Leaf spring top plate
Top plate for the leaf spring in the gearbox inner cover and selector mechanism.
57-4290 is the top plate for the leaf spring used in the gearbox selector mechanism, found in the gearbox inner cover and selectors figure of the parts book. It's a small stamped piece that works with the leaf spring to keep pressure on the selector mechanism inside the gearbox inner cover.

This one shows up in catalog listings from the early 1970s under both the modern 57-4290 number and the older T4290 designation, so if your parts book still uses the letter-prefix form, that's the same part.
It's a minor piece but part of a system that needs to hold spring tension correctly for the gearbox to select gears properly, so it's worth checking condition when you're in there working on the inner cover and selectors.
