Stall Speed Test Procedure

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2002 Toyota Tundra, 2002 Toyota Tacoma, 2002 Toyota Sequoia, 2002 Toyota 4Runner, and 2001 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: DO NOT maintain stall speed RPM for more than 5 seconds. Allow engine to idle for one minute between tests to allow fluid to cool.
  1. Operate engine and transmission at normal operating temperature. Connect scan tool to DLC3, located under instrument panel. Apply parking brake and block front wheels.
  2. On 4WD models, place transfer case in "H2" position. On all models, start engine, apply brake pedal and place transmission in "D". Accelerate engine to full throttle and note maximum RPM obtained. Repeat test in "R". Compare reading obtained to specification. See STALL SPEED SPECIFICATIONS  table. If stall speed is not to specification, check for the following conditions:
    • If stall speed is the same for both ranges but lower than specification, engine output may be insufficient or stator one-way clutch may not be operating properly.
    • Stall speed exceeding specification in "D" range may be caused by a slipping forward clutch, defective No. 2 or overdrive one-way clutch, low main line pressure or transfer case direct clutch slipping.
    • Stall speed exceeding specification in "R" range may be caused by a low main line pressure, direct clutch slipping, 1st and reverse brake slipping, overdrive one-way clutch defective or transfer case direct clutch slipping.
    • Stall speed exceeding specification in both ranges may be caused by a low main line pressure, improper fluid level or defective overdrive one-way clutch.
