Shifting quick with X street....

[rjwareagle]

I have been running my x street for over a year now. today, i was heading down the on ramp onto I75 and noticed that from 3rd gear to overdrive? it shifted real quick. Almost like it tried to miss it. temps were fine actually a little low. is this the sign of trans problems? This has happened a few time before but nothing serious. Maybe its the tune or Im not staying in it long enough... any ideas?

tried it today... and it seemed fine.. but why just some of the time?

Mine will do this sometimes, too... it all depends on the grade, accelerator pedal position, and the vehicle speed. For example, mine will go from 3rd to 6th locked very quickly if I'm going down hill at light throttle input from say 30 mph to 50 mph.
