Ok guys i do have Transmission problems but need 2 put that aside for now. Today i was cheking the truck wich we just got a few days ago and the truck does not charge also no wait 2 start light and none of my gauges work need 2 fix that first before taking the transmission down any help please

 

Sounds like a dead PCM.

 

Agreed sounds like pcm is not linking up inside the cab if you have access to a obd scanner i bet there will be no communication with the pcm if so it may tell you whats up but it also could be a ground in the dash wiring harness i would also sheck your grounds and the fuses for blown fuses and corosion casuing no contactbut pcm very likely

 

Thanks Guys I will check and post results

 

Does the odometer say NOBUS by any chance?

 

No it just flashes all the time why

 

Because in my 2000 when the gauges quit workin it showed no bus it was a son of a gun to figure it out! Tired new gauge cluster nope tried new PCM nope finally the tech checked every pin in the connector and found a loose one and it was fixed. Something simple but it was a bitch and expensive to find. Good luck!

 

Try unplugging all the connectors on the PCM and plugging them back in. Do this a few times as it helps clean the contacts. Also check all your grounds. Also check the CPS on the front. If it doesn't send a signal to the PCM the PCM thinks the truck is off and will shut down the other stuff.

 

Try doing the cluster self diagnostic test, with the key off hold the odometer reset button in turn key on and continue to hold the button in for approx 10 seconds, see if any codes come up in the odometer window.

 

Sorry for taking solong 2 get back guys . I did the cluster self diagnostic test and these are the codes it gave me 920,921 and 999 any 1 know what they are Please Thank u
