My new 2008 Scion xD 5 speed specs 75W GL4 for the transmission. There is no PM schedule for the transmission fluid so I am guessing that the mfg means to say that this is a lifetime fluid. I have no intentions of leaving it in there for the life of the car. Any ideas, other than the dealer, of where to obtain a good 75W GL4 fluid?
75W GL4?

Redline, Amsoil
This is strictly a 75W, not a multiweight. Looks like Redline D6 ATF satisfies the API 70W/75W GL4 requirements. I'm still not sure if it is OK since it is an auto transmission fluid. Hmm...

I'm not even sure what a "75W" is. There really is no such animal IMHO.

Lots of car companies and gear oil companies play fast and loose with these names. In my world, 75W only means as stated on the chart.......and no max viscosity. It makes no sense.

You're right, it doesn't. I was kind of thrown for a loop when I read the manual. I may just have to take a look at the dealer fluid and see what it says.
I would think that something like Mobil-1 synthetic 75W-90 would work fine.
The range implies that there is a bit extra heat tolerance to that fluid.
My 2¢

Let me know, I got this from HQ:

AMSOIL does not have information for all the 2008 vehicles yet. If you can supply me with the name or part # of the fluid they are using, I may be able to cross reference it.

Toyotas have for years recommend 90wt gl4/gl5 gear oils for all their FWD and RWD manual transmissions.
Since this is a 5 speed, assuming(identical) Corolla/XB powertrain, I would just stick with the 75w90 GL4's from Redline or Amsoil. MT90 and MTG are easy choices.
Since Toyota has adaped to 20wt motor oils and 75w85wt 'end gear oils, they might've come out with a slightly thinner gearbox oil. Slightly thinner improves shift quality when cold and improves MPG. Did Toyota create a 75w85 MTF for 2008????
I would also reread the owners the factory service manuals. Seems like a typo. '75w' doesn't have a maximum weight range per SAE J306. This means you can use ANY 75w80, 75w85, 75w90, 75w110, 75w140........ Thats just too [censored] vague for Toyota tech writeres.
You can sample UOA your old fluid for a better answer.
I also wouldn't jump to an ATF, since it seems too thin for the application history.
I also would NOT bother with any GL5 gear oil like M1.... These 'lsd' gear oils just aren't synchro happy.

This was the only thing I found which specificaly mentioned 70W/75W GL4 with no other viscosity number. Maybe someone can explain exactly what this one is.
undummy,
The 75W appears a couple of times, and just as that, with no qualifier. I was surprised myself. I'll scan and post a copy of that page.

Ideas?
Maybe its like a syncromesh fluid?
The "LV"(low viscosity) sticks out. A UOA or VOA would be best, or stick with the OE fill until you find a datasheet on the fluid.
There is also a SAE paper on this fluid. It is an MPG fluid.
How low did they go with cst? and, is it backwards compatible with all their other transmissions?

That's lower than Dexron VI viscosity territory.
I'm going to try to get by the dealer tomorrow and see if they have any in stock. I'm curious now. The car only has like 20 miles on it so I won't be needing this for a LONG time. Bob's already has me looking for new fluid, jeez!
unDummy,
You mentioned MPG fluid, as in fuel economy kind of thing?
Pablo,
So are we talking about an ATF fluid which is GL4 rated? Like the Redline I posted a link to?

I'm not sure....but Redline could be ahead of the game on this one. More research needed.
I'm not a 'botique oil' fan, but would use Amsoil if the specs are right, the price is right, and it's readily avilable.
I have an NV4500 5 spd transmission which is spec'd to use a GL4 and I use the spec'd Castrol Syntorq, which is also available at elevated prices by the quart thru Dodge as a Mopar oil for that transmission. Standard Transmission also has it for a bit less than $60 a gallon. Check around to see if anyone else is using it in your application.

Its a low viscosity gear oil. I won't jump to conclusions but I doubt that Toyota would drop from a 15cst gear oil to a 7cst ATF for their manuals.
T-IV is slowly being replaced by WS, which is in the 5.5-6.5 range, where T-IV was ~7.5.
SAE90 rearend gear oils are slowly being replaced by Toyotas 75w85 GL5 rearend gear oil.
5w30 has been changed to 5w20.
A couple CST here, a couple CST there, an across the board increase in MPG; yes as in saving fuel and reducing byproducts from its combustion, and its about time. Why? because the move down the viscosity ladder means the move up in the oils group# along with using newest additive tech!
Did Toyota simply produce a 75w85 GL4 gear oil, like Nissan? or a SAE30 MTF like Hondacura? or an ATF thin MTF like some of those VW/BMWs? Only a VOA will tell.
And, I would NOT substitute ANY fluid until you either VOA the OE stuff or read the SAE paper. Tossing in an ATF where a 75w85 fluid is needed might be detrimental to longevity. Tossing in a 75w85 or MTF/MTL where an ATF is needed might be detrimental to shift quality and performance(HP/MPG).

It probably means that the 75 is required/spec'd at operating temps - therefore a multi weight with x-75 would be perfectly safe, and even better.
To me, that manual is saying to use a 75W-anything. I'd use a 75W-90.
