Stall Speed Test: Procedure

Operate engine and transmission at normal operating temperature. Connect tachometer to vehicle and ensure it is visible to driver. Apply parking brake and block front wheels.
CAUTION: DO NOT maintain stall speed RPM for more than 5 seconds. If performing more than one stall speed test, operate engine at about 1000 RPM in Neutral for 2 minutes to cool transmission fluid before performing next test.
Start engine, apply brakes and place transmission in "D" position. Depress accelerator to full throttle and note maximum RPM obtained. Repeat test in "R" position. Stall speed should be 2100-2400 RPM.
