So I started the truck to leave a few minuates ago and relized that the tach and speedometor did not work and the little orange indicator that shows you what gear you are in is not lit either and the tranny is "just not right" barring any physical problems with the tranny(which it is not......it all worked 25 min ago) #20 fuse (PRNDL) does not have any power at all and the fuse is fine . anyone have this problem before???????? please help!!!!!!!!!!

Turn it off and back on again and see if it clears?

+1. All my gauges quit working for 1 day once upon a time. The check your #%*((#'n O2 sensor engine light stayed on... but the next day the gauge cluster worked.

now the tranny does not shift right, I ve got 1st and 2nd, 3rd if I manually shift it but no overdrive and it will not down shift Im pretty sure this is an electrical issue I just dont know where to start

I had the same issue in an 02. I went and stated it and the gauges went blank, then a few seconds later came back on and then it shifted damn hard! It was the Ignition Switch, it went through 3 of them in 2 years, so I got rid of it. If it is throwing codes for transmission, then I would bet good money on an ignition switch. 1st time the SES light came on and I think 1 time it did not, but the codes were still there. Juts my .02.

There's a code for one reason or another that's putting the trans in default mode (default = max line, limited gears).

 

Get the codes read and proceed from there.

I had a similar problem on my 07 Silverado where nothing on the dash seemed to working. i took it to the dealship but they said they could not find any codes. After this happened for about the 4th time, I took it to the dealership while everything was "blank" and left the truck running while I went into the service center and had them come out and look at it/see it. After about an hour they told me something was not plugged in all the way in the dash. I guess I have to take them at their word because I have not had the problem since them.

Ive seen this before but forgot what triggered it.........but it works now after it sat for a few hours and has worked ever since...and just for good measure I did a fluid and filter change(it needed it anyway) thanks for the input guys
