ELSD fluid Part Number
Does someone has the exact part number for the E/Diff module fluid?
Please it's the module fluid and NOT the Differential Fluid. (Sorry if someone posted) just could not find it without getting a straight answer from the other posts I found. |

Ok I found the answer..
The ELSD module takes ATF. "and needs a computer/scanner to actuate its pump and valves to purge out air, when it is refilled" Reference: https://www.corvetteforum.com/forums...two-hpdes.html Has anyone serviced this? Do I even need to worry about changing it out after track days? |

Interval maintenance part like the elsd clutch pack fluid is. You are supposed to change the cluth fluid at 1500 miles if you will be tracking. |

The ELSD fluid is not changed unless needed, so it's not a regular maintenance item.

I've been trying to find the answer to this as well. Seems like everyone is running 75w90 with no issues. Though the 2019 manual for the Corvette says to use DEXRON-VI ATF in eLSD models (Z51, ZR1, Grand Sport & Z06).
https://my.chevrolet.com/content/dam...ers-manual.pdf see page 321

Spoke with Valvoline's Tech line (1-800-TeamVAL) clarified that the eLSD takes ATF fluid. Dexron VI ATF or Maxlife ATF.

ELSD
It looks like you have the right fluid for the ELSD system. The rear differential fluid is different than the ELSD fluid. Can you tell me how to change the fluid and how often? It would really help. Thanks

You do not need to change the fluid in the eLSD module. Diff only.

The fluid is cycled thru the module by a pump in the transmission. The ATF in the eDiff is shared with the transmission and is the fluid used to lubricate the transmission (at least in my 1LE SS it is)

So the actual differential fluid is the 80/90 LSD fluid......?
I have to have mine checked....9300 miles

there seems to be quite a bit of confusing information being exchanged here
The transmission fluid, either M6 or A10, circulates through the transmission, air to fluid heat exchanger at the front of the car and through a fluid to fluid heat exchanger in the differential housing. If everything is good, the differential fluid and transmission fluids do not mix. There is a 3rd fluid in the ELSD actuator, which also is isolated from the differential fluid. There does not appear to be an interval for periodic maintenance of the ELSD actuator fluid. both the transmission and differential fluids have prescribed maintenance intervals based on vehicle usage, ie track or street hope this helps
