Overview
Manufacturer
FordReference
FordReference
Four power shift gears arranged in two synchronized ratio groups (1-4 and 5-8). Two synchronized ranges (low/high) and right-hand shuttle. Clutch must be used to shift range or move between the lower (1-4) and higher (5-8) gear ratio groups. Push-button power shifting between the four gears in a ratio group. Push-button de-clutching on the shuttle lever allow shifting without the foot clutch. The 16 power shift was standard on the 5640 SLE.Reference
