Default DTE Differential Fluid Help

Sorry guys wrong section. Moderators please delete.

I have a DTE 4:10 rear and my car is in the local Chevy dealer for GMPP warranty work. The real axle seal is being replaced and I will need to put Redline 75-140w fluid back in but my DTE instructions do not say how much friction modifier to use or what kind. It simply says to use there premixed Redline 75-140 and I need the fluid quickly for the dealer. The dealer is waiting for my response and I can't reach DTE on a Saturday. Any help would be greatly appreciated.

Wow the dealer does not know about the 3 or 4 oz bottle that says additive made by GM? the bottle comes in a blue and white box 1"x1"x5" kinda weird.

Yes, but this is a DTE Rear that requires Redline fluid and the question is about the use of friction Modifier with Redline fluid and how much. ALso if any of you ex C5 guys know where I can get Redline fluids in a hurry?

Default 13% DTE blend

Craig,

The info on my DTE stage two says to use the Redline oil "w/ the 13% DTE blend of Redline LSA". Not sure exactly what that means but Redline may know at 707 745-6100 in Benica, Ca. - between San Francisco and Sacramento, Ca. Otherwise have to wait for DTE to send asap on Monday.

I just stepped in the office for a minute to pick up a few things, so I thought I'd answer your question directly here, since you're in a time crunch..

Your DTE IRS Differential requires 2 bottles of Redline 75/140w synthetic lubricant to fill it and you'll also need to add 1 oz. of Redline synthetic LSA to each bottle to bring it up to a 13% blend needed to support the HD preload springs of our own design we use in our clutch packs.

FYI~ Do NOT ever use the GM LSA additive with any aftermarket Redline synthetic lubricants, as it will not remain in suspension w/ the host lubricant to remain blended correctly, which effectively starves the clutches of the proper lubricity properties they need to survive in a HP environment...leading to premature clutch pack failure.

The new 2009 differential care/maintainance instructions that we send with each differential shipment will include this information and you can purchase the necessary lube either from us, Jeg's, Summit Racing or anyone else that carriers this type of axle lubricant.

Hope that helps.

Just so I understand the Redline Fluid must have some LSA in it and only requires the extra 1oz per quart to bring it up to 13% ?

Default Yes

That is correct as I understand it. You will need 2 qts. and the differential will hold 1.69 qts. Each qt. having 1 oz. added to it.
