I have also heard that GL5 is corrosive to the brass synchro rings. I ran GL5 in a newly rebuilt Audi transmission for about a week and saw brass in the grease when I drained it to replace it with Redline GL4 so there is probably some truth to this. I have used synthetic in my GT6 with D type overdrive with no problem, but I switched back to regular grease to be on the safe side.
I'm pretty sure the pump in the overdrive unit runs off the tail shaft so there probably isn't sufficient pressure to keep it firmly engaged at low speeds, regardless of engine RPM.

The overdrive should not work in 1st and 2nd (and reverse), there should be an inhibitor switch to stop this. You should use a GL4 spec oil in the gearbox. GL5 oils have additives in them that can eat away at some of the components (copper washers I think). I'm not sure what spec Mobil synthetic is, but I use castrol EP90 GL4 oil. cheers John __________________________________________________________________ Your favorite stores, helpful shopping tools and great gift ideas.
