Holley EFI 6L80/6L90E Transmission Controller for Terminator X MAX!

Terminator X MAX users, unlock the full potential of your GM 6L80/6L90e 6-speed transmission with Holley EFI’s Transmission Controller. Using Terminator X MAX along with our Holley EFI Transmission Harness and handheld, you can control GM’s 6 Speed transmissions in addition to complete engine control. It features an easy to use interface that lets you raise and lower shift points, make changes for tire size and gear ratio, as well as read error codes from the transmission directly.
We also support 2nd shift pattern modes, such as Tow Haul or Sport mode. With the Terminator X V3 Software, you'll also have access to advanced features like shift mode, tap up/down shifting, torque management, and full parameter customization, allowing you to make your vehicle perform like never before.

its so damn nice for this too finally be out, hopefully one day we can see 8 and 10 speed controller options, i would absolutely love to have a sleeper 4.8 or hell even a 454 with a 10 speed 👌👌

[@mcmc8496]

By all indications this unit appears to be "Jam Up and Jelly Tight" (Thats a highly technical specification and industry standard that I borrowed from my 11yr old son) Thanks Holley for doing what you do!

[@shannonsisk]

Oh dang this is a game changer. I think there was only one other controller on the market and it was a stand alone one.

[@christophercarson4310]

Omg I can not tell you how excited I am for this release.. I assume this will be available on the Dominator platform as well? I have been waiting 6 years for this release.. I have been very hesitant to use the PCS controller.. You have just brought my project back on track.. Thank You Holley!!

They need too get mike rowe too do these promo ads. 😂

[@moose1992caprice]

This is pretty awesome

[@ProudlyNobody]

Can we get a 6L trans mount bracket adapter for the g bodys?!

[@babouinga]

can this system run a 6l80e on a transmission dyno with carburated engine for testing purposes?

[@adrianlaverick8040]

Can this be paired with your Gen V LT terminator x max?

[@sorryociffer]

So, does this piggyback the OEM ECU or do I need to have the Holley ECU to replace the OEM ECU first?

[@CamaroCade98]

With the 6l80 support now with the V3 software update and the controller, can the software tune the transmission for everything like you can with HP Tuners?

[@dreamspeedperf]

So does this mean we can now use 6l80 on our swaps?

[@rogerquintana4045]

Yes

[@carlosdelao9874]

@@rogerquintana4045 do we need to buy the holley terminator?

[@dalehall2993]

​@@carlosdelao9874 Yes.

[@nsmturbo5902]

​@@carlosdelao9874u need the terminator x max

[@farncoisbisson7737]

I would like to downgrade my reliability by going 8l90 instead of the 6l80 in my 2016. Found one local for cheap. Any option for a controller? My engine ecu is for a 6l80

[@danhall5218]

Is v3 out for terminator?

[@dalehall2993]

Yes!

[@gabrielsamano1807]

what if you have DBW ?

[@matttackel997]

wouldn't change a thing... TPS is monitored by the XMax box on DBW and Cable systems alike.

[@jglasco4445]

Can this be run with a carburetor sbc ?

[@pcmcobra]

great, if it worked.

[@escaladetay8974]

What issues are you having?

[@holeshot1721]

What about my 4l80e on my 350 5.7 1993 gmc 2500 pickup?
