I just recieved my 7.7 in a trade and looks hardly used, motor is real tight. But it does'nt shift at all. From a dead git its alittle sluggish and them slowly starts to come on like freight train. My thought is that its stuck in second gear. Would the adjustments have anything to do with this? The motor is running on the rich side and is definatly geting a little to hot, which tells me its laboring to get the truck moving. If anyone can help giving the stock shift engagement settings I would really be thankfull.
