Car won't shift
 

Went to the track yesterday, and my car wont shift on juice. It use to on the 100 shot but yesterday on the 150 it wont shift. I moved my window switch to shut off at all the way down to even 4thousand rpm's and it still wouldnt shift. I have heard that alot of cars dont shift with nitrous but it use to so i'm kind of concerned. Whats up?

Do you know if the pcm comanded the shift , In not sure if you have access to a scanner or tuner that can read the data stream but that would be the first thing to do , determin if the shift was comanded , If not it would need to be tuned for that setup , If it was comanded it could be a transmission issue

thats it, I had the same problem but thats exactly what happened, like it was too fast for the pcm to shift, the actual transmission is fine. So deff a tune TA4EVR is what we have to get :bang:

thanks guys. like a full out tune on the dyno and stuff or just a power programmer or something or what

Well obviously the dyno tune would be best but . someone with a power programer who knows just what to tweak could probably get you going with a little trial and error

I guess i'll just plan on saving for a tune
