check/fill plug ss sc?

anyone know where the check and fill spot is on the ss/sc tranny? the owners manual didnt tell me **** except that it should not need serviced (that idea went bye bye when my tranny was grenaded the first time)
i have a hunch that some genius put ATF in my ss/sc 5 speed. any advice here?

I know for a FACT that in the LS(2.2) 5 speed they use ATF, it is lighter and since the sump is in the lower part of the transmission it needs to have ATF so it can work its way from the bottom of the trasmission to the top and lubricate all the gears(IIRC, of course). So assuming the SS/SC transmission is the same(I know it's a different model but may be similar), then it should have ATF in it anyway.

But then again I could be wrong and I'm trying to recall this all from my head.

On a side note I filled my 5 speed with Mobil 1 ATF.

If you take the driver side wheel off, both the fill/drain bolts are on that side of the tranny facing out. I put ATF in mine after the clutch install and it cause nothing but problems. Would grind a lot. Just today I put a more thicker manual fluid in and it cured all my problems. Although people say it's ok for ATF, I would go against it.

you guys need to use synchromesh in your transmissions. 5 speeds only, of course.

Thumbs up

Synchromesh is a much thicker fluid than ATF and would not only starve certain parts of the transmission of lubrication but could also cause problems shifting the transaxle.

Also, to let everyone know, for the '06 model year, it looks as if all automatic transmission cars are switching to the new Dexron VI standard. The fluids aren't backwards compatible so read your manual and be careful which fluid you put in your automatic. That and from what SI is telling me, -ALL- 5 speed Cobalts are getting the Getrag 287 instead of the SS/sc having a different trans (F23) entirely.

It is not okay to use ATF in our transmissions. You should only use GM synchromesh. Even you not so high horsepower 2.2/2.4 guys.

Getrags dont use syncromesh. Goto your local GM supplier and ask for "Saturn synthetic manual transmission Fluid" It's RED (which makes people think its ATF) and it has a very sweet smell to it (almost like honey). Cool thing is, the stuff is Cheaper than syncromesh, and its what they were filling the 02-05 Cavaliers with when they had their getrag 2-3 shift problems. Since i work for a Chevy dealership, my cost is anywhere between 6-8 dollars a quart, depending on what the going rate is and markup. If you get charged anything over 10 dollars a quart, tell em to stop being tight asses and not put a 200% markup on the ****. The 5 speeds take around 2 quarts (Give or take). Check your manual to make sure.

As WS Frazier said, the drain/fill plugs are accessed by removing the driver's side wheel.

And YOU MUST use the Saturn fluid.

I have pics of the drain/fill plugs, and the P/N for the fluid here

It's not worth taking the risk with the wrong fluids

Royal Purple Synchromax

Royal Purple Synchromax gear oil is what i just put in my cobalt, its about 8-9 dollars a quart. Its very good stuff though, my car switches into each gear smoother. Im also running royal purple in my engine, its really good stuff.
