Upgrade


Comes with controller and wire leads for new features


Do you have an old-style (91-93) solenoid connector harness on your transmission? This early harness has a problem with leaking fluid at the pass-through connector and GM recommends upgrading to the new connector and wiring harness. Because of this, we don't provide a wiring harness for it. If you have one of these, you'll need to upgrade it. The easiest way to tell if you have one is by looking at the solenoid connector on the transmission. If there is a bolt hole in the center, then you have an old-style harness.
Use the buttons below to make your choice, then click Next to continue.

Do you need an updated internal wiring harness?




Do you have a pre-1994 Bosch pressure control solenoid? This solenoid isn't compatible with our controllers, so you will need to upgrade it to the 1994+ Holley solenoid. The older Bosch solenoid is silver, while the newer Holley solenoid is black. If your solenoid is already black, you have the right one and doesn't need to be changed. The required bracket is included with purchase.
