I recently aquired a borg Warner R-10 overdrive unit, but after tearing it down I found that the planet gears where pretty well shot. At least one of the shafts holding a planet gears into the cage sheared off, and the gear was pretty much destroyed. It didn't seem to do any damage to the ring gear, and the sun gear has some wear, but it looks like this could be from normal use. Whether it is or not, I don't no if it's worn badly enought to warrant replacement - please advise.
As far as the planet gears go, I have a couple of questions:
1.) would a machine shop be able to repair the gear set for a reasonable sum?
2.) If I have to find a replacement, could I use a gear set out of a non-GM overdrive? I know the bolt pattern is different, but with the gear cage interchange? overdrives from ford cars seem to be much more plentiful in my area.
