Claims

[Scope of utility model registration request]

In an automatic transmission in which a clutch is used to connect and disconnect an engine and a transmission, detection means for detecting engine speed, vehicle speed, and accelerator opening are provided, and shift changes are performed based on detection signals from these detection means. What is claimed is: 1. An automatic transmission system comprising: a determination circuit that determines whether or not the transmission speed is determined; and a control device which controls and synchronizes the engine rotational speed, clutch engagement/disengagement, and transmission based on the output signal from the determination circuit.
