Won't shift 1-st - 2nd at WOT
 

OK

This happened befor and I fixed it with changing the VSS. My speedo is jumping around at WOT, part throttle, the car drives great. The speedo started jumping to to long after I got the car(about a month or 2 back in Novemeber 12 i got it ). I got the sensor replaced and the car shifted fine for a while (2-3 weeks) and now it is back to messing up ......its like it goes to shift into 2nd, and the RPMs drop down...then kicks out like it was in 1st and free revs sorta. I havent hit the rev limiter, as soon as it happens I am off the throttle. It feels like it goes to shift into 2nd and registers a lower speed and tries to go back to 1st. Some helop PLEASE :cry:

any one?
