Awesome. I’ll be using it shortly in some Volvos due for driveline services.
So do you think it will be better than the OEM fluid for the Haldex? I have another change coming up on the Tiguan.
The Haldex is just an electrically-controlled wet-clutch. There’s not really any difference in fluids. The RedLine is way cheaper than OEM so go for it.
Just seems to be a "regular" manual trans/gear oil would be different than a wet clutch fluid was really all. In the FB group I mod (Alltrack/Sportwagen), someone was concerned that their shop used Motul 75W90 gear oil in their Haldex...I figure they just goofed and did the r. diff but folks were losing their minds to stop driving it etc. b/c it will be damaged...based on this I'd say no, may not work correctly with an oil of that viscosity vs. what is supposed to be in it but shouldnt' damage it.
I wonder why VW doesn’t state that it’s a regular gear oil? I mean that’s what they say for the two differentials. It’s odd.
If Red Line says it works, why wouldn’t it? I’m sure they know what the inside of a Haldex coupling looks like. Synchros in manual transmissions require similar fluid characteristics to clutch packs. I don’t see why it wouldn’t work.
Because Haldex fluid isn’t a standard 75W-90 like the diffs.
.
I wouldn't run Motul Gear 300 75W-90 API GL-4 & GL-5 (> EP) in a Haldex unit.
Never ever. That said I'm still not convinced with Redline MT-LV. Haldex units
are not MTs.
Granted, I have no issues to obtain VW G 055 175, Ravenol AWD-H, Liqui Moly's
offering or BorgWarner/Haldex's own fluid.

What makes the Red Line MT-LV 70W/75W GL-4 special?
Neither would I but I don't think it will damage it if it's changed out shortly after.
This sort of reminds me of me running DCT fluid in the manual on my son's Focus. Seems odd. Works great.
It’s a LV GL-4 not a GL-5 which is what the diffs call for. Same reason you wouldn’t put a hypoid gear oil in a manual transmission.
The DCT fluid is what goes in the Powershift 6DCT250 which is a dry-clutch DCT. The internals are that of a manual transmission, so that’s why the fluid works in a manual and the DCT. The fluid does exactly the same job.
But the clutches in the Haldex surely aren’t dependent on the viscosity, at least not here. Could I use any GL-4 of the appropriate grade? That’s pretty much what I use in the ECHO for a manual gear lube.
I just don’t see what makes the Red Line special but not some other GL-4 product.
I’d assume its characteristics are just well suited to Haldex coupling use.
It’s clearly not identical to all other 70W/75W GL-4 gear oils – I haven’t found a gear oil which transforms the shift quality of certain manual transmissions like the Red Line MT-LV does. Factory gear oil in my Fiesta ST wasn’t bad, Liqui Moly 75W made it baulk and feel horrible, Red Line MT-LV made it smooth as butter. Huge differences between three 70W/75W GL-4s.
Haldex oil is 75w with same ZDDP package like other MTF and engine oils, but highly additived, GL4'ish. These are some similar:
- RedLine MT-LV 70/75w
- Toyota LV 75w
- Elf NFX 75w
- Ford 75w D2
- Honda MTF-3 Ultra
- Castrol BOT 303
Some syncromesh could be ok too, but additive a few more weak. Other MTF GL4 and GL4+ same, but additive not ZDDP based.
- RedLine MT-LV 70/75w
- Toyota LV 75w
- Elf NFX 75w

So any of those would be an acceptable fluid?
Most likely.
As it tuned out this heldex fluid is not that "special" after all... Just a low viscosity Gl4...
...especially if your car maker defines a service interval for it instead of "life time fill".
*edit* I found a VOA of the redline MT Lv in this forum, the additive package of loads of Calcium, Zinc and Phosphorus.. It's pretty much the same darn thing vs VOA of haldex fluids (even the viscosity is pretty much the same)

Nice work.
Yes specially top 4.
