First off, I don't know if this is tranny, motor, or suspension related. But between the speeds of about 5 and 10mpg I get a shuttering/shacking in the front end of my truck. It is enough to feel/see in the steering wheel and pedals. It is a little more noticeable on deceleration but is also very noticeable on acceleration. I fear that it is my tranny, which I know needs to be rebuillt to handle my tune, but I am just puttiung off the inevitable. I also recently installed some HD cognito tie rods and notice that they make contact with my sway bar under full lock to lock turns. Anyone experience anything like this?
