After my mom's `95 legacy dropped 10+ qts of fluid in the driveway, I got to
thinking. Does the automatic transmission vehicles hold more fluid than the
manual transmissions??

The reason I ask is that I'm going to drain my fluids and put in the "Uncle
Scotty Cocktail Mix". yet the total amount of fluids is 4 quarts, unlike
the 12 quarts for my mom's vehicle. Am I missing something here or do the
sizes of the transmissions make that much difference??

Yes, you are failing to consider that the torque converter and the
hydraulic system within the transmission hold lots of fluid. Normally
when you change the fluid in an A/T you only get what is in the oil pan.

If you go to autozone.com, in the repair guides, specifications, you
will see that they show much less fluid needed to replace the fluid in
an A/T than the actual capacity specified by the manuals.

Glad your mom's car is running again.

cocktail is for the MANUAL tranny.

Use only the OEM prescribed ATF for the
automatic.

Hi,

Yes, as others noted, ATs hold a lot more due to the torque converter.
Be careful when filling to follow the directions for checking the levels
carefully--w/ many ATs it's easy to over or underfill the trans if the
level's not checked properly.

On YOUR gearbox, what's this Uncle Scotty's Cocktail Mix? At first
blush, it sounds to me like something some shade tree guy w/ a six pack
came up with in a half hour that's "better" than anything the guys who
develop fluids for a living can come up with? I'd refill an MT w/ the
recommended weight fluid, either dino or synthetic, and forget about
mixing "cocktails."

I think I forgot to mention that my car is a manual transmission, although
I've mentioned that in earlier posts.

The "Uncle Scotty Cocktail Mix" is actually a mix of different transmission
fluids that many subaru owners have had success with in manual transmission
cars to solve or provent issues with the synchro gears. Check out this

I am missing nothing. I explained why auto transmissions use more oil,
but just so you feel good, I am a moron,

Hi,

Actually, I DID check before my initial reply. Let me repeat, "it sounds

How do you KNOW it cures synchro problems? How do you KNOW it prevents
synchro problems? Have these guys done the head to head testing the
engineers and chemists have spent a kazillion man hours, miles and
dollars doing?

You could go out there this afternoon, drain your gearbox, refill it w/
straight 30 wt motor oil (I'm NOT recommending anyone do this!) For a
while it MIGHT feel "better" (there HAVE been gearboxes that used
regular motor oil and some of them DO feel slick.) You can post all
kinds of glowing reviews based on your first week's "fantastic
improvements"--the Internet certainly allows the dissemination of
misinformation faster than anything we've come up with before! However,
I doubt you'll be back in 250k miles claiming "30 wt is better than the
75W-90 the factory recommends."

But that's just opinion and experience talking. What do I know?

I doubt that scotty's mix is all that bad. I also doubt it's better than
Redline 75-90NS (especially after a few hundred miles of 'wearing
in/cleaning).

And are we talking about older trannies that have a lot of wear? might
need a change anyway? have moisture built up in them? Or newer ones? or
trannies with actual problems but not torn down/inspected yet? what if a
different or heavier oil is just masking a real problem?

Uncle Scotty knows his stuff. Many people used the cocktail for years
with nothing but good results. I personally have run it for about 10k
miles so far, and my trans definitely feels better than what it did
with the original fluid... keep in mind that I beat the crap of my
transmission auto crossing. I searched long and hard for *anything*
negative about this cocktail, but didn't find a single substantiated
negative review... except ones like yours from people who never
actually tried it.

Your 30wt analogy is invalid. Motor oil is far from transmission fluid.
Uncle Scotty's cocktail IS transmission fluid, it is different
transmission fluids mixed together, which allows you to gain the
benefits of all of them... a healthy balance if you will.
