Is my tranny dying?
So I got back from a week vacation and now it seems like my transmission is slipping. When I am in gear [D] and slow down to a near stop, sometimes when I try to accel. again, it seems like it is in neutral. The RPM will move correctly and then it just engauges into gear like as if it was a manual and you dropped the clutch too fast. I added some transmission fluid (Castrol Dextron III?) through the dipstick and it seems like it gotten better after the 5 minute test drive (up hill, down hill, stops, etc.) but after it sat for a few hours, it starts to act up again. Should I add more fluid? I checked for codes and it was 0505. Hope this is a simple fix.... 
PS... the car was driven when I was gone on vacation so it wouldn't just sit there for over the week.

isn't there a way to directly run auto-transmission diagnostics? I might be thinking of something else though. Also, you might try having the fluid flushed and new fluid put in. The gear oil doesn't last forever.

I added in a quart and it didn't seem to show up on the dipstick. Perhaps I am that low on fluid? Also, I was wondering if I could had in some type of additive to help stop the leak. Any recommendations?
PS... the problem seems to be appearing when it is trying to downshift. Couple times it wouldn't engauge when I am slowing down to a light and it turns green. It also didn't downshift correctly when I took a turn and tried to accelerate. But these problems last about 1-2 seconds before it goes in gear again.

I did this diagnostic but I forgot which code appeared when I came back in to check. It was either code 9 or 10? But then again, when I tried to check it again, it wouldn't show me the same code again and it was all short flashes (no error). I will check it again after I drive home and let you guys know.

1. Start engine and warm to normal operating temp with O/D off.
2. Turn ignition swith to off postiton wait 5 sec.
3. Turn ignition switch to the ACC position.
4. Put O/D to ON.
5. Move shifter to P, turn ignition on but don't start engine.
6. The OD light should come on for about 2 secs.
a. if light does not come on somthing is wrong with the trans. computer.
b. if light comes on proceed to no 7.
7. Turn ignigton key to off.
8. Turn ignition key to on, don't start engnie.
9. Move shift lever to D, trun ignition to off.
10. Put O/D switch to off position.
11. Turn ignition off.
12. Put O/D to off, turn ignition ON wait 2sec and move shifter to the 2 position.
13. Put O/D to on, move shifter to 1 position.
14. Put O/D to off, depress accelerator all the way to floor and release.
15. The computer is now in output mode and will start displaying the codes.
There’s one long flash that signifies the start of the sequence. Following
should be 10 short flashes. Then it
repeats.
Remember the first long flash indcates the start of the sequence followed by
10.
All 10 flashes the same = No error codes read at this time
1st flash longer than others = Revolution sensor is shorted or disconnected.
2nd flash longer than others = Speed sensor circuit is shorted or disconnected.
3rd flash longer than others = Throttle sensor circuit is shorted or
disconnected.
4th flash longer than others = Shift solenoid “A” circuit is shorted or
disconnected
5th flash longer than others = Shift solenoid “B” circuit is shorted or
disconnected
6th flash longer than others = Overrun clutch solenoid circuit is shorted or
disconnected
7th flash longer than others = Lock-up solenoid circuit is shorted or
disconnected
8th flash longer than others = Fluid temperature sensor is disconnected or A/T
control unit power source
circuit is damaged.
9th flash longer than others = Engine revolution signal circuit is shorted or
disconnected
10th flash longer than others = Line pressure solenoid circuit is shorted or
disconnected
All the same with no long start flash = Battery low, been disconnected, or
control unit has just been
reconnected.
