I'm looking at the 833 I want to get rebuilt and trying to decide what needs replaced and if I can even find it. the TSM says replace any gears that have excesive wear, what's that? the only wear I can see is on the 3-4 clutch gear, it's noticable but even and smooth so would that be considered excessive? all I know about the tranny is it worked when the car got wrecked. I'm not sure how to figure what amount of wear and in what places will give me a problem, maybe there is a place with pictures of worn gears to use as a reference?
