Can someone please confirm the fluid capacity of the six speed transmission in a 1996 Z28?

Is GM Synchromesh still the best fluid to use?

Thanks very much,
Rick

 

4 qts... I use Mobil1 synthetic.Also Honda is good.

 

Just under 4 quarts. My dad has mobile 1 in his WS6, and I have the gm stuff in mine, and mine shifts alot smoother than my dad's WS6....

 

Thanks for the info, guys. It's just what I needed.

Hey SpeedDemon...How do you like that SLP clutch?

 

Is the royal purple stuff worth the price??

 

O'reilly's told me 8.8quarts. now every time i get above about 4k RPM's fluid spews out the vent hole and onto my Ypipe. how much damage is this causing to my tranny?

 

how the heck did you get 8.8 quarts in it? you fill it through the fill hole till it comes out?

 

It drives like stock, not chatter or anything, but I'm not sure how much longer it's going to last. I did a hard run through 4th gear the other day and the 3-4 shift was soft as hell, so who knows. I mostly drive it easy though, so its holding fine.

 

Thats what i wanna know! How did you fill that thing?

 

i'm wondering if he had it out and laying on its side, or if he filled it through the shifter hole......

 

yeah it was on its side, it was out for the new clutch install. and no i didnt get 8.8 quarts in, i got maybe 5 or 6, just filled it all the way up.

 

Why dont you just lay under the car and open the fill hole to let out the excess fluid?

 

because i'm not sure how much has been forced out of the vent tube and i dont want to have to little fluid in it.

 

If you open the fill hole and fluid comes out, then there was more than enough in there and you just drained the excess. If nothing comes out, then add a little bit.

 

most people will dump 4 quarts into the shifter hole before installing the shifter and your done...
