STALL TEST

Stall Test Procedure:

The Stall Test Procedure is used to check for clutch or band slippage and for proper torque converter operation. Engine coolant and transmission fluid must be at proper levels and at operating temperature. Make sure Throttle Valve (TV) linkage is set properly. Service and parking brakes must be firmly set.

CAUTION: While performing this test procedure, Do Not hold throttle open for more than five seconds at a time.

1. Mark specified stall speed, as shown in the Stall Test Procedure, on tachometer and connect to engine. Position tachometer so it can be read from driver's seat
2. In each driving range, hold accelerator to floor for five seconds or less to let engine reach full RPM. Record results and let engine run at fast idle between each test to cool fluid.

CAUTION: If needle goes beyond specified RPM, some component is slipping and accelerator must be released immediately.

3. Refer to the Stall Test Procedure chart for corrective action.
