weird thing post dyno tune

Post by Enano »

on a dynojet
5.7L Hemi Charger. modded
BaseLine (cutouts closed) 343.24 HP, 355.19 TQ
After Tune (cutouts closed) 366.12 HP, 371.2 TQ
After Tune (cutouts open) 372.86 HP, 377.64 TQ



Upon driving home from the dyno. after getting off the congested expressway and taking the service road i decided to play aruond a little. This problem arose and is repeatable
Only at WOT when using auto stick from slow/stop in 1st gear, (i think i tried it from 2nd to 3rd and it worked, dont remember. if i tried it, it worked,) I normally will use autostick to downshift and then let the computer do the upshift, i tried letting the computer shift and personally shifting a bit early between 5 and 5.5k. Upon trying this once it climbed up in the rpm it goes to shift but instead shifts into neutral and doesnt put power down, i can rev it put no power to the wheels, pulled over to the side of the road, tried putting it in nuetral, back into drive, it didnt put power down, just revved, stayed locked in neutral, tried going to all things, P,R,N,D just stayed in neutral. the digital display showed it moving (although it wouldnt show the gear when trying to use autostick) between PRND but nothing was happening, you couldnt feal the tranny switching. By shutting off the car i was able to get it to reset and work properly. It shifts fine under WOT in D.
No CEL.
its like its about to slam into second gear then decides not to.
