them.
This conversion box effectively maxes out the transmission line pressure so that each gear change applies full hydraulic pressure regardless of load on the engine. You can receive a refund by returning a suitable old core. This pushed us to look for a less expensive alternative. The 4L80E utilizes a lock-up torque converter which allows you to have the best of both worlds… high stall speed and maximum torque multiplication to maximize the performance potential of your combination, and lock-up function via an internal clutch which virtually eliminates all heat build-up in the converter at cruising speeds while providing even more efficiency in addition to the efficiency increases already provided by overdrive. The consistency and durability you will receive with the Hughes valve body line, is second to none.
Includes complete valve body with new internal wiring harness, all new solenoids, and new pressure manifold. Offer excludes truck freight and oversize fees. Includes complete valve body with new internal wiring harness, all new solenoids, and new pressure manifold. Coming soon is our very own Hughes Performance electronic control unit. Stage 4 builds are mainly for heavy vehicles, diesel, or large uses of N2O. We specialize in building the 4L80E for retrofit applications.
Paddle shifters are readily available and can easily be installed with either controller option. The valve body of the transmission, or control valve, is the central nerve system that tells the transmission what to do, at what time. Description Our 4L80e and 4L85E transmissions are one of the strongest in the world. Our premium controller is manufactured by Compushift and includes a simple hand-held calibration module that allows you to fine tune shift firmness, shift timing, lock-up function, and select between automatic and full manual operating modes. It is a very quick acting transbrake.
This kit will only work with production valve bodies that have not been previously modified. All 4L80Es also include a new boost valve assembly, new shift solenoids, manifold pressure switch, internal wiring, as applicable. Zero Gravity Performance is a company with over 30 years experience working in the automotive performance market. The Compushift module also provides a real-time display of transmission function data including range, fluid temperature, line pressure, etc. Valid on orders shipped in the contiguous United States. Transmission brake can be applied in the D3 range and will shift automatically, or can be placed in the D1 range giving the driver full control over the wide open throttle shift points. MarcThanks for the info Marc.
If anyone is interested I can get you product. We offer numerous services to assist you in getting the best performance from you vehicle. This kit comes with Gaskets, Separator Plate, Solenoid plugs and Instructions. All 4L80E transmissions have the old style flywheel. The late model type are built from 1997 to 2001 cores are known to be the best.
Redesigned oil circuitry provides super positive gear changes, increased torque capacity and instant transmission brake release for the ultimate in efficiency, performance, and durability. All late-model overdrive automatics are now microprocessor managed, which makes converting one of these transmissions more expensive, since it requires a separate, stand-alone electronic controller. Some 2 inch diameter pipe was cut to length and used as spacers for the fabricated crossmember to give the proper height under the rear of the transmission. We are located in Mesa Arizona and have been building high performance transmissions for over 25 years. Check out the new aluminum valve bodies that offer better heat dissipation over cast iron. It has some special tuning considerations for use with a controller in an automatic shift situation. That is why they say if your running stock gears it might be better to have it run as a 5 speed because the 3 to 4 gear split is so small.
It has withstood 1400 hp dragster, endured 850 hp offroad trophy trucks running in the Baja 1000. I know they talk about gear sets, but I don't think they are adding gear sets, just changing the ones that are already in the trany to a different ratio to get a better split between gears. All components are provided installed on your transmission when you order the mechanical speedo option on your Hughes Performance 4L80E. The 1997 up 4L80E transmission can be used on the new Chevy 572 cubic inch motor, because both have 7 bell housing bolts. Full manual valve bodies are used for high performance applications where you don't need a transbrake to launch. Fits 1991 thru 1995 models. Both transbrake options feature a forward shift pattern, and still retain the lock-up torque converter function as well.
