Re: [AMC-list] overdrive issues

I've seen the results of years sitting under pines and trees around here.
Eventually the lube will drop off the gear faces and bearings then the rust starts.
It takes a while, but it does happen.
I've seen it a lot in Jeeps that see only seasonal use.
Guys get them out of storage to use in the winter and they have a howl.
Tear it down and find rust pits, usually in the top third of the race and on a few rollers of the bearing.

I've never pulled a manual trans apart that was rusted or pitted inside, not that was still attached to a car anyway. Have seen some that sat in the open off the car and got water in them. Even those are pretty resistant to internal rust due to all the oil slinging around for years, but have seen some of those rusted inside (heck, more rear axles!). It's not a bad idea to pull the cover off and inspect the planetary gearset though. It could have a nicked drum gear or loose planetaries. I've only seen an OD bad due to wear or a nicked gear. Or broken planetary shafts, of course!
