Ford 7.3L Power Stroke (1999-2003) :: Transmission Stays In OD Off Position Until Hit 55 Mph
I've read a few things on the 4R100 and have a question.
My transmission stays in the OD off position until I hit 55 mph no matter the tune I am using and then will up shift to OD. It turns back off once I drop below 30 mph.
I was told when I bought the truck that it was a factory tow package. Is this a thing?
I would like an option to turn it off when I'm not towing or climbing a hill if I can.
Any way to modify it with a switch?
Ford 7.3L Power Stroke (1999-2003) :: 2000 - High Beams Won't Stay On
First time driving my 'new' 2000 7.3 Ex and the high beams won't stay on for more than a minute or two. Playing with the switch in the driveway, they came on after a minute of not being run, but after throwing the switch a few more times, they wouldn't come on again. The indicator light corresponds with the high beam function. I'm thinking a relay is going bad? The switch is brand new and the bulbs are definitely working. Also, I did not get an owners manual with the truck, and the fuse diagram I found online did not match the box at my left knee.

Ford catalog does not list the TPS for a 1999 7.3 Super Duty as a separate replaceable part which leads to replacing the whole throttle pedal assembly. I found this to be incorrect. If you have a throttle pedal assembly with separate TPS (separate 3 wire connector) and IVS (Idle Validation Switch 2 wire connector) just the TPS can be replaced.
This is a pic of my 99 with new TPS installed : [URL] .....
Without removing the whole assembly you only need to remove the 2 T25 screws and the connector to replace.
Since this part is listed for more then 20 Ford trucks I figured it would work in my 99 7.3. I bought a brand new TPS from Pete (F250_) that he could not use. He has a 2002 with one 5 wire connector. It works perfectly in my 99. Not sure if it will work in a 2000 or 2001 but if the TPS and IVS each have their own connector it should. Make a visual inspection to be sure.
Part DY-967 or F4SZ-9B989-AA - Potentiometer
I was going to go with a Dorman TPS but like PartsGuyED likes to say "OEM Baby". The OEM TPS through Ed is actually cheaper then the Dorman.
Side-by-side pic of the old and new TPS. Only the center rotating part is different but it fits and works just fine. It also has a better fit so there is less slop and almost immediate response.

By the way, the original TPS was working fine so I have no idea what the symptoms of a bad TPS are. Since it was available I replaced it to have a spare and to see if this one would work. Both Pete and I thought it would and we were right.
Ford 7.3L Power Stroke (1999-2003) :: F250 Hard To Start And Won't Stay Running
What's up power stroke fam. I have a 1999 F250 Super Duty 7.3 liter this is what happen, was leaving the job site the truck started just fine ran for about 3 city blocks stopped at a stop sign and it started to run ruff like it was out of fuel but had a half tank then poof it shut off. After towing the truck home and trying to start it I could hear a relay clicking very sporadic the service engine light came on then when off and the truck started and the exact same thing happened started running ruff and shut off. Where should I start other than taking it to the shop?

So finally got my truck running due to a fuel issue. Anyways been driving it for a week or two now, and I have a strange problem idk if it has been covered here or not.
Driving around tow etc if you come to a light or whatever and stop the rpms stay at 800rpm. Now if you shift it out of gear and back into drive the rpms settle back down around 650. Where is should be.
My guess is the torque converter is not disengaged all the way when it stuck at high rpm (800-900) for this situation. No cel, slippage, or crazy noises

Ford 7.3L Power Stroke (1999-2003) :: Individually Lighted Position Display For The Chip
So the idea has been kicked around before, but to my knowledge no one yet has done it on FTE. That is, a lighted display switch for our chips that only lights up the current position. Well, I've got it done!!
First some pics, then read below for how I did it. First pics are in the light, the next two are how it looks in positions 1 & 5 at night.
Now, for how I did it. First off, I started with one of the lighted displays from BCPD. Each number has an individual LED behind it, so I could wire up each one for the position it's in.
The back of all the chips have 7 wires attached to it. One is black, it's in the middle, and it is a common ground to the chip. The other 6 wires are all position grounds. The switch works by grounding one wire to the black wire for the position you are in. If you look at where the wires plug into the chips, the one farthest away from the black is position #1, and they count up sequentially from there toward the black wire.
First thing is to unplug the the selector **** cord from the chip before doing any work. I acutally ordered a spare switch from Jody, just in case I screwed up something (which I didn't), I wouldn't be without my chip.
I took the black rubber off the back of the switch to access the soldered connections. I soldered the ground for each LED on the display to the appropriate pole with the wire connected to it on the back of the display. I had some CAT 5 ethernet cable lying around, and I used the wires inside of it for the ground from the switch to the display. You can use a DVM or continuity tester to check for continuity between the black wire and each position to veryify which wire belongs to what position. I ran the extra wires out the bottom of the rubber cover, along with the original wires.
For power, I only wanted the lights to be on at night. So, I tapped into the wire for the gauge lights, put a 1 amp inline fuse (old glass type fuse), and connected all the hot wires of the LED's so they are a common hot. The LEDs already had resistors wired into them, so I didn't need to add any more.
The fit for everything where I put it was a little tight, but I eventually got it to fit, as you can see. And all the lights do work, and show up quite well at night. The display works by having a common hot to all LED's and grounding the one that for the position it's in, completing the circuit and lighting the LED.
Some other ideas would be to wire up 6 different colored LED's to constant power and place them somewhere else, say in the A-Pillar, dash, or on the door to the inside of the mirror. So, you'd have a different color LED for each position. It's not limited to using the BCPD display, that's just what I already had. The creativity is up to you on how you'd choose to light things up for each position.
Finally, I did talk to Jody about doing this and any negative effects it would have on the chip. He said there would be none, since you're just pulling a ground from it. Also, if you use an LED, they are by design only allowing current to flow in one direction, since they are diode's already. But, to be on the safe side, I used the 1 amp fuse on the power wire. You won't need any bigger than that as the LED's don't draw very much power at all.
Ford 7.3L Power Stroke (1999-2003) :: F250 - Clutch Pedal Goes 1/3 Of Way Down - Drops To Floor And Stay?
I just bought a 99 f250 super duty with 6 speed and it has clutch problem the clutch pedal goes about 1/3 of way down then drops to the floor and stays. I pulled slave cylinder and it has just as much resistance as a new one. my other thought was a spring internally in transmission. any other thoughts or do I just need to replace the clutch?

