I have the cd. I did what you said about accelerator pedal and you were right. It appears to work fine.I took some pictures of the tests. I am getting no codes and eratic shifting.it seems like torque converter lock up all the time. i can send what every pics you need just tell me and I will take pics of the screen .As i drive the od is flashing after 2nd gear,it drift .in and out of gears.I does shift in to overdrive.

 

It turned out to be the instrument cluster had a short in the speedometer! I need to get it rebuilt. Any body you can recommend?

 

Just get a PSOM from a junkyard truck. If you find a truck that had the same size tires as yours, you won't even need to calibrate it.

 

I have one from a junkyard but the mileage is 375000 truck runs fine. my original odometer reads. 121,000. So i want to get my original repaired. So if I ever sell it has the correct numbers.
