The Engine Light stays on most of the time. I changed the trans. And it still doesn't want to shift right. I've been told that it could be the Ignition Switch. Could that be possibly my problem? I've changed the fluid and filter 3 times so far and nothing helps. Do you have any suggestions? Any help would be GREAT! Thank You, Stanley

The Service Engine Soon Light stays on. The Code that it shows is 0758. I don't know what to do. As I said before, People keep telling me that it's in the Ignition Switch. But I hate to keep wasteing my money getting parts that don't help. Do you guys have any idea of what my truck needs beside replaced it with a new one.

Stanley,
Based on the code, you have a bad shift solenoid. It could even be the wiring going to it. They are not hard to replace, but they are hard to diagnose. There are two of them, so if you replace one, you may want to do both to make sure you get the right one. They are not hard to replace. You did the trans service, they are on the valve body in the trans. Wiring will be going to them.

Let me know if this helps. Also, I would think a bad ignition switch would cause more than one code to come up for you. If the computer is saying the solenoid, that is where I would start.

You're welcome. I hope it takes care of everything. Make sure to check the wiring for continunity to make sure there are no internally broken wires, and don't forget to let me know how it goes.
