Engine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. The input shaft fixed first gear is in constant mesh with the output shaft loose first gear, which is in constant mesh with the reverse shaft loose gear/synchro hub assembly. As reverse gear is selected, the reverse fork moves the reverse synchronizer towards the reverse shaft fixed gear. The synchronizer sleeve engages the reverse gear clutch teeth, locking the shaft into one rotating assembly. The reverse shaft fixed gear is in constant mesh with the input shaft third gear. The input shaft third gear, which is in constant mesh with the output shaft third gear, acts as an idler, which reverses output shaft direction, changing the output direction of the transaxle. See Fig 1.
