coder reader/scanner code clear function is handy in that it does not clear the NAM ECU/PCM computer memory learned engine/tranny unique performance parameters based upon driving style, hill/flat terrain, fuel quality, etc
from Ford Service CD manual
How to Clear the Continuous Memory
NOTE:
Do not disconnect battery to clear Continuous Memory. This will erase the Keep Alive Memory (KAM) information which may cause a driveability concern.
1. Run the Key On Engine Off Self-Test.
2. When the DTC's begin to be displayed, deactivate Self-Test:
-- STAR Tester: Unlatching the center button (up position).
B-- All others: Remove the jumper wire from between Self-Test Input (STI) connector and the Signal Return Pin of the DLC.
-- Scan Tool: Pushing the STOP button.
3. Continuous Memory will be erased in the PCM.
B for all of us DIYers
pull the neg. - batt. leads clears not only the stored fault codes but also the NAM memory, returning the ECU/PCM to factory default programming which may cause start and run problems until relearned= abt 20 miles of varied driving...

If you have OBD-II aero, you need code reader for SAE Standard. There are K-L line OBD-II readers, but they dont work on aero.... Well, now I see often universal readers based on ELM 327 chip, they read all the standards (ISO K-line, ISO L-line, SAE (ford and GM) and CAN), but Aero needs no special program, universal programs, like ScanPro do it well.
If you have OBD-I aero, you need no tool.

There is a black box with a white connector hanging under the dash, right below the steering wheel.
I don't see much behind the battery. What am I looking for behind the battery ? I assume I was looking for some sort of tail to hook to. Everything is all strapped down.

Here's what I found. First 539. Turn off the A/C dork. 
Then I get 212. What does that mean ?
With no codes for my tranny issue. Which one of the connectors on the drivers side of the tranny is the shift solenoid ?
