i changed the tranny oil from redline to motul 300 and all i can say it 's very very different , motul oil is much much better than the redline crap . in cold mornings i have no issue with shifting , beeing a bit thiner, but you can still feel the viscosity in the smoothness of the shifts .
motul seems to be right oil for this tranny (well it meets the specs too , redline does not).
i found it cheapest here 12.5$/litre and only 6$ shipping (3L are needed since the tranny takes ~2.6L)

After $170 in fluids on a 5k car, I'm switching back.

No discredit to Motul but there's something strange about the OE fluid that makes it very thin at cold temperatures. Another BITOG member and I have been emailing back and forth with findings and even though Motul is less viscous than stock @ 40C and has a lower pour point per the tech sheets, stock is much thinner @ 0C.

I'll be swapping back to stock and keeping the Motul in a container where I'll swap back to it in the spring. There is no disadvantages to doing this as long as the bottle is kept tightly shut and no contamination gets into the oil.

Glad to hear that you like it though. My feelings were exactly the same.

So your issue is solved?

I'm getting rid of the Redline also. Cold mornings and Redline do not go well together!!

RKA

Probably won't do it until the spring, so I'll ask you again in the spring how the winter went (and if the tranny still lives).

Unless the car is a track-only car I don't see any reason for any fluid other than OEM.

we carry and use the Motul Gear 300 often....good stuff

here are the specs for redline and motul:

Motul is thinner at lower temperatures(hence easier shifting in the cold mornings), however redline has much better flashpoint(better oxidation stability). I wonder how hot our tranny gets anyway?

I wonder what are specs on OEM fluid(pentosin right?)?

RKA

I've actually been pretty happy with the OEM fluid. No real cold shifting issues unless it goes into the single digit...and then it's like syrup, but that's to be expected...even the clutch doesn't like single digits. But now I'm getting to the point where I think the fluid needs to be changed...and the OEM stuff isn't cheap. I wouldn't be surprised if it ran $20 a quart at the dealer.

OEM is $26 a liter retail. Dealers will usually markup from this. Local here is $33 a liter
