At HGM You Can Count On
1 - The Perfect Harness
Avoid the pitfall of budget priced controllers requiring you to "cut and solder" to get your harness installed. At HGM we custom engineer plug and play harnesses for every transmission. So whether you need a 4L80E controller
, 4L60E controller
or any other transmission controller you'll know connecting your harness will be hassle free. Plus, we make sure that every part of the wiring harness is labeled so you don't need to dig into manuals asking questions like "what does this color wire do?"
2 - Setup Ready-To-Go
To make the task of setting up your transmission easy we provide factory pre-set settings for each transmission. This allows your transmission to run with carefully selected settings to optimize its shifts. However, you can personalize your shift points and fine tune your transmission settings by making adjustments from those factory pre-sets.
3 - Easy Kit Configuration
We make choosing your kit as easy as 1-2-3. Did you know that the 4L60E transmission controller kit varies depending on the number of pins your 4L60E main plug has (13, 15 or 17)? Did you know the 4L80E transmission has an early and late version? These differences are important as cables and connectors need to be right for your exact transmission. At HGM we developed an easy questions/answer configurator that creates the kit that works with your transmission.
