TORQUE CONVERTER STALL SPEED TEST

CAUTIONDO NOT perform torque converter stall speed test for more than 5 seconds or transmission may be damaged. Transmission must be cooled between tests by placing shift lever in "N" position and operating engine at 1200 RPM for at least one minute.
  1. Apply parking brake. Block all wheels. Connect tachometer and start engine. Warm engine to normal operating temperature. Ensure transmission fluid level is correct.
  2. Fully depress brake pedal. Place shift lever in "D" position. Fully depress accelerator for no more than 5 seconds and note highest engine speed. This is the torque converter stall speed.
  3. Place shift lever in "N" position. Operate engine at 1200 RPM for at least one minute to cool transmission. Repeat test procedure with shift lever in "3", "2", "L" and "R" positions.
  4. Ensure torque converter stall speed is within specification. See «TORQUE CONVERTER STALL SPEED SPECIFICATIONS»(ref-151076-S29632278752002121100000) table. If torque converter stall speed is not within specification, an internal torque converter or transmission failure exists.
