One-way Clulch
The one-way clutch is positioned between the countershaft 1st gear and the park gea., with the park gear splined to the counter-
shatt, The 1st gear provides the outer race surface, and the park gear provides the inner race surface. The one-way clutch
locks up when power is transmitted from the mainshaft 1st gear to thetountershaft 1st gear. The lst clutch and gears
remain engaged in the 1st, 2nd. 3rd, and 4th gear ranges in the p!1, p! or L?l position.
However, the one-way clutch disengages when the 2nd, 3rd, or 4th clutches/gears are applied in the E, E or @ position.
This is because the increased rotational speed of the gears on the countershaft overrides the locking
"speed range" of the
one-way clutch. Thereafter, the one-way clutch free-wheels with the 1st clutch still engaged.
