What is DCCD?
 

DCCD stands for Driver Controlled Center Differential. Explanations for this system are complex and tend to go about like this


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.
