Slippage means the clutches in your tranny are getting worn out.

OSS stands for Output Shaft Speed (from the engine) and TSS stands for Transmission Shaft Speed (from the tranny). Most of the time these two numbers will not match up. The only time where the two will match up is in 3rd gear with the torque converter locked. 3rd gear is a 1:1 ratio from the engine through the transmission but will not match up without the TC being locked. To make this happen you can just hit the O/D off button and drive fast enough for it to lock. The numbers may vary in the one's place but that is from slight lags in reading times.
