This category includes washers, bearings, and sprag components for Jetaway automatic transmissions used in GM vehicles between 1956 and 1964. These parts are used to control axial play, support rotating components, and enable one-way functions in the transmission.
During service and renovation, it is common for these components to be carefully checked and replaced if necessary.

The range can consist of both newly manufactured parts, original parts and NOS parts.
Where new tiles or suitable replacement tiles are not available , used tiles in good, fully usable condition may also be available. These are carefully checked before sale.
Washers are used to control axial play between rotating parts. Some washers in the Jetaway box are selective , meaning they come in different thicknesses to allow for proper adjustment of the axial play.
When renovating, it is therefore important to:
measure the axial play in accordance with original GM workshop manuals
choose tiles with the correct thickness based on measured values
Incorrect axial play can lead to increased wear and deterioration of function over time.
Stocks should always be checked for:
wear and tear
discord
damage to roller tracks or surfaces
Sprag components are used for one-way functions in the Jetaway box and should be carefully inspected during refurbishment.
In original GM manuals and parts catalogs, these components may be referred to in different ways.
