    Arrow NAG1 Slipping on Shifts while spraying N2O

    Hey Guys,

    I recently installed nitrous on my 2006 300c AWD with the 5.7 hemi. Spraying a 50shot through the shifts the trans has a hard time shifting, once enough to put it in limp mode. Ran a 12.3@108 though!

    How can i firm up the shifts/ raise the line pressure? I have the predator tuner on increased pressure already but it is not enough.

    Thanks
    Jeff

    My 07 Magnum R/T that I did heads, cam and procharger on has the same problem. I ran a 12.1@116 going into limp mode. I ordered a dings racing valve body and custom tcm. I will be testing them out this weekend.

    If you have cooked the frictions and steels, the transmission is on a one-way path that can not be recovered from. The glazing is now the new coefficient of friction within the clutch mechanisms.

    So this should really be your first decision; how many and what kind of parts are you going to throw at it...to simply delay (slightly - maybe) ending up requiring a replacement...

    agree 100%


    also if it has high miles on the stock trans , it’s time for either a refresh or a new trans and converter imo

    trans is on its way out... in my eyes you have 2 options;
    Buy a mopar reman/have yours rebuilt and talk to ding's about a valvebody + tuning.
    OR
    Buy a performance based transmission from SHR or Paramount and throw it in.

    Personally, i'd go with option #1

    Before driving it too much more, change the filter. It has a fine mesh fabric inside that will plug up! Change it and break the old filter apart and take a look inside.

    I have a 06 300 SRT8 on a bigger shot it has whats called flare on the 2 to 3 shift if i lower the shot its fine...i was told a performance Valve body will do the trick so i bought a Dings VB getting it installed in about 2 weeks so ill see how it does...

    The trans has 175k miles. All gears still shift great at the strip when off the spray. The car is a hooptie so it's not worth putting a built trans in it. If it goes it's getting a junkyard unit.
    I ordered a Tranzformer and a window switch for the nitrous. I'll raise the shift firmness to the max and shut off nitrous right before the shift; and see what it'll hold.

    With the window switch set up to turn off the spray 100 rpm before the shift, it shifts perfect even with a 150 shot at the dragstrip!
    We will see how reliable it is! Ran a 12.03@113.5mph.

    Exactly what I did on my Challenger when it had the stock trans. 100 rpm before the shift, worked beautifully.
    Nice time as well!

    I got my dings valvebody and tune in, no more flare at all. Shifts 1000000% better. Zero issues
