|DHD 116-610 Dirty Alli-Locker 6-Speed Torque Converter Lockup Switch|
The DHD Dirty Alli-Locker torque converter lockup switch won’t leave you second guessing if your Allison torque converter is fully locked up or not. DHD built a simple kit that overrided the TCM and allows full manual control of the Allison torque converter clutch at any time. There are two modes, manual and automatic. Automatic mode is required for daily driving, but in the event that you want to immediately lock or unlock the converter, you can do so, at the flip of an easy to access switch. Manual mode will give user control, which is great for sled pulling or drag racing events.
There isn't any need for boxes or interceptor modules that need to be mounted under the hood or on firewall. Installation is a breeze with a simple wire harness that will need to be routed and interfaced with the TCM. After that, a switch is provided that you can mount in dash with factory hardware.
Note 1: This is an off-road/competition use ONLY product. It was solely designed for closed course drag racing or sled pulling events.
Note 2: Always remember to flip the toggles switches back to stock mode when not in use.
Note 3: This product is offered with a direct "factory" mounting box that will work on all 2001-2007 Classic series Silverado & Sierra pickups. Or if you prefer, we also offer a universal box that you can mount anywhere in the cab. Make sure to select the proper drop-down upon checkout for your mounting preference.