I tow a 44' Goose neck racing trailer on a regular basis so I dont want autozone crap rotors that are going to warp in a few thousand miles. I was on rockauto.com, they have Wagner, Bendix, Motocraft, Powerstop, etc etc. I thought maybe those Powerstop drilled and slotted looked interesting, but I dont know much about them.

View 3 RepliesFord 7.3L Power Stroke (1999-2003) :: 4R100 Trans Shifts Hard When In Any Position Other Than Stock
I just bought a 2002 F250 7.3 4x4 auto. It had a TS 6 position tuner installed. In stock mode, I got about 11 mpg. I wasn't too impressed. I found that when I left it in 75hp mode, my mileage went up to 21. I drive easy and try to keep shifts at or below 2,000 rpm. The problem is that, when in any position other than stock, my transmission shifts HARD.
My question is: what's going on here? Does the TS change the transmission shifts? Or is the extra bump in power enough to stress the tranny? Based on the factory gauge, the transmission is not running hot. The fluid is nice and pink with no odors or metal shavings. I'd hate to prematurely kill my transmission, but nearly doubling my fuel mileage is hard to pass up.
Ford 7.3L Power Stroke (1999-2003) :: Dash Lights Not Coming On When Position The Switch Into 4x4 High Or Low
When I position the switch into 4x4 High or 4x4 Low the dash lights do not come on. Also, I have a vacuum leak at both hubs.
I tested the vacuum lines from the ESOF solenoid (or whatever it's called, the box on the fender where the vacuum lines originate) and I don't have any leaks in the lines. I put the Mighty Vac straight to the back of the hubs and I definitely have leaks at both hubs.
So, why am I not getting the light on the dash, and why do I have leaks at the hubs? FWIW, I replaced both wheel hub assemblies in March, and everything worked fine at that time. I'm hoping the yellow o-rings are still good. Is there a chance I lost torque on the four bolts behind the hubs causing a failed seal? Is there a seal on the outside of the hubs that could've failed?

Well a few days ago I pulled up to a gas station on my way to work for some coffee and since I leave for work before 6:30 AM my headlights were on. Well only the running lights were working. Well I shrug it off and later that night I come to the realization that both headlights weren't working. I tried the high beams and they do work. I also pulled both bulbs and both the filaments on each bulb seemed to be intact. What could cause this? I checked fuses 9 and 11 under the hood and they were both fine. I'm kinda at a loss right now.

So I have noticed that my Batteries have been low each time my truck sits. Also my headlights have been dimming/brightening with acceleration. So I thought my Batteries were going bad. So I did some tests, I let my truck sit over night and tested the Batteries before starting they both were around 11 volts. @ idle no load 12.3, with load 11.7. @ 1500 RPM 14volts. With this I went to autozone and had the Batteries tested and the guy said that they are good but need to be charged and that the alternator was not charging right causing the low Batteries. The Batteries are about 3 years old. So now Im not sure what to do.

Ford F-150 - 1997-2003 :: 2002 V8 - Dashboard Gauges Always Stay In The Same Position
I have an F 150 2002 Trition V-8. I always thought I knew how to read an instrument panel on a vehicle but after being put down by my Ford, I have to rethink this knowledge.
I have noticed over the past 4 years that my volt meter guage on the instrument panel always stayed in the same place whether the motor was running or just the key in the on position. I noticed that a little battery icon kept coming on and going out yesterday. I read the owner's manual and it said something like this indicates your battery is not taking a charge correctly. Well why has the guage not told me anything. Well the alternator has quit but yet and still the guage is still showing me all is well.
I ask a Ford dealer service dept. about this and they do not have a clue. All they tell me is people do not pay attention to the guage but when the light comes on they need. They also said the gauge would work when everything shuts down, but man! I don't need it to work then. I know it's broken when that happens. It quits running.
What is the purpose of the gauge sitting there all shiny and pretty if it is not going to say anything other than "HEY MAN! I am just here looking pretty and taking up space".
I have looked at other trucks and they do the same thing. Nothing .. What is going on with this gauge which undoubtedly does nothing?

Ford Super Duty (1999-2016) :: 2014 - Headlights Stay On?
This is my first post on this forum. I have a 2014 F350 standard fleet truck. The headlights are not day time running lights. The headlight switch is the basic off/parking light/on. The headlights come on as soon as you start the
truck. This just started happening about a month ago. When you shut off the truck the headlights stay on for ten minutes. I scanned the truck with a snap on modis. I got into the lighting module and the "command on" is on. The modis would not give me the option to turn it off. Short of taking the truck out of service for a day to go to the dealer. Is there any other fix I can do?
