#10A. Swap your 4L60E transmission to the much stronger 4L80E transmission with our new double strength case hardened output shaft and adapter kit. You can use the computer you have now on 1998 up models with the use of our #10X wiring harness. The transfer case you have now can be used as is and will be moved 1 3/4 to 3 1/2 inches to the rear. (WILL NOT FIT A 5 BOLT TRANSFER CASE)

#10B. This is a 3/4 inch spacer needed on some late model transfer cases to make the #10A adapter fit (Will require some slight fitting on 2007 6L Hummer H2 for sure). Needed on Borg Warner transfer cases used on Hummer 2 and Cadillac Escalade.

    #10X. Wiring harness to convert from a 4L60E transmission to a 4L80E transmission. 1998 up LS1 type only.

This harness takes a gray case connector, case side not wire side.

The computer must be re-programmed.

On 1997 back you will need a Compushift computer.

#10XL. Wiring harness to convert from a 4L70E transmission to a 4L80E transmission (Some 2006 On, 4L70E type with input speed sensor only)

This harness takes a black case connector, case side not wire side.

The computer must be re-programmed.

On 1997 back you will need a Compushift computer.

#LS1-700. Crankshaft spacer to install a 4L80E transmission on a LS1 type motor. Six longer flywheel bolts included. The LS1 flywheel is reused. The flywheel goes on first then the spacer. The torque converter bolt holes in your flywheel must be elongated to fit your non-LS1 torque converter bolt circle. On some late model Hummers as much as .160″ may need to be machined off of the front side for proper converter pilot shaft fit.

  #10C. Crossmember for the 4L60E to 4L80E transmission conversion, 2000 up Tahoe and some others. This custom made crossmember moves the transmission mount to the correct position for the 4WD Tahoe 4L60E to 4L80E conversion. Works with the #3XX deep cast aluminum pan that holds 3 3/4 extra quarts of fluid or any other pan. Cost $360.00. On some trucks the crossmember will slide to the rear. (We need the last 8 digits of your VIN number to insure you get the correct crossmember. Price may vary with model.)

There’s an extra charge for new speedometer parts. You must tell us if you need speedometer gears.#10D. Crossmember for the 4L60E to 4L80E transmission conversion, 2007 up Tahoe (NEW BODY STYLE) and some others. This custom made crossmember moves the transmission mount to the correct position for the 4WD Tahoe 4L60E to 4L80E conversion. Works with the #3XX deep cast aluminum pan that holds 3 3/4 extra quarts of fluid. This crossmember isn’t the same as #10C. (We need the last 8 digits of your VIN number to insure you get the correct crossmember. Price may vary with model.)

#10C-2WD. This crossmember was made for a 2WD 2003 5.3L half ton pickup 4L60E to 4L80E swap. This was a 500 horse power blower motor. The center section moves to the rear 6 1/4 inches. (We need the last 8 digits of your VIN number to insure you get the correct crossmember. Price may vary with model.)

#10H2. Hummer II Crossmember for the 4L60E to 4L80E transmission conversion.

#80D.. 4L80E Deep / Low pan for late model and Hummers (fits 1997 up plus earlier years), made for crossmember clearance. Comes complete with filter extension and bolts. Volume: 4.5 quarts over the stock pan.

#6080S. 4L60E to 4L80E conversion flexplate. This Flexplate works on all 98 up LS based engines with the exception of the LQ4 6.0. The LQ4 LS engine can be identified by the dished pistons. This new flexplate would be used when taking the 4L60E out and replacing it with the 4L80E. This flexplate is the perfect solution when doing the swap. Complete bolt on piece.

#10M. Extreme Duty Energy Suspension Polyurethane transmission mount for the 4L60E to 4L80E swap (4WD). Fits most GM full size 4WD.

#90. 4L80E SFI certified Locking Dipstick and filler tube with ultra-seal base to keep your leaks at bay.

#89. 4L80E dip stick with locking top

#19259119. 4L80E Cast Aluminum Dust Cover for a LS1 motor only (*see note). For 4WD and 2WD. Held on to the transmission with four bolts. Don’t buy this one unless you have a LS1 motor and a 4L80E with a 7 bolt bell housing bolt pattern.

* The early type non-LS1 4L80E dust cover is no longer made. If you have a 4L80E and a non-LS1 motor buy this dust cover plus the #52DC inspection plate below.

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.

#TCM-6000. This is the add-on component for the simple shift transmission controller when using a carburetor. This remote mount TPS adapter kit allows for the easy installation of the of the Simple Shift transmission controller in non-electronic applications where no throttle position sensor is present. Comes with adjustable kick-down cable, TPS sensor, TPS mount, TPS to kick-down adapter, weatherpack connector, pre-crimped wires, extra terminals, extra seals and mounting bolts.

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.
