    I have a 2004 chevy Silverado 4.8, the problem is the picture of the engine is showing in the left side of the dash, but the service engine soon light isn’t coming on. I have checked for codes but no codes are coming up, I checked the owner’s manual and it says that it’s a misfire. The engine light was flashing when coming home and shut off motor in the drive way. Left it sit for 3 weeks, started it up no lights came on the dash whatsoever. I have changed the crank sensor, electronic throttle component on the front on top. Afterwards it kept doing the same thing.. I pulled it out of the garage and started it up to warm up for 5 mins it stop running. I started it back up and again 5 mins later stop running. I tried a third time and it wouldn’t run at all. Left it to sit overnight tried it the morning and it fired right up and kept running. Need help, stump. Im really afraid to drive anywhere, because I don't want to be stranded in zero degree weather.

    I am the original owner of a 2003 Ford Expedition Eddie Bauer with 140,000 miles. Two days ago, I noticed that the transmission attempted to shift to 3rd gear... but would not engage (it dropped into Neutral). When I added gas, the RPM revved up to 4500 RPM when the transmission finally dropped back into 2nd Gear. It drives and shifts smoothly in reverse, 1st, and 2nd gears with no abnormalities noted. With O/D OFF selected or "2" selected on the shift selector, the car drives in 1st and 2nd gears only... up to 60 MPH at 4500 RPM. I replaced the Transmission Fluid and Filter... all looked clean with only minor micro-dust size particles in the fluid and a nice vibrant red color. Does anyone know what else can I do before sending it to a Transmission Shop for a costly rebuild or replacement???

    You're pretty much at the point where you'd need diagnostics to go any further--that is, pressure testing and using a scan tool to activate and test solenoids, etc. At 140K, internal wear is certainly possible and slippage is never a good sign.

    I have a 2007 Expedition with 85k miles. When I accelerate up through 2nd and 3rd gear there is a vibration as if I am running over warning rumble strips. It only does this when I maintain a constant speed at about 25 to 40 mph. If I hard accelerate through the gears and get up in speed the vibration doesn't happen at all. After I get to 40 mph and higher there is no vibration. Does anybody have any ideas?

    Get a scan of the truck's computer and let us know what codes appear.

    There are wired going from under the hood down to the trans check them very carefully for any melted wires.alot of times they are and that will cause the problem.mostly where they go by the header on the passenger side.

    Good morning, I have a 2000 expedition EB. The problem I’m having trouble diagnosing the issue. It doesn’t happen all that often it only happens after I’ve been off-road, going through some puddles, and if it’s raining hard. The problem is that when driving on the freeway I’m running at really high rpms the transmission doesn’t shift into the higher gears. It will occasionally shift into higher gears then downshift to lower gears (1st or 2nd). I will turn the vehicle off let it sit for a little while and then start driving again and it will run normal shifting normally for a few minutes then downshift to the lower gears again. When I turn the car off for about an hour and drive it again it runs fine. Anybody has similar issues or have any ideas of what this could be?

    Have you had the TCM scanned for codes?
  • Expo123Expo123 Member Posts: 4
    Yes and there are no codes

    Aside from checking fluid level and doing a transmission service the next step might be a test at a transmission specialist. There are so many possibilities here. Loss of internal pressure is one. Any idea of the color and smell of the fluid? I presume your off-roading is not gung-ho recreational rock climbing, etc. ?

    It's also possible that more than one professional scan tool should be applied here.

    I had the transmission fluid changed recently because of the issue and it did not fix it. Fluid levels are good, smell is good as well I also brought it to aamco they ran their test no codes came up and their technician came out checked and smelled the fluid they suggested cleaning the connecters and boots making sure all the wires are not bad. No rock climbing here!

    Well that's not a bad suggestion, to clean all wiring and plug-ins to the transmission. What may be required here is to drop the pan and test all the solenoids.
  • Expo123Expo123 Member Posts: 4
    I think I’m going to clean the wires and connections if it comes to that then I’ll take a look at the solenoids

    It does sounds like some kind of internal pressure problem---but you know, at that high mileage it could just be internal wear---seals get hard, etc.
