brought my car in because of a clicking noise and turns out to be broken gear teeth!!! its gettin rebuilt and i was wondering if it would be ok to use the scotties mix or should i use something else after the rebuild? also, since the intercooler, exhaust and down pipe are off it right now, any one got cheap ones for sale? thanks
not sure, my wife actually drives it 90% of the time, she said she had grinded it then started hearing a noise, then the noise became a click and got louder every day. i thoght maybe she tried to put it in first while still moving, thats why i want to use scotties, i hear it makes it easier to shift, even first gear.
Do NOT use Scotties in a new or newly rebuilt transmission. Its for prolonging dying transmissions, not new ones.
my tranny was rebuilt once before/ 40,000 miles ago. i dont even know what was used, it was done at a kennedy transmission so probably oem or some generic brand. i need this to last longer then that!
I would personally run Subaru Extra-S that is for sale at Morries Minnetonka Subaru. That's subaru OEM fluid and many many people have had good luck with it. I am personally running Fully Synthetic Valvoline 80w90 in mine at the moment without a hitch.
I'm using Valvoline conventional (non-synthetic) 75w90 gear oil and it's working great. You can get it at Napa. Personally I'd run either the valvoline conventional gear oil or the subaru extra-s, not scottys mix.
"Scotties mix"? FWIW I recently changed my rear diff & tranny oil out and used mobile 1 75w-90. So far so good.
Use Scotties on everything, Diff's, trannies, it is even a valid substitue for motor oil. It is just about the best thing ever.
It's a mix of the following for subaru 5mt transmissions, 1qt Redline lightweight shockproof 1qt Pennzoil Synchromesh 2qt Castrol HypoyC 80w-90 Originally thought up by someone on nasioc.com with the username "Uncle Scotty", hence the name Uncle Scotty's Mix or Uncle Scotty's cocktail. I can't find the orig thread on nasioc, but here's some info http://forums.nasioc.com/forums/showthread.php?t=920674 When I tried it, it worked ok for a couple months, but broke down kinda fast and actually made shifting feel worse than just normal gear oil. Since then I've stuck with quality conventional gear oil with the grade and viscosity t recommended by the owner's manaul.
It actually is partially motor oil. Synchromesh is 5w30. Hence why it actually SUCKS for Subaru transmissions.
The cocktail separates when stagnant, The fluids do not mix well with each other. Plus if I recall right none of the fluids(possibly one) actually meet Subarus specs for the transmission. Subaru has also in newer(at least '03 up) has began putting a written warning in owners manuals to NOT mix fluids in the transmission. The pic is of the cocktail that has separated after sitting for a period of time. Pic from post #1601 from the thread that prezawagon posted.
I use valvoline non synthetic on my forester, and when I change it next time I will be going to extra s.... stay away from synthetics they are too good for subaru transmissions.
I see Uncle Scotties mix as a bandaid. I would throw in Motul 300 on a NEW tranny. I would NOT use Scotties mix ever. If it grinds and the Motul 300 don't fix it, I FIX the tranny. Synchro no good.
PLEASE tell me this is sarcasm. the ONLY thing the cocktail is good for, is improving ease of shifting. but it's aweful on bearings and such. the RX trans in my wagon has a crapoload of miles on it (been in at least 3 cars...). shifting was a little tough, so I switched to some valvoline 80-90 and 1/2 qt of Rislone engine treatment. this improved shifter feel quite a bit. then I switched to the cockail. shifter feel improved only marginally. 6 months later, the trans started developing some pretty nasty bearing noises :eek3:. I switched to straight HypoyC 85-90, and the noises have gone away entirely. shifting is quite tough when cold....but I'll take my time and not burn up the trans, thanks. Short version: don't waste all the money you just put into a rebuild by killing the trans with terrible lube. use a dino gear oil. I'd use Valvoline.....as I've always had great luck with their stuff.
I tried about $200 worth of gear oil in my 6mt trying to make my 1-2 shift better. Dino oil is where its at. I would use Extra-S, or at the least Valvoline 75-90 dino. I used Amsoil Syncromesh, and it was actually very good when hot. The tranny didn't like it cold, but with dyno oil and my dying 2nd gear balk ring, the tranny doesn't like hot dino oil. The syncromesh isn't so bad as a gear oil. It has a ton of friction modifiers in it so its not like running a 5w30 motor oil. Not even close. Get some Extra-S or some 75w90 name brand stuff.
But it IS a 5w30 weight oil!! It does have many many friction modifiers, but at the end, it IS 5W30 weight.
I ran it for quite a while, and the 6mt liked it. Just not when 20 below zero. It works a hell of a lot better than any dino oil when hot. The actual weight doesn't matter as much as the friction properties in shear, hence the Amsoil working so well. I still recommend the Extra-S though.
I ran straight syncromesh in my car for a straight 100K miles, no joke, no problems. I only changed it because I felt bad. LOL.
Of course it was sarcasm. I read the horror stories after I was thinking about using it and you fine folks showed me the light.
