It's a good idea to lubricate any odo cable you buy. Use a graphite cable
lube such as Kable-Ease. Careful it's messy and will stain. Use a blob
of synthetic grease (NEVER regular grease) on each end, to prevent the
binding on the cable and reduce "bouncing".
Did your entire cable shear halfway up, or just the core? If the core,
perhaps there was a tight bend or kink in that spot. Be careful when
routing the new one, keep all curves as gentle and consistant as possible.
If the cable sheath wore through, then it must be rubbing as the engine
moves on its mounts. My '79 with O/D has a support on top of the tranny,
like a cable clamp IIRC, that holds the cable away from the trans and
engine. Also, it would be a good idea to install the grommet where the
cable passes through the firewall.
