View Full Version : Quick Tranny Fluid Question

06-28-2012, 07:52 PM
I have a 2001 x30 with the 1:5 tranny and am getting ready to do the service on it. I was going to use Dex/Merc to do the change but then read that using 14w-40 oil was actually better. Any thoughts on this?

If your v-drive is not noisey then you can stick with dexron III (or it's current equilivent). Some switch over to 15w40 if they are getting noises or rattling out of the transmission at idle speeds, the 15w40 will help "dampen" the contact of the gears and reduces the noise.
