Like i siad, flashing means something electrically went wrong the previous time you started the car.

Right. I was clarifying my original post for biking4life.

Is it possible to pull a code even if the light is not currently on?

Like the ECU some codes are stored some are not.

i am tired but some place in this link

http://www.endwrench.com/archive/sysdrive.html

it says how the TCU works, if it holds codes, and how to retrieve them (without a reader).

if no one else answers in more detail ill respond....

nap time

Blu and i went 4 wheeling yesterday so both a little tired.

cool. Looks like a lot of good information. I'm going to delve right in. I need to go take my car off pavement sometime. The last time I did, it was fun.

I went to Advance Auto Parts today and had them try to pull any codes and nothing came through.

Ok one more time...

it is NOT the obdII connector. PERIOD.

To repeat myself
"The light will flash if during the last operation cycl, there was an electrical fault in the tranny. This flashing is meant to catch your attention, and tell you you need to pull the codes. You can either search here for the method to pull the codes (it's NOT the OBDII plug) or get it to a dealer."

That has NOTHING to do with the transmission. The tranny has its own computer, its own test connector, and its own codes.

Read this then tell us what code you get.

I don't know if this helps or not....on my 97 Outback the A/T light blinked sixteen times in a row.....each and every time I started the car....my husband has a computer cd repair manual.....it said that if there was a problem, the light would blink 16 times each time you started your car.....the blinking would stop or reset itself after something like 40 car starts if there really wasn't a 'problem'....indeed after the 40 starts....the light quit the 16 flashes on start up....this phenomenon happened twice to me....both times after I had run it thru the carwash....don't know if it was the carwash or coincidence...but both times the light quit it's 16 blinks.....I guess if the light never cancelled or reset itself, my husband would have investigated it....but since it happened after the carwash, we just waited it out.

Alright. I took one of the grounding wires and stuck it into the #5 slot on the connector. Nothing happened. I turned the car to 'ACC' and still nothing. Then, I turned the car on and still nothing.

Either it's fine or I'm dumb.

If there is a problem it will come back. The TCU is a bit more sophisticated then the ECU. The TCU can tell if a solenoid is stuck open, closed, or was sluggish in its response. If its not there, its not there.

Do you think that by testing the resistance in the system between certain plugs (as shown in diagmanual.pdf) I can find any problems in their infancy?
