Synthetic ATF in transmission
Can the newer synthetic ATF's ie: (Mercon IV or others) be run in a KDX trans, or should one only use the Type F ?

I guess you could, but why? The MOM says to use 10w30 or such. The Gorr maintenance book notes that gear oil lubes the trans well, but is thick enough to slow it down. He suggests 10w30 or even 10w40 for normal applications. I guess some racers may use ATF, but he (Eric Gorr) cautions that it is replaced after every ride. In summary: The lower the viscosity, the more often it needs to be changed. I use synthetic oil in my car, just to prolong my change intervals to 5000 miles instead of 3000. I don't see the benefit of using syn ATF fluid in a trail bike. But, then again I am probably wrong.

ATF smooths the shifting of many trasmissions, that is why many people use it. As for the viscosity issue just cause something is thinner does not mean it needs to be changed more often. If that was the case many cars using 5w20 would need there oil changed more often than a car using 10w30.Automatic transmissions are subject to lots of abuse,heat and lack of maintenence. Ask someone when they had there trany fluid changed...most times it is not often. And most transmissions go the distancedanfree wrote:I guess you could, but why? The MOM says to use 10w30 or such.
