A test system for testing torque converters, other fluid coupling devices, and the like, e.g., devices that couple engine power to driveline power. The test system drives the test device with a first hydraulic motor, which is itself driven by a first hydraulic pump. At the output of the test device, a second hydraulic pump absorbs the power from the test device, and drives a second hydraulic motor, which in turn drives the first hydraulic pump. A make-up motor is used to also drive the first hydraulic pump, to make up for any additional power desired for testing.

What is claimed is: 1. A system for testing a transmission coupling device, comprising: a make up motor; a first hydraulic pump driven by the make-up motor; a first hydraulic motor driven by the hydraulic pump, and connected to deliver mechanical power to the transmission coupling device; a second hydraulic pump, driven by mechanical power from the transmission coupling device; a second hydraulic motor driven by the hydraulic pump; wherein the make up motor and the second hydraulic motor are connected such that both the make-up motor and the second hydraulic motor drive the first hydraulic pump. 2. The system of claim 1, wherein the transmission coupling device is a torque converter. 3. The system of claim 1, wherein the first hydraulic pump is an axial piston pump. 4. The system of claim 1, wherein the first hydraulic motor is an axial piston motor. 5. The system of claim 1, wherein the second hydraulic pump is a bent-axis pump. 6. The system of claim 1, wherein the second hydraulic motor is a bent-axis motor. 7. The system of claim 1, wherein each pump and each motor is a variable speed device. 8. The system of claim 1, wherein the make-up motor is a constant speed motor. 9. The system of claim 1, further comprising a control system programmed to control operation of the transmission coupling device to a desired torque input or output. 10. A method of testing a transmission coupling device, comprising: using a make up motor to drive a first hydraulic pump; using the hydraulic pump to drive a first hydraulic motor; using the first hydraulic motor to deliver mechanical power to the transmission coupling device; using a second hydraulic pump to absorb mechanical power from the transmission coupling device, and to drive a second hydraulic motor; and using the second hydraulic motor to assist in driving the first hydraulic pump. 11. The method of claim 10, wherein the transmission coupling device is a torque converter. 12. The method of claim 10, wherein the transmission coupling device is a fluid coupler. 13. The method of claim 10, wherein the transmission coupling device is a gear transmission. 14. The method of claim 10, further comprising the step of determining a desired torque input and calculating the output required for the make-up motor, based on the power provided by the second hydraulic motor. 15. The method of claim 10, wherein each pump and each motor is a variable speed device. 16. The method of claim 10, wherein the make-up motor is a constant speed motor.
