My car has been acting funny the past week. The Overdrive light would blink incessantly for about 10 secs and then go away sometimes when I start my car. Plus I experience a slight jerk (sometimes not so slight) when I accelerate and my rpm reaches about 2-3k.

Any thoughts on what's wrong with my car? Any solutions?

this is from the FAQ. that's why everyone says to read the faq's and stickies:


This Transmission Control Module self-diagnostic procedure information was abstracted from the '99 Maxima factory service manual. It applies to '98 and '99 models. Plain Jane (my '99 GXE) is a 5-speed so this procedure has not been personally tested.

1) Move the shift selector to Park.
Start the engine and let it run until it reaches normal operating temperature.

2) Turn the ignition switch OFF.

3) Wait at least five seconds.

4) Turn the ignition switch ON but do not start the engine.

5) The O/D OFF indicator lamp should turn on for about two seconds.
If it does not, stop here because the rest of this procedure won't work.

6) Turn the ignition switch OFF.

7) Turn the ignition switch to ACC.

8) Move the shift selector from Park to Drive.

9) Turn the ignition switch ON but do not start the engine.

10) Press and hold the O/D OFF button.
Continue to press the O/D OFF button until step 13 (below).
The O/D OFF indicator lamp should be on.
If not, stop here because the rest of this procedure won't work.

11) Turn the ignition switch OFF.

12) Turn the ignition switch ON but do not start the engine.

13) Release the OD/OFF button.
The O/D OFF indicator lamp will be off.

14) Wait two seconds.

15) Move the shift selector from Drive to 2.

16) Press and release the O/D OFF button.
The O/D OFF indicator lamp will be on.

17) Press and hold the O/D OFF button.
Continue to press the O/D OFF button until step 19 (below).
The O/D OFF indicator lamp should be off.

18) Move the shift selector from 2 to 1.

19) Release the OD/OFF button.

20) Press and release the O/D OFF button.
The O/D OFF indicator lamp will be on.

21) Press and release the O/D OFF button.
The O/D OFF indicator lamp will be off.

22) Press and hold the O/D OFF button.
Continue to press the O/D OFF button until step 24 (below).
The O/D OFF indicator lamp should be on.

23) Press the gas pedal to the floor and then release it.

24) Release the OD/OFF button.

25) The O/D OFF indicator lamp will exhibit a sequence of flashes.
The first flash is distinctly longer than the others.
Subsequent flashes are very short and these are called Judgement
Flickers.
Count those JFs and watch for one which is twice as long as the others.

Interpreting Judgement Flickers...

JF0) All JFs are short.
All circuits which can be confirmed by this self-diagnosis procedure are okay.

JF1) The 1st JF is longer than the others.
The Revolution Sensor is short-circuited or disconnected.

JF2) The 2nd JF is longer than the others.
The Vehicle Speed Sensor is short-circuited or disconnected.

JF3) The 3rd JF is longer than the others.
The Throttle Position Sensor is short-circuited or disconnected.

JF4) The 4th JF is longer than the others.
The Shift Solenoid A circuit is short-circuited or disconnected.

JF5) The 5th JF is longer than the others.
The Shift Solenoid B circuit is short-circuited or disconnected.

JF6) The 6th JF is longer than the others.
The Overrun Clutch Solenoid Valve circuit is short-circuited or disconnected.

JF7) The 7th JF is longer than the others.
The Torque Converter Solenoid Valve circuit is short-circuited or disconnected.

JF8) The 8th JF is longer than the others.
The ATF Temperature Sensor is disconnected or the TCM power source circuit is damaged.

JF9) The 9th JF is longer than the others.
The Engine Speed circuit is short-circuited or disconnected.

JF10) The 10th JF is longer than the others.
The Line Pressure Solenoid Valve circuit is short-circuited or disconnected.


If the O/D OFF indicator lamp exhibits a series of long flashes, these
are not Judgement Flickers.
This condition indicates a problem with the battery.
The battery may ...
- be discharged
- have been disconnected for a long time
- be connected with reversed polarity

If the O/D OFF indicator lamp stays on continuously, this is not a Judgement Flicker. This condition indicates any of these conditions ...
- PNP switch is disconnected
- O/D OFF button circuit is damaged
- Throttle Position Sensor circuit is disconnected
- Transmission Control Unit is damaged
