The embodiment of the application discloses an endurance test system of a two-gear shifting execution mechanism and method. The system comprises a rack baseplate and a support fixed on the rack baseplate, and a to-be-tested gear-shifting execution mechanism is arranged on the support. Two gear blocks are arranged at inner sides of a left end and a right end of the support, and a gear finger is located between two gear blocks; first limiting blocks, springs, second limiting blocks, fixed brackets and pressure adjusting devices are outwardly, orderly and symmetrically arranged at the left end and the right end of the support; each pressure adjusting devices apply different pressures on second limiting blocks; the pressure is applied to each gear block under the conduction of each spring andeach first limiting block, so that one gear block can simulate a working state of a shifting fork in an automatic transmission; and the gear finger is subject to the pressure from the gear block whenbeing moved to the locatio
