Stall Test
Stall TestingThe stall test is an effective method of testing clutch and band holding ability, torque converter one-way clutch operation, and engine performance. A stall test should only be performed as a last resort because of the high fluid temperature it generates and the excessive load it places on the engine and transaxle.
CAUTION:
a. Transaxle and engine fluid levels should always be checked and fluid added as needed.
b. Run engine at 1,200 rpm to attain proper warm-up.
c. During test, never hold throttle wide-open for more than 5 seconds.
d. Do not test more than two gear ranges without driving vehicle to cool off engine and transaxle.
STALL TEST PROCEDURE
1. Set parking brake and block wheels.
2. Install a tachometer where it can be seen by driver during test.
3. Start engine and place selector lever in "D" range.
4. Apply foot brake and accelerate to wide-open throttle.
5. Quickly note the engine stall speed and immediately release throttle.
Stall revolution:
GA16i engine models
2,350 - 2,650 rpm
6. Shift selector lever to "N".
7. Cool off A.T.F.
8. Perform stall tests in the same manner as in steps 3 through 7 with selector lever in "1" and "R", respectively.
9. If stall revolution is out of specified value, perform troubleshooting following Stall Test Analysis.
