Automatic gear boxes are not working properly. Especially on raisings and when using "fast forward" keyboard control. (simulating the use of "Kickdown").

The gear box should let the engine use revelations up to the maximum revelations per second before shifting into a higher gear. The gear box should shift down into a lower gear if necessary when using "fast forward" (simulating the use of "Kickdown").

The gear box should use up maximum revelations before shifting up and shift down if necessary when trying to climb a hill.

Right now vehicles become slower steadily when climbing a hill and the gear box never shift down. This wrong behavior also leads to the wierd fact vehicles become the more quiet the larger the hill is they want to climb (because revelations/min are decreasing with lower speeds).
