97 SE 4x4 OD slipping

[Jerrydog]

Well with 14 years on her and 305k miles Im possibly looking at my first real repair on my Path. Last night the OD started slipping and later 3rd started to as well. She has plenty of fluid no leaks etc, always maintained and serviced by me.

Anyone give me any insight if this has happened to them and or costs for tranny work?

Thanks
