    Anyone have any info on a 2006 5.9 litre cummins 3500 4x4 automatic transmission, that is throwing code P2121?
    While driving the accelerator occasionally loses action. Believe this has been called dead pedal, and also is not shifting properly...

      Replace the Accelerator Pedal Position Sensor. Probability here is greater than 90%.

      What kind of fluid is leaking. Antifreeze, power steering or transmission fluid. There are small rubber lines that connect to the radiator. Those are cooling lines for transmission fluid. It is common for the rubber lines to swell up and start leaking. If your transmission fluid level is low it will cause slipping. Tighten the cooler line hose clamps or replace the hoses and clamps. Make sure to check the trans fluid level and top off if needed. The trans dipstick will specify which fluid type and procedure to use. Or check your owners manual.

    Car stalls and shuts off when I come to a stop
    Randomly when I am stopped at a red light or stop sign, my car will either jerk forward while my foot is on the brake, or it will completely shut off. It restarts with no issues and will drive for days/weeks until it decides to do it again.

      You may have a loose gas cap. Sometimes that triggers the check engine light. If not go to Autozone for a free diagnosis, they can pull the code up for you.

      I'm sorry this was for a different question.
      Could be either a vacuum leak, or it could be the IAC valve (idle air control). Do the RPM's fluctuate?

      Is there a check engine light? If not could be a bad fuel pump. fuel filter, or a vacuum leak.

    What is wrong if driving on highway & warning light comes on and my speed suddenly goes from 70 to 45.
    half hour later it is fine and light is out.

      No clue. Plug in a code reader and see what fault code set in memory.

    What else can leak besides pinion seal and rear cover on the rear end?
    I know my pinion seal is leaking. I added some gear oil and I'm not sure if there is a leak on one side where the axle exits and goes to the wheels. Can you have a leak there? If so is it a major thing? Thanks
     
    • HouseCallAuto

      Yes you can have a bad axle seal there and leak oil into the brakes. major thing, well if this is presented to the professional shop the job will *likely* also consist of a major brake job at the same time. Could have a bill of more than 3 to 4 hundred depending on what parts. New drums would put you at near 1000 if included with wheel cylinders and shoes and hardware.

    I need a rear pinion seal (you guys diagnosed it for me). Supposed to be an easy job,but what about the squash ring?
    Mechanic made me worry, said you can only squash it once.

      Here is tip from a mechanic doing this for 38 years and this is what I do in this situation. Put a white mark on the pinion nut that is indexed to the pinion. Sometimes I even use my high speed die grinder to make a tiny grind mark that hits the nut and shaft ever so slightly and will not cause any problem. The white out sometimes rubs off while handling the nut and the grind mark does not go away. After replacing the seal, put back the pinion nut and tighten the nut back to the same place as before and then add about 1/32" tighter. No more than that. I did not say 1/32th of a turn on the nut. I mean make the reference marks pass each other by 1/32" . When threading the nut back on, I am assuming that you will know by feel of the driveshaft flange when you have reached the final pinion nut position. You can also count how many turns it takes for the pinion nut to come off and then that number will be the same when you reassemble. The 1/32" still applies. If you were to accidentally go more than 1/32" do not back up. I hope I have not confused you. The crush collar can crush tighter but once crushed it cannot rebound, hence why I want you to go to the original position exactly and then go 1/32" past. It will be fine. The crush collar is what sets the inner and outer pinion bearings preload. The idea here is to simply go past the original mating marks by the smallest amount possible which is why I give you the smallest measurement that you can still see on a tape measure index. If it went 1/16" it would not cause an issue but I want you to use a smaller number as a target because at this point even the slightest turn of the nut increases pinion bearing preload exponentially. If you want to confirm that you have not overtightened it, then before you take it apart, use an inch pounds torque wrench that can measure inch pounds like down low like 0 to 50 inch pounds. Measure how many inch pounds of torque it takes to turn the flange at the pinion nut. After you reassemble it should not be more than 10% tighter.

      Thanks for the detailed answer. Sounds like the important thing is marking the pinion nut. I will be having a professional do the job, either the dealer or my mechanic.

      Don't assume that they will do it correct. This is a big gray area among mechanics from what I have seen. Some of them just tighten up the pinion nut way too tight and then a few weeks later (more or less) the rear blows up.
