Well, like i said in my other post ive got a 96 351 5.8l that is having shifting problems. I have replaced the TPS sensor and it is still having the same problem. It has a very hard shift when it does shift or it will reb the engine real high and it wont shift at all untill i let off the gas a little bit and then get back into it. :doh0715: The auto part stores cannot hook there reader up to it and get the code even though it is a 96. I have noticed under the hood there is a connector that says EEC TEST at the end of it. Im just really hoping to get to the bottom of this problem. Thank all yall in advanced for helping me out.
