2003 Acura TL Transmission Problem

I have a 2003 Acura TL-S the car runs great with a perfect engine
Last april I took the car to Acura for servicing and I was told that there was a recall on transmission, something has to to with the 2nd gear and they put some kind of inject on it.
Anyway, last night while I was trying to park I did a reverse and than a D5 and the car wont move, it did eventually move, but it took its time, when ever I turned the car on and off, the transmission works perfectly.
In other words, when I start the car, the car works perfectly, but if I drive it for a mile or two and try to park, do a reverse and a d5, I start giving me problems other than that no problems.
NB: note that, if I turn the car off and on, the issue is gone

Any help would be greatly appreciated.
