Does this transmission have the k1 spring problem that causes the 2-3 shift issue? Anybody know?

I cleaned the MAF last night and it smoothed out my idle (curious to see if it helps with my gas MPG) but did nothing for the shifting issue. Adjusted the modulator on the side of the trannie and while that firmed up my shift I still have second gear holding before it shifts.
