Ok. I guess I'll change over to some Valvoline this weekend. Luckily it isn't very hard to change.

I just changed out mine the other day, so far it feels great.

hypoy c is a hypoid gear oil which is very harsh on yellow metals (like the brass your synchro is made of)

Could you name a couple of good fluids for people that constantly drag?

i talked to Andrew from andrewtech auto and i told him i was having a problem getting all my gears to go place im using lucas 80w90 and he told me to get rid of it ASAP cause it to slippery for my tranny and im running a 98 sti version 4 he told me to run straight redline shock proof oil.

now DS1...your saying you and andrewtech do the most tranny rebuilds in the country but you say not to use redline shock proof but andrew tech tell me too that leaves me at a very confused state cause i just ordered 4 quarts of it.

i plan on using it no matter what cause my tranny goes into gear really hard but doesnt grind so i know i dont have bad syncros just the gear oil im using is to slippery.

additional info would be great thanks

Damn can we just get one answer lol. "What tranny oil to use" apparently is on par with the meaning of life. 56 pages of contradictory crap.

On my last Suby I tried the cocktail for a little bit and it did seem to shift well.

I then went to straight Red line and it did just as nice....so I left it in. I will be putting it in my 07.

Have you read the Subaru owners manual? Factory recommends Subaru Extra-S, which is what you should put in there. Some other brands work as well such as the Valvoline and Motul products. The cocktail is merely a bandaid to try and cover up mechanical problems that need to be fixed.

Superorb....not really.

For those of us that had 2002-2003 MY cars from new they didn't even have EXTRA-S fluid available from the dealer when I did my first trans fluid change...so how could they have recommended it? What they recommended was a GL5 fluid and even Mobil 1 fit the bill.

I am assuming this is still the same for my 07.

Hi DS1, I have been read though this post and now here is my question before I go to do my tranny fluid change.

I have a 02 WRX wagon 5mt.
I living in Canada some how the winter temperture will become -25C (colder with windchill) and now, I would like to know what kind (brand) of tranny fluid is best for this kind of weather? Also what is the best for the rear diff?

Thanks for your info reply

Ben

EVERYBODY:

DIFFERENT DRIVERS, AND EVEN DIFFERENT MECHANICS, ARE GOING TO HAVE DIFFERENT OPIONS ON THIS SUBJECT.

Just because Andrew and Dylan have differing opinions doesn't mean one is right, and the other is wrong. It's simply a matter or preference.

Try to stick with one oil, not a mix. Going with something that falls under factory recommendation is a plus. And you will have to try a few different oils to see what you, as an imperfect human being with your own opinion, prefer in your particular car. The 5mts are finicky, and nothing is as fickle as the human mind... so different car/driver combinations are going to like different oils.

My view on this is that Andrew prefers shockproof based on his own experience. While it might be just fine, keep in mind that the minute a dealer sees something milky and/or colorful pour out of your tranny, they will likely immediately deny any transmission warranty claim you have. Dylan is probably trying to stick with fluids that fall under the manufacturer's specs as well as sharing his own experience.

Jhargis- I agree with you on the experience part, the experience I've had with the shock proof gelling up is the reason I don't run it.

The fluids you can run and that have been proven to work are:
75w90w Valvoline, Amsoil, Motul Gear 300 , Subaru Extra-S

Ben- Use the Valvoline, it stays almost 100% consistent in the cold weather

kike_ej20- For constant drag use I would run the Motul Gear 300

Hope this helps

-Dylan @ Ds1
For Valvoline/Amsoil, you mean synthetic or dino?

Ben: as per one of the 78446 posts, I used Redline 75w90NS. Tested at -25C morning start, worked well. Oh, and windchill doesn't affect the oil.. it's merely a measure of heat loss of a human body, not temperature itself

One grain of salt with the Redline I'm using. Shifting DID get better (3000 miles on it so far), however
a) I can't get downshift into first for speeds >5mph
b) upon every morning car start, there is a very delicate whine from the transmission for the first few minutes. Easily pinpointed as it goes away when I depress the clutch pedal.

Not sure if it's indicating anything negative. If so, I will do what Dylan said.

Forgot about that, thanks for reminding me.

I think the important thing is to not mix fluids and stick with a GL-5 rated quality oil. With that said, I'm running some cheapo Coastal GL-5 75w90 and the stuff feels much better than the cocktail that was in for 10k miles. The cocktail did feel good in the beginning, but it degraded rather quickly.

BTW, my last post sounded a little odd... I don't want to insinuate that either mechanic has better experience than the other. Edited.

Lol, its amazing how this thread has swayed. Check out my posts in this thread, from where I started out ignorant of how the stuff worked and trusting a senior member.. to where I decided to do some research and dump the stuff out of my transmission. My first post was on page 37. Wow

My friend's 2004 WRX was getting 3rd to 4th grinds above ~4000 RPM with only 11,000 miles on it. He doesn't abuse the car (I know 4000 RPM in 3rd is fast, but he shifts by the book to get there). He had Subaru replace synchro rings (I believe), under warranty, although Subaru of Milford sure wasn't happy about it!

If I recall correctly I think he had a grind after that (I'm fairly sure this happened, but part of me is skeptical of my memory), at which point I recommended Uncle Scotty's Cocktail, so both he and I put it in our cars (I drive a 1992 Subaru Legacy L AWD 5MT).

Of course he said it felt smoother, as most people do, and the cocktail only made my aging transmission feel just a tiny bit better (no more grinds with 260,000+ miles!). I have about 4,000 miles on the Cocktail, it shifts like **** but it doesn't grind anymore (it used to really easily).

After what you've said DS1, I intend to put Valvoline in both our 'boxes for 1,000 miles to clean it out, then I'm buying a 5 gallon tub of Extra-S and putting that in every Subaru I can get my hands on. So, my questions to you, DS1, are is this plan a good idea, and why would my friend's WRX have issues like that with so few miles and with mostly delicate driving?

im still here cockbreath

ive just deceided that there are so many idiots and asswholes on this board that just couldn't find their asses with both hands that i have given up and let the idiots follow the morons and the lemmings off the cliff and drown.

this thread is just another example of one asswhole coming in here and posting bull**** about this claiming all sorts of neboulous garbage with no real proof of anything
AND just because some monkey rebuilds transmissions all day does not mean that they actually know anything about what they are made of and why they really fail....which is 99% bad driving and drivers


FOR ONCE AND ALL
