    Question Hard Downshift, lb7 dsp 5

    I have a 2004 LB7, I installed a DSP 5 switch, a knowledgeable friend of mine installed several custom EFILive tunes: 1 = Stock, 2 = Loop, 3 = Smoke, 4 = Power Tune 1 and 5 = Power Tune 2. After installing the tunes the truck down-shifts really hard and clunks even harder 4-3, 3-2, 2-1, We have adjusted everything we can think of to smooth it out with no luck! Any ideas, suggestions or help is much appreciated.

    Thanks

    Hello!
    If you made full flash, trans is relearning for a while, I think

    Agreed, give the ally a chance to relearn. go easy on it the gradually ramp up the throttle each time you go from 0 to cruising speed.
