What is the specified stall speed (stall revolution) in this test?

The stall revolution is specified as 2,800 - 3,100 rpm.

How long can you hold wide-open throttle during a stall test?

Never hold the throttle wide-open for more than 5 seconds during the test.

What warm-up is required before performing the stall test?

Run the engine at 1,200 rpm to attain proper warm-up, and check transaxle and engine fluid levels, adding fluid as needed.

How many gear ranges can be stall-tested before cooling the vehicle?

Do not test more than two gear ranges without driving the vehicle to cool off the engine and transaxle.

In which gear ranges is the stall test performed?

The test is first performed in "D" range, then repeated in the same manner with the select lever in "1" and "R" respectively, shifting to "N" and cooling the transaxle fluid between tests.

This is page AT-65 from an automatic transaxle (AT) service manual section titled "Trouble-Shooting and Diagnoses," covering the Stall Testing procedure. It explains that a stall test checks clutch and band holding ability, torque converter one-way clutch operation, and engine performance, and warns that it should only be performed as a last resort due to high fluid temperatures and heavy loads on the engine and transaxle. Cautions include checking transaxle and engine fluid levels, warming the engine at 1,200 rpm, never holding wide-open throttle more than 5 seconds, and not testing more than two gear ranges without driving the vehicle to cool the fluids. The eight-step procedure includes setting the parking brake and blocking the wheels, installing a visible tachometer, starting the engine in "D", applying the foot brake and accelerating to wide-open throttle, noting the stall speed (specified as 2,800–3,100 rpm), shifting to "N", cooling the transaxle fluid, and repeating the test in "1" and "R" ranges. Two cartoon-style illustrations (SAT597 and SAT598) depict the test setup and the "less than 5 seconds" throttle rule.
