With so much attention placed on getting your engine tuned and running well, it’s easy to overlook the importance of making sure your automatic transmission shifts properly too. And that’s doubly true when you’re talking about an electronically-controlled transmission that doesn’t allow you to fiddle with a vacuum modulated kickdown or a TV cable.

But the Edelbrock folks just made setting up your electronically-controlled late model GM automatic a whole lot easier with its new lineup of standalone TC Transmission Controllers.

Designed for the GM 4L60E, 4L65E, 4L80E, and 4L85E GM automatics*, Edelbrock’s TC Transmission Controller gives you the ability to adjust shift points, shift firmness, shift speed, line pressure, speed calibration, and more. Better still, Edelbrock makes TC Transmission Controllers that’ll work with carbureted engines, along with CAN EFI and the company’s own Pro-Flo/4+ EFI systems.

*The system supports GM 4L60E, 4L70E, 4L75E, (up to 2010), and 4L80E (post-1994).

In other words, it’s the perfect solution for hotrodders who want to swap a modern, electronically-controlled GM transmission into their rides and get all the performance, drivability, and fuel economy advantages that come with it.

The controller module is pretty much plug-n-play, with the auxiliary harness clearly labeled for a straightforward install.

Setting up the TC transmission controller is a breeze too. Once you’ve got it all plugged in and ready, simply download the free Edelbrock TC Tuner app to your Android or Apple device, connect to the TC module via Bluetooth, and the app’s setup wizard walks you through the rest. You’re not locked in either—from the phone in your pocket, you’re free to fully customize your transmission “tune” as you drive your vehicle.

Edelbrock’s TC Transmission Controller comes in three flavors:

  • EDL-36211 – For generic CAN-based EFI systems
  • EDL-36212 – For Edelbrock Pro-Flo 4/4+ systems
  • EDL-36213 – For carbureted engines

Edelbrock also makes a trio of Transmission Output Shaft Speed Sensor (TOSS) Adapter Harnesses for swap applications or to replace your old existing sensor.

  • EDL-36215 – 1989-93 RWD vehicles with 4L60E
  • EDL-36216 – 1989-93 4WD vehicles with 4L60E
  • EDL-36217 – 1994+ 4WD vehicles with 4L60E
