    Exclamation 2000 Sierra staring and trans. problems

    Hi, I have a 2000 GMC sierra 1500 5.3L 4wd, I was driving down the road and hit a bump and all the gauges went to 0 except the voltage and oil pressure. The transmission also kicked out of overdrive and when I stopped the trans. would not downshift. When I tried to start it back up, it would not crank but I could hear the starter relay in the dash click but not on the starter. I have checked the ground to the engine, chassis and frame which all had ground. The odometer is also not working!! I just put a new battery in it about a week ago too! Please help!

    I tested battery and even put the old battery back in and still the same problem. I checked the alternator and it is charging fine. I think the problem is somewhere under the dash but not sure where at. Just wondering if anyone had the same problem who knew where the problem is actually at. This is not a spam post!!

    Well then its either the forum could have done something or something, but it was there I clicked on it chassis and frame and it went to ebay I swear, now its not showing up. I have noticed there has been spam post like this it look real but then nobody responds. I dunno maybe it was a glitch.

    it may be worth looking at the ignition switch. not sure on the year, but this was a common problem with chevy.

    Subject: MIL On, Transmission Stuck in Second or Third Gear, IPC Inoperative, DTCs P0740,P0753,P0758,P0785,P0787,P0973,P0976,P1860,P2 761,P2764 and/or P2769 Set (Verify and Repair Source of Voltage Loss #01-07-30-002E - (09/23/2005)

    2005-2006 Saab 9-7X

    with 4L60-E, 4L65-E, 4L80-E or 4L85-E Automatic Transmission (RPOs M30, M32, M33, MT1, MN8)




    --------------------------------------------------------------------------------

    This bulletin is being revised to update model years, add additional models and add additional diagnostic information. Please discard Corporate Bulletin Number 01-07-30-002D (Section 07 -- Transmission/Transaxle).


    --------------------------------------------------------------------------------

    Condition
    Some customers may comment on one or more of the following conditions:

    � The Malfunction Indicator Lamp (MIL) is ON.

    � The transmission is defaulted to second gear(4L80/85-E).

    � The transmission is defaulted to third gear (4L60/65-E).

    � The instrument cluster is inoperative.

    Upon investigation, one or all of the diagnostic trouble codes (DTCs) P0740, P0753, P0758, P0785, P0787, P0973, P0976, P1860, P2761, P2764 and P2769 may be set depending on the vehicle.

    Cause
    The most likely cause of this condition may be a loss of voltage to the transmission solenoid power supply circuit.

    This condition may also be the result of an incorrect installation of an aftermarket electronic device such as a remote starter or alarm system.

    Correction
    Important: If the vehicle is equipped with an aftermarket electronic device and the DTCs are being set when the device is being used, verify that the appropriate fuse is being supplied battery voltage during operation. If voltage is not present at this fuse, these DTCs will be set due to lack of voltage at the solenoids. This condition is most likely to occur with an incorrectly installed remote starting system. If this is the case, refer the customer to the installer of the system for corrections. ANY REPAIRS DUE TO AFTERMARKET INSTALLATION OF ACCESSORIES IS A NON-WARRANTABLE ITEM.

    With the ignition switch in the RUN position, test for battery voltage at the circuit fuse in the transmission solenoid power supply circuit. Refer to the appropriate SI Document for the transmission solenoid power supply circuit information.
    If battery voltage is present at the fuse, inspect the ignition voltage circuit between the fuse and the transmission for possible opens.
    If battery voltage is not present at the fuse, test for continuity between the fuse and the ignition switch. If NO continuity is between the fuse and the ignition switch, repair the open in that circuit.
    If you have continuity between the fuse and the ignition switch, the most likely cause is the ignition switch. Replace the ignition switch using the appropriate Ignition Switch Replacement procedure in SI. Refer to group number 2.188 of the parts catalog for part description and usage of the ignition switch.

    I was thinking about that too! I had it narrowed down between the starter relay in the dash, the ignition switch, or a loose power or ground under the dash. Since I already have the dash torn apart i'll do alittle more searching for a broken wire but I think i'm gunna replace the ignition switch also. Thanks for the help mudseeker!

    I just changed the ignition/starter switch and i am still have the same problem.. I check the fuse panel and found that the IGN 0 fuse doesnt have any power on either side of the post even after taking the fuse out and checking for power on the post.. Any suggestions on where to start looking now? I'm thinking maybe a relay somewhere but not sure which one!
