Hey everybody, I have a 08 f250 superduty with a automatic in her.( I call my truck her, I hope that does not offend anybody )Every so often but not all the time it seems like the transmission does not feel like it shifts like it should. Sometimes when you are going from 60kms to 80kms it kind of feels like it studders between 3rd and forth and then every once in awhile if you are driving at 50kms and give her a little shot it feels like she shifts down into a lower gear quicker then she should almost like it is spinning on ice, again this only happens once in awhile. I have her in the performance mode of my superchip and I have also installed a Banks cold air intake on her.One other note I have had the transmission flushed and new fluid put back in her. Please let me hear what you think....Thanks
