    2004 5.4L V8 Trans slipping in 2nd Gear

    how many miles on it? I've heard lots of stories of people who mistakenly paid for a tranny overhaul when all it really needed was the gear position sensor. Apparently that sensor goes bad and causes havoc, and of course the tranny shops purposely don't diagnose it, they just tell you it needs...

    need a new muffler

    On mine I removed the two rear cats, and the giant single inlet/outlet muffler. I Then ran dual 2.5" pipes from the converters into a dual inlet/single 3" outlet muffler. I'm using a Spintech brand muffler, the same brand used by most circle track racers whenever they're forced to race in a town...

    Poll about 5.4l V8 and mileage

    2003 5.4L, 154,000 miles I get approximately 19 mpg with cruise set at 70. I hardly ever go faster than that. If I see a tractor trailer then I draft behind him, and even at speeds above 75 mph I'll easily get over 24 mpg while drafting. If I back away from the draft at that speed, the mpg...

    Loud Whine going into 3rd and 4th gear

    The factory service manual says to test the TCC, bring it to 50 mph and lightly tap the brake pedal while holding the gas pedal. You will see a 200 rpm rise when the tcc disengages.... it's not doing that at all, and I'm really sure it was doing that a few months ago. I hooked up my SCT tuner...

    Loud Whine going into 3rd and 4th gear

    Mine only does it after driving a continous 3 hour stretch on the highway. The sound is a high pitch squeal. After you let it cool off a few hours the sound goes away. I'm overfull by half a quart, I don't think it's nearly enough to cause a real problem. The other problem I found is that even...

    Loud Whine going into 3rd and 4th gear

    No it doesn't actually, it sounds like I may be about to spend some big money that I can't afford right now.

    Loud Whine going into 3rd and 4th gear

    Just drove my 03 exp to the Keys, first trip driving that far (5 hours). Both ways, after 3 hours the tranny started making an extremely loud whine as it shifts into 3rd and OD. Seems to be shifting softer into OD now too. It's like a squeal, squeak, whine sound that lasts for 1 second during...

    No Slipping With OD Off

    Not to side track the thread or anything but- I have an intermittent COP dying only when I first startup at 6:30 in the morning, it works fine after about 20 seconds, however I'm getting a constant slip like feeling and kick in and out of OD at low speeds. It would make sense that the big rpm...

    Overdrive issues??

    So far it's still a huge difference, much better. However since doing my exhaust system the truck still has a problem kicking in and out of overdrive at speeds below 50. It's extremely sensitive to throttle changes and dumps out of overdrive if you sneeze. Once above 50 it's back to normal, but...

    Overdrive issues??

    UPDATE: I tried adding a bottle of "Trans X" transmission cleaner for the hell of it. After a few miles it worked and the truck's been shifting right into overdrive, even at 40 mph. The bottle of additive says it's designed to clean off varnish and gum deposits to free up valves. The only...

    03 Stock sub wiring info

    Looking for the color codes for the stock amp/sub on my 2003. Are the factory sub amplifier inputs line level or high level?

    Installed SCT SF3 on our Expedition.

    Not to compete with Mike, but to speak for other SCT tuners- Mine's NOT a canned tune file and I gained both MPG AND power. I only picked up about 1-2 mpg using the performance tune, but the power difference is insane. 0-60 went from 10.5 to 8.2. Also towing my boat is effortless, you don't...

    Overdrive issues??

    I'm thinking it's either a computer issue, or a sticky valve in the transmission. The computer issue would possibly be a TPS not giving the right reading? Not likely though.

    Overdrive issues??

    For the last month it seems that it doesn't want to shift into overdrive unless I get around 45-50, and then have to let off the gas. When it shifts it's a nice solid bump into gear, definitely not slipping. Anyone else have this problem? It was doing this before I changed the fluid and...

    What kind of engine oil everyone uses?

    I been using Valvoline Maxlife- it cured my oil consumption problem. Besides that I'm an Amsoil fanatic.... M1 isn't bad either. Amsoil locally is unaffordable- they charge $14 a quart!!!! WTF

    rear a/c blows warm, front works great, not blend door.

    Mine was blowing two choices...warm or hot. So I replaced the rear expansion valve ($20 on ebay) and it fixed the problem.

    The Correct trans filter from Autozone

    Autozone's computer system is incorrect. I purchased a filter for my 2003 2 wheel drive, 5.4L according to their computer system. Took mine apart, stranded at home with no ride.....and realize that I have the wrong filter. Then when I get a ride to Autozone I have to argue with some simple...

    Installed my NEW $99 Bull Bar

    Sorry just realized you had this question. I went to Home Depot and bought wire mesh that's used for putting stucco onto the sides of homes. It was $7 for a 4ft by 8 ft piece.

    Factory Subwoofer information 2003 EB

    I've got a stock 03' Eddie Bauer edition, with factory subwoofer. It's got tons of bass (for me) but needs to be a little louder, hit a little harder. Where's the stock amplifier? I'd like to replace it with one a little stronger and probably replace the sub with a better one in stock location.

    Real or Fake?

    That's a pretty old scam that I can't believe is still allowed on ebay. There's just no way possible to get 20 hp out of tricking the computer to dump out more fuel than normal. You'll be lucky if the check engine light doesn't come on. Usually the tuners get a little bit more hp by slightly...

    Tuner question????

    I love the laptop application for SCT. It's a little tricky getting it set up and then being able to read it going down the road, but it does a LOT of sensor monitoring. It's useful for checking O2 sensor readings side by side on an oscilliscope looking graph, you can see if one is slower to...

    Pics of my new engine

    On your lightning SC swaps, how many miles were on those engines? Just thinking your excessive blow by may have been from high mileage. My stock 5.4 had a consumption problem when I bought it with 137,000 miles on it, like a quart every 500 miles. I ran valvoline max life oil which is known for...

    Tune-up info

    Mine has the 5.4 liter so I can't help, I don't know where it's located or the part #. I don't know of any engine that does not have a PCV valve. On mine it's located on top of the right valve cover and it has a steel pipe wrapped around it, the steel pipe has antifreeze in it. Apparently during...
