+##Gear shift rules for AT Gearbox
+
+The gear shift rules for automatic gearboxes differ from AMT and MT.
+
+Gears are shifted sequentially:
+
+- 1C -> 1L -> 2L -> ...  (torque converter only in 1st gear)
+- 1C -> 2C -> 2L -> ...  (torque converter in 1st and 2nd gear)
+
+###Upshift rules
+
+- If engine speed in the next gear (see shift sequence) is above the upshift line AND
+- The engine can provide at least the same power as currently required (i.e., can keep the current acceleration)
+
+###Downshift
+
+- If the engien speed falls below engine's idle speed
+
+- Drivetrain in "Neutral" when either
+  - velocity < 5 km/h
+  - During deceleration phase when the torque converter is active and the engine speed would fall below idle speed
+
+###Shift parameters
+
+- Min. time between two consecutive gearshifts.

+##AT Gearbox Model
+
+Vecto supports both, AT gearboxes with serial torque converter and AT gearboxes with power split. Internally, both gearbox types are simulated using a power train architecture with the torque converter in series.
+
+!(Automatic transmission with torque converter in series)[pics/AT-S.png]
+
+!(Automatic transmission with parallel torque converter)[pics/AT-P.png]
+
+In the input data [Gearbox File](#gearbox-file-.vgbx) **only the mechanical gears need to be specified**. Depending on the gearbox type (AT-S or AT-P) Vecto adds the correct virtual 'torque converter gear'.
+
+For AT gearbox with serial torque converter, the torque converter uses the same ratio and mechanical losses as the first gear (and second, depending on the gear ratios), and adds the torque converter.
+
+For AT gearboxes using power split the torque converter characteristics already takes the transmission ratio and mechanical losses into account. Hence, Vecto sets the ratio for the mechanical gear to 1 without additional losses.
+
+The .vmod file for vehicles with AT gearboxes contains an additional column that indicates if the torque converter is locked or not.
