PROBLEM TO BE SOLVED: To provide a shift control device of an automatic transmission, capable of shifting a speed along driver's intention as much as possible without damaging an engine.SOLUTION: A TCU 50 included in the shift control device 1 of an automatic transmission includes: an over-rotation determination part 51 for determining whether or not an engine 10 over-rotates; a delay time setting part 52 for setting delay time until performing automatic upshift based on a selected shift mode and the oil temperature To of the engine 10 when it is determined that the engine 10 over-rotates; and a shift control unit 53 for executing the automatic upshift when the set delay time elapses. When a manual mode is selected, when the oil temperature To is equal to or higher than a predetermined value, the delay time setting part 52 set the delay time to zero, and when the oil temperature To is lower than the predetermined value, the delay time setting part 52 set the delay time longer as the oil temperature To is lower. |
