Hi Paul! Thank you for choosing ExpertHelp.com. First may I know if you are still on the freeway or are you park safely now? And also when dis this problem started? And are you seeing error code flashing on your dash? When your ready, please type your responses on this page and then click on the Blue Send Response button to post your response. I will be standing by for your response.

Thank you for your response. The first thing I will do is to check the transmission fluid, You’ll need to check it while the truck is running and the transmission is warm, usually a 1 - 2 mile drive is enough to warm it. If the fluid is low, top it off. Likewise if it’s overfilled, drain some out. If the fluid is brown or smells burnt, it needs to be changed. If the fluid is foamy and thick, then there's engine coolant or water in your transmission fluid. Second you need to have it scan using a OBD 2 scanner to make sure to get the correct error code so you can determine what is the correct parts need to be replace. But what I can suggest you and first thing I will do is that I will change the transmission fluid. When was the last time you change your transmission fluid?

I see. Can you try to remove the negative connection on the battery for about 5 minutes and then connect it back again and have it run for 15 minutes. Check if the wrech icon will appear again. And then if it will not appear drive the truck 2 blocks and se if there is any changes. I will be standing by for your updates.

Then wrench light is actually for needs maintenance to be done on your truck like need to check the engine and transmission fluids but since you told me everything is still good I think its just needs a reset. Advise me what will be the result. I will be standing by.

I see. We check everything that it will possibly causing this issue. But what I can suggest you is to have it change the transmission fluid first and see if there is any changes after that. But if you will still be getting the same issue what I can recommend you is to have the transmission check and try the following option below.

• Drop the transmission pan and valve body and check  for any debris and clogs.
• Check the Transmission pressure. Listed below what cause the result of the pressure of the transmission and needs to be check.
  

  Test Results	Possible Source
  High pressure at idle	Wiring harness EPC solenoid  Main regulator valve
  Low at idle	Low transmission fluid level Control Bodies Tranmission pump leaking fluid Damaged transmission gaskets Leaking transmission case Stuck main regultor valve
