A punched tape program is being used to control power shift transmission test stands operating as single or multiple units. Any desired shift sequence (sequence or skip shifting) is availabel with no concern for rate of shift lever movement, accuracy of detent postions, etc. Transmission shifting is accomplished by using electric solenoid valves to control the shift valves. Test unit design and construction, the test controller, test cycle design, test results, laboratory-field correlation, engine, costs, and test stand deficiences are covered. This system provides test flexibility, rapid data acquisition, engine life data, and minimum equipment investment.
