Rear Diff Fluid

[mfcentex]

Where is this specified and how is anyone supposed to get it to that level? It sounds like others are overfilling it by filling it till it weeps out the top hole.

And how do you get an accurate fill level if you back up a 5BW onto ramps to do this procedure?

To change the transmission fluid, you would need to get whole car lifted. You would want to get it level.

You can suck out 8 ounces after it is full. This is related to the transmission:

Transmission fluid level MUST be 3.2 mm (1/8 inch)below (1) the transmission oil filler plug. This can be done by one of the following two methods:

• Bend mechanics wire to 3.2 mm (1/8 inch) to check fluid level. Add or remove fluid as necessary.
• Fill transmission until level with the bottom of the transmission oil filler plug hole, then remove 240 ml (8 ounces) of fluid.

Oh, so the 3.2mm below is for the transmission and not the ediff? So is the proper ediff level to be filled up to the plug?

Yes, I think there is some confusion in the thread. It looks like someone posted about the transmission at one point. The rear differential is standard, fill to the bottom of the hole. Manual transmission needs some expansion room, since it is basically using ATF.

Are you talking about the rear differential or the actual elsd?

Yes, I changed the electronic limited slip DIFFERENTIAL fluid.

Assuming the CT5 is the same, this is the process for the CT4 (note step #3 in Installation Procedure).

I’m confused. Doesn’t the 5BW only have a eLSD? So there is only one thing to worry about back there with the specific Delco 10-4131 fluid. There isn’t anything else differential related to worry about correct?

I assume all the other differential capacities mentioned in the manual pages are for the other ct5 variations.

The eLSD is a completely different portion compared to the rear differential. I believe it's only dealer serviceable.

You can only change the rear differential. The eLSD is separate.

It seems from the around 1.5 quarts people are putting in, it is the eLSD fluid getting replaced.

I never said elsd COOLER or elsd CLUTCH fluid, it's not clear to me how you've gotten so confused...

Just trying to clear up your misstatements for others. Not confused on my part, I realize that you can't change the eLSD (not easily). You just changed the rear differential.

That table is for referencing the option of the vehicle being serviced. Not necessarily the exact part/fluid. It is saying vehicles equipped with an eLSD use 1.5 qt in the rear differential.
