Abstract
A device provides transmission control whereby when a vehicle starts from standing state, even if a driver releases a brake pedal, action of the brake is maintained compulsorily until the starting gear position is formed by connection of frictional elements in the automatic transmission. Therefore, this device prevents effectively a vehicle from slipping down, upon starting on an upwardly sloped road, without more action of the brake than is necessary and with good startability.
