The topic of the Corvette’s Z-51 E-Differential has interested me since I first heard of it being added into the powertrain of the Z-51. What is an electronically controlled diff? Here is a generic explanation :HowStuffWorks "Electronic Limited Slip Differentials "
The GM unit is a bit different in so far as it uses hydraulic pressure in a stand- alone system within the rear diff. unit to micro adjust pressures to the diff’s clutch pack to suit the drivers demands on the vehicle. Tadge Juechter speaks to the Z-51 E-Diff here on the Autoline Afterhours interview from last week.

What I am interested in finding out is: Exactly how the system works and if required, how is it serviced? My intention in starting this thread is for us to add to our knowledge of this sub-system and in time figure out exactly how it works, what it requires in the way of maintenance? I am also interested in finding out how reliable this system is, and how well it performs? Another aspect of this topic is: Does the cooling vent identified as the one for the “E-Diff” on the rear flank of the Z-51 actually one that cools the hydraulic fluid that drives this system? Where is the pump for this system? If you can add insight to its operation and performance please do.
