GEAR,L/S 4RTH 17T
Layshaft fourth gear, 17 tooth, for the gearbox internals.
This is a layshaft fourth gear, cut with 17 teeth, from the gearbox internals. The description in the parts book lists it as GEAR, L/S 4RTH 17T, which is shorthand for layshaft fourth gear, 17 tooth. It lives inside the gearbox shell, riding on the layshaft and meshing with its mating gear on the mainshaft to give you fourth gear.

We don't have much more on file for this one beyond the tooth count and the layshaft/fourth-gear designation from the catalog. If you're rebuilding a box or chasing a worn or chipped tooth on fourth, this is the gear the parts book points to for that position.
Given how specific gearbox internals are to a given box and year, give us a call before you order so we can confirm this is the right layshaft fourth for what you're working on.
