I have heard that Pennzoil makes the GM Syncromesh and is the exact same blend.
I also found this. http://www.pennzoil.com/products/gear_oil/syncro_fluid.html
Can any prove, confurm or deny that this is true or not.
Also in eather case, do you guys mix the syncromesh with other fluids or use it strait.
Im thinking of doing this, but I have no problem shifting right now. But I have 170000 and dont think it has been changed in 100000 miles.
