I asked this question before with no answer but now it's really starting to **** me off. When I floor my car from 30mph it doesn't downshift to 1st more than half the time. Then the other night I floored it at 34mph!! and it downshifted to first. I thought it was only supposed to downshift under 32mph so I think something really has to be messed up. Any ideas would be very helpful. Thanks.
