Simple question i have a g50-03 box i am currently overhauling prevoiusly it has had LSD fitted and also been had the caseing modded to get over the bad design problems that surround the clutch release fork. On the bench i have had to dissamsmble the box rear end to find out what i supect may be a damaged reverse gear (Ie what ever i do it wont select reverse but does select every other gear 4th 5th and 1st seem to be sticky). The bugger is i have now got the rear end off and the gears and syncro are in perfect condition no damage. I am at a loss as i am sure people know to disaamble the box further is a major amount of work. My question is why can i select 1st fine and not reverse? the only thing i can think of is that in some way the selector linkage for 1 and reverse is broken but even this makes no sense. I physically feals like its jamming the linkage!!!! Also my next question does anyone know a way of locking th input shaft that does not involve buying the expensive porsche tool? Also another question that has bugged me other the last few years is the ideal oil to use in a g50 ? porsche service centers seem to keep telling me different things and i dont seem to be able to find any information on the web that actually says any particular make or weight is better then another. Anyone know anything here ?
