What is DCCD?
DCCD stands for Driver Controlled Center Differential. Explanations for this system are complex and tend to go about like this: (Start at 3 minutes in)
If we put aside the highly technical specifics (and semantics), the core concept is that a DCCD equipped transmission can adjust the distribution of power between front and rear wheels to allow the car to perform better in any situation. Without a DCCD controller, the differential doesn't have anything to tell it what to do, so it will default to a fixed setting that sends more power to the rear than front. More about DCCD controllers in our next post.
How do I know if my transmission came equipped with DCCD?
Just having a transmission with 6 gears doesn't mean it came with DCCD. Conversely, just because the transmission has 5 gears doesn't preclude the transmission from having DCCD. Take a look at the plug on the top of the transmission and see which style of plug it matches.
Why would I want to upgrade to a DCCD Transmission?
