Positions D, 3 and L - 2nd gear

WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.

Primary shaft (P1, P2):

The input shaft rotates clockwise and C1 connects the input shaft together with the rear planetary train ring gear so that it also rotates clockwise at the input shaft speed.

B2, F1 and B1 prevent the sun gear shaft from rotating in any direction. F2 is in freewheel mode. The inner planetary gears rotate clockwise and at the same time move clockwise around the sun gear shaft. The planetary gear carrier and the driving intermediate gear rotate clockwise as a unit.

Secondary shaft (P3):

The power flow here is the same as in position D for 1st gear. As the driving intermediate gear rotates clockwise, the driven intermediate gear and P3 ring gear will be driven counter-clockwise. The planetary gears rotate counterclockwise.

B4 and F3 lock the sun gear so that it cannot rotate in any direction. The planetary gears rotate counter-clockwise and at the same time move counter-clockwise around the sun gear. The planetary gear carrier and the driving final drive gear rotate counter-clockwise as a unit.

The driven final drive gear rotates clockwise at lower speed than the driven intermediate gear.
