STALL TESTS
During these tests the engine runs at full throttle and works against the torque converter, the hydraulic system, or
both the torque converter and the hydraulic system. The results of these tests will show if the cause of poor
performance is one or more of the following: (1) engine, (2) torque converter or transmission, and (3) hydraulic
system.
