    No power when pressing accelerator
    when i give it gas, there is no power to pull the vehicle and it revs high and you have to ease off the accelerator to make it shift into the next higher gear. and the check engine light is flashing.

      Did you check the engine with a scan tool already? I suspect that the air intake is restricted or the fuel system is clogged. Check the condition of your air filter if blocked; replace it if necessary. Replace the fuel filter and inspect the fuel lines if there's a bent. Have a pressure test also for fuel pump to determine if the fuel pump is giving sufficient pressure. A failing fuel pressure regulator or throttle position sensor can also cause this problem. Have it all verified by a scan tool.

      Did you check the brake fluid already? You may have a brake fluid leak that's why you have a lose brake pressure. Inspect the fluid and the brake fluid lines for possible leakage. Add fluid or replace a damage hose if needed. Can the engine still able to idle? If yes, possible that your neutral safety switch is unable to disengage because you need to press the brake pedal hard or the pressure is needed to disengage the safety switch. In order to verify this, you need to scan the vehicle even without the check engine light is on.

      Did you check the condition of transmission fluid already, maybe it is low or the fluid is contaminated? It could also be that this is cause by clogged transmission filter. Check the fluid and change if necessary and then observe the changes. Post a query again if in case the problem persists with additional inputs.

    The truck will not go into reverse, drive, but will turn over just fine.
    120,000 miles. This is the first time it has happened. I was at a complete stop. Started driving at 10 mph and heard a snap (not loud) and the truck went into neutral by itself. The engine was running okay, but the truck would not reverse or go forward. Could ...

      sounds like the transmission, something has let go internally, have it checked out by a transmission specialist, but you will probably have to replace or rebuild the transmission

    Do you have a video on how to change a transmmion.
      11/9/2010 MOONSTER_TOOLZ
      If you can browse the videos of AutoMD, you will find out there's is no transmission replacement video posted; possibly because it is not a DIY job or they haven't posted it yet. But for sure everyone can expect more videos to come specially those DIY jobs.

    Trans noise in 4th gear only
      11/8/2010 MOONSTER_TOOLZ
      Check the condition of your transmission fluid if low or contaminated. Add oil or change it if necessary. If this does not resolve the issue, I am afraid this more likely an internal problem. A shift solenoid for fourth gear is damaged. I recommend bringing it to a transmission shop for overhaul and if possibly repairing it before more damage afflicts your transmission.

      Someone with a full function scanner that is capable to read the transfer case fault codes has to read the fault codes. if you don't know the codes you cannot fix the vehicle.

    Noise coming from rear differential
    had transmission and rear end rebuilt roaring nise still there
    • HouseCallAuto
      11/6/2010 HouseCallAuto
      Someone missed something in the repair process. the carrier bearings that the differential rotates on can fail and give a roaring noise. A pinion bearing or an axle bearing. It is one of those three things that someone skipped checking maybe. or, someone overtightened the pinion nut when the rear was assembled and now the pinion bearings new or old are destroyed, (seen that a few times in the last 35 years)

      Or when they rebuilt it they didn't allign the pinion gear to the ring gear properly.

      Yes your fear is right, the side bearings have too much slack and that is why you hear the sound on turning, take it to a dff shop and they can change the side bearings other wise the sound will become more and more.
