Synthetic Lubricant Change Interval?

[cliffn]

My wife and I have a 2000 Century Class (bought it used) which has Eaton Fuller ten-speed auto-shift. The transmission and rear end in this truck have synthetic oil in them. When (or how often) does this oil need attention? Thanks for your help.

I would check your owners manual for there recomendations. If that doesn't work contact your dealer.

Lots of good info to be found.
IIRC, 500K miles is the recommended drain/refill interval for synthetic gear lubes.
