Good point, Johnny. Any opinions out there on frequency of oil change in TC?In my experience, that pocket bearing, or mini needle bearing, or front output pilot bearing, rarely, if ever, fails. The overall split-case rarely fails. The Achilles heel of the entire case is the idler shaft retainer plate (thrust washer/plate thing) and bolt. If the bolt shears, or falls out, then the case grenades real quick. Otherwise, keep fluid in it and you'll be good nearly forever.
Some Australian friends say more frequent changes (30k miles) is a good thing for heavy use, high temps, etc.
