Its function is for oil to force it towards the front or bell housing side of the trans, applying the low/reverse clutches. This allows reverse when applied simultaneously with the direct (high gear) clutches, and allows manual low gear when applied with the forward clutches. Manual low gear creates engine braking on deceleration. The low/reverse clutches do not apply in automatic range 1st gear. The low sprag (low roller clutch actually) causes first gear when only the forward clutches are applied. |
In the rare application that does not need reverse or low gear engine braking, the low piston and low clutches can be deleted and the feed holes in the case blocked. | In the rare application that does not need reverse or low gear engine braking, the low piston and low clutches can be deleted and the feed holes in the case blocked. | ||
