4L60E to 4L80E Conversion Tuning

PATC has solutions for all of your transmission needs. When converting from a 4L60E to a 4L80E transmission it is necessary to perform a segment ID swap on the pcm for proper shift strategies. PATC can perform this swap for you using HP tuners software by email or with you shipping us your pcm. Please call Blake for pricing @ 1-888-201-2066. Fill in the shopping cart to the right and we will call you for details.

4L80E Custom Tuning

Why is tuning so important for my late model transmission?

With today’s technological advances transmissions are just as complicated as modern fuel injection engine management systems. These super computers can make adjustments to your transmission in just millionths of a second. The days of simply making a few mechanical adjustments and improving shift quality and feel are over with. We now must take into consideration shifting strategies within the pcm or tcm to compensate for the mechanical improvements we have provided within the transmission. Below you will see a good example:

  Above we have a stock table from a 4L60E transmission. This is the desired shift time table. If you noticed this table is based upon ft lbs. of torque. Look at the top row and go to 240 ft. lbs of torque, you will see that the computer is looking for a .450 second shift in that cell. This is ½ second shift from 1^st - 2^nd. If we were to simply install a servo and boost valve in this transmission, the computer would see that the transmission is shifting too quickly. The adaptive strategies of the transmission would then increase the voltage to the force motor, trying to achieve a softer, longer shift. This would be a complete opposite of what we are trying to achieve. In high horse power or heavy towing this long delayed shift would result in added wear to the components in the transmission. The longer the shift (smoother) the more slippage that must occur. Automobile manufactures are faced with 2 issues, a dual edged sword if you will. While they are always searching for improved ways to increase the life of the transmission, they must also consider the NVH factor. NVH stands for Noise Vibration Harshness.

  Next below you will find an example of another 4L60E table which involves Torque Management. This is a strategy to control the the amount of power the transmission sees in between shifts. Giving you longer, less desirable shifts. In our tuning we do delete some if not all of this according to your needs and the build you are getting.  While the most efficient would involve no slip, improve acceleration, and reduce transmission temperature. This would also cause a harsh and abrasive shift that the majority of consumers would find unrefined. Our tuning can provide you with the best of both worlds. When combined with our components we can provide the perfect set-up regardless of your needs.

No computer needed. On the fly adjustability. #4L80ESimpleShift. Don't have a laptop? Don't like computers? Want instant on the fly adjustability? Need an overdrive solution for that new LS conversion on your beast? Here you go, the Simple Shift transmission controller is your solution. This stand alone transmission controller is capable of operating your 4L80/85E electronically controlled transmission without the need for any complicated computer tuning. Shift speed, shift firmness, and converter lockup are all adjustable with just a simple twist of the dial on this controller. The settings offer 2 different logic settings both for part throttle and wide open throttle. When clicking on the thumbnails pictured left you will see this indicated as low / high which is relative to throttle angle. This controller comes complete with a factory grade wiring harness and all factory connecters. This is one of the easiest controller to install on the market today. The wiring harness you see pictured to left has all connectors clearly labeled for a hassle free installation. Using a separate TPS which stands for "Throttle Position Sensor", is not needed on this controller with any fuel injected vehicle. The wiring harness already has the leads for the TPS sensor that would currently be used on the vehicle. If this is going on a carbureted vehicle you would want to add the TCM-6000 TPS kit listed below. The Simple Shift is the perfect solution if you simply want to use an overdrive electronic transmission in your project car, but don't want to worry about the controller.

GSM Push Button Shifter This push button shifter is a beautiful piece of art. This is ideal in instances where maybe you have an old school restoration with a bench seat and a 3-speed column shifter, and no room for a floor shifter on that new 4 speed transmission. The GSM Push Button Shifter is an electronically controlled shifter that offers precise, split-second shifting capability with the simple push of a button. It's slim touch pad control module and compact, sealed actuator give you virtually unlimited mounting options for tight spaces or grueling environments. The GSM replaces the shift lever for nearly any Automatic Transmission. This New state of the art control module can be surface or flush mounted and is small enough to fit in consoles, dashes, door panels, or even armrest. Each button is recessed to avoid inadvertent touches and brightly backlit for darker environments. An easy to read display shows exactly what gear you are in. The standard control modules utilize a PRND configuration along with a "+" and "-" buttons for easy tap up/tap down feature. Custom Modules are also available. The compact actuator box can be mounted next to or near the transmission and connects to the transmission using a flexible shift cable further expanding the mounting envelope. Wiring is very simple requiring only power, ground brake input and vehicle speed to operate safely and precisely.
