Default A4 acting up.

I drove my C5 last night for the first time in over a year.New motor and built A4 that worked perfect just before I put it away.Trans already had 2000 miles on it and was untouched during mod process except for restalled convertor.Everything worked fine for about 100 miles and then trans would not shift out of 2nd.No leaking fluid underneath.Even shifting manually it won't come out of second and I had to take it up to 4000 RPM to get it to shift out of first.One thing I did notice is the speedo had stopped working.Does a 4L60E need a speed reading to shift?
I love this sport.
Thanks in advance.

AIR, your A4 needs 3 perimeters to function correctly engine RPM, TPS, and road speed.
Without all 3 of these it will malfunction.

Yes -- the shift tables have 2 parameters---Throttle position and MPH --Thats only for part throttle operation---BUT at WOT it uses RPM and MPH---- Try to disconnect your battery for 1-2 hours and let the ECM unload--- try it again--

Well my speed sensor was plugged in and the sensor does work.Looking for an electrical problem now.Hopefully it is not a problem in the trans.
