Check engine light when on today on my way to work. After sitting off for a few hours while I was at work I turned him on to head home. As soon as I left driving and took off from the first light the light came back on again. Did the paper clip test to try to get a code from it. Can you guys help identify the problem.

F= Single Flash
p= pause

Check engine light blinks like this: F F p F F
also the O/D OFF blinks like this: F F F F F F p F F F --> then does: F F F F F F p F F F F

any clue to these patterns?

22 ......................... Open Or Short Circuit In Engine Coolant Temperature Sensor Signal......Thats for the CEL

63 .............................. Defective No. 2 Solenoid
64 ............................ Defective Lock-Up Solenoid...........Those are for the OD Light

ECT ECU Codes
1) Turn ignition on. DO NOT start engine. Depress OD switch
on shift lever to ON position.
NOTE: Codes can only be retrieved with OD switch on. If OD switch
is off, OD OFF light will be on continuously and will not
blink the code.
2) Install jumper wire between terminals TE1 and E1 of DLC1
or DLC2 connector. See Figs. 8-10.
3) Note number of flashes from OD OFF light on instrument
panel. If normal system operation exists, OD OFF light will flash once
every .25 second. See Fig. 11.
4) If system is operating correctly and no code exists, turn
ignition off and remove jumper wire. Perform MANUAL SHIFTING TEST
under TRANSMISSION SHIFT TESTING to determine if problem is a
electrical or mechanical transmission problem. Check system by the
symptom. See appropriate symptom under SYMPTOM TROUBLE SHOOTING.
5) If code exists, OD OFF light will blink once every .5
second. Number of blinks equals first digit of code. After a pause of
1.5 seconds, second digit will be displayed. See Fig. 11.
6) If more than one code exists, next code will be displayed
after pause of 2.5 seconds. See Fig. 11. Smallest number code will
display first and system will progress to largest code. Codes will be
repeated.
7) Once code is obtained, determine probable cause and
symptom. See CODE IDENTIFICATION table. For diagnosis and repair of
codes, see DIAGNOSTIC TESTING. Turn ignition off and remove jumper
wire.

Ok the top one I can fix regarding the sensor.
Now regarding:
63 .............................. Defective No. 2 Solenoid
64 ............................ Defective Lock-Up Solenoid...........Those are for the OD Light

^^^ Does that mean my tranny is on it's way out? Is it an expensive fix for the two solenoids?

As far as the lock up, never had to mess with it, but there is a sticky on here regarding solenoid replacement.
