Hi there,

 

Seems the trans has problem and you can go into self diagnostic to see if you can retrieve any codes.

 

SELF-DIAGNOSTIC PROCEDURE
NOTE: Perform self-diagnosis with engine at normal operating temperature.

 

1. Ensure engine is at normal operating temperature. Turn ignition switch to OFF position. Set transmission mode switch to AUTO position, overdrive switch to ON position, and selector lever to "P" position. Turn ignition switch to ON position, but DO NOT start engine. POWER indicator light should come on for 2 seconds.

 

2. Turn ignition switch to OFF position and move selector lever to "D" position. Set overdrive switch to OFF position. Turn ignition switch to ON position, but DO NOT start engine. Move selector lever to "2" position. Set overdrive switch to ON position, move selector lever to "1" position, and set overdrive switch to OFF position.

 

3. Depress accelerator pedal to floor and release pedal. Record POWER indicator light flashes and we shall see what the diagnostics shows. Long and short flashes should be recorded accordingly.

I tried all you said and I got the following results:

 

-O/D light blinks like a Camera Flash light for ten times and only 5th number of flash is little bit longer than other 9. Also, all ten times flashing repeat again and again untill I start off the ignition.

 

Thanks

Hi there,

SHIFT SOLENOID "B" TEST

 

1. Check resistance between solenoid assembly connector terminal No. 1 (Yellow wire) and ground. Resistance should be 20-30 ohms. If resistance is not as specified, replace solenoid.

2. With ignition switch in OFF position, disconnect solenoid harness connector in engine compartment. Check resistance between solenoid harness connector terminal No. 7 and ground. Resistance should be 20-30 ohms. If resistance is not as specified, repair circuit as necessary.

3. Disconnect ATCU connector. Check resistance between terminal No. 7 of sensor harness connector and ATCU terminal No. 7. Resistance should be approximately zero ohms. If resistance is not as specified, repair circuit as necessary.
