Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 - Won't Shift To 3rd Gear - No Codes?
Apr 18, 2017
i bought a f250, i rebuilt the 7.3 after installing it the transmission isn't shifting correctly. Reverse perfect, 1st and shifts to 2nd great. wont go into 3rd. i replaced the 2 sensors on the transmission, i replaces the sensor on the 3rd member. the speedometer works but not correctly, i can unplug the sensor on the front of transmission and it shifts into 3rd. but when i plug it back it doesn't. no codes. could it be the ecm?

2001 F250 7.3 - warn manual hubs.. However, the wife has been driving the truck and I don't know how often she has cycled 4WD.
Basically if you choose 4WD hi it doesn't light up to indicate that it has engaged, if you drive for a couple of minutes slowly then eventually it drops in - not much use if you're already stuck. It will then select 4Lo. Coming out of 4Lo to 4Hi or 2WD is painfully slow - like 5-6 minutes before the dash light goes out for 2WD.
I was thinking maybe the electric motor for the transfer case - unless it is the transfer case dying.

I have a 2002 F250 Super Duty. Was driving it and it started to lose power and shut off. Then wouldn't start like out of fuel. No engine light no codes. Truck has 155k on it. So just because I replaced fuel pump. Truck runs but not right it's ruff no power kinda back fires in exhaust. I check wires and plugs under valve covers all seems ok. I ran truck and pulled each injector loose and engine would stumble. As in they are working. I replaced cps. Just because still the same. Then the truck started running right. But the truck runs but has knock but knock goes away and truck has full power. Yes oil is full and I change it regularly. The problem is off and on like electrical.

I noticed my '99 started getting difficult to get in gear & shift, within a coupe of days the peddle was barely off the floor before it would engage. A day later it started 'creeping' if started while in gear. Replaced the master/slave cylinders with no change.
Is a clutch replacement the next step? Just thought I would ask before throwing money at it, since the only other times I've had clutch issues there was slipping or it just plain exploded.

I need to replace the cable on my gear shift indicator. Of course you can't just replace the cable. I have even looked on you tube and not found anything. I don't know if maybe I am using the wrong search terms or not.

F350 2001.
Constantly throwing codes for both front wheel's ABS. Ohm'd out both sensors - same reading
Ohm'd out wires leading to sensors - same reading
Ohm'd out rear diff speed sensor against a new one - same reading.
Pulled front sensor's cleaned and put my fingers in the sensor hole. What should I be able to feel? I'm wondering if the previous owner put non ABS hubs on?

I purchased this unit, non running, was told the HPOP was bad, after going through the unit top to bottom, Im stumped, below is a list of items serviced and or replaced with OEM parts.
0. changed oil and oil filter
1. Terminator 500 Hpop
2. New ICP
3. New HPOP lines.
4. New starter and solenoid
5. Serviced Turbo (rebuilt with new parts and WW wheel)
6. Serviced Injectors (shimmed) all test good.
7. new pass and driver harness, UVHC replaced, glow plugs replaced.
8. new heavy duty GPR
9. Tested IDM no issues.
10. Hutch mod on tank (re-circulator was stopped up) deleted it, added inline filter.
11. serviced fuel bowl with new parts, upgraded parts on fuel bowl new blow off valve, new drain valve, tested heater all good no blown fuses.
12 replaced faulty fuel pump
Might be leaving something out of this list, the truck has run but only for very short periods of time, (hence the dropping of the fuel tank)
fuel pressure at 70 psi, some white smoke, connected to on board computer, checked every conceivable possibility No DTC codes, my gut tells me it has to be fuel related but at this point I just have run out of things to check.
I have tested everything with a fluke multimeter, including the IDM and all the circuits to the 42 as well as all the way to the injectors and glow plugs and find nothing wrong all tests yield valid readings,
There may be other information available but my after market scanner does not show any issue, KOEO buzz test results good.
The three times I have had this unit running it was dumping lots of white smoke, however after the last round of dropping the fuel tank and replacing the fuel pump the white smoke has dropped to a minimum, but cannot get the truck to run, cranks, wants to start, almost starts, got it up to 800 RPM last try but just will not go beyond that point.
I cannot find anything wrong, must be something I am either missing or its something my cheap scanner can't pick up on.

5 months ago I brought a f250 7.3 2000 model the car i always wanted and to take a trip around australia but I am having problems with the 4r100 transmission that was rebuilt before i purchased the truck
The problem and checks. Truck taking of in 3rd can manual select 2nd but not 1st
Getting Codes P0715 , P0717 changed turbine speed sensor checked wiring to pcm all ok codes still coming up
Put truck on scanner and found TSS reading when manually in 2nd but not in park neutral or drive
Removed PTO cover to check gear turning that the TSS reads from with the truck up on stands the gear only turns in 2nd when in park neutral or drive it is stopped verifing what the scanner is seeing the scanner also see the gear changes but the transmission is not changing ...

Problems with my 2001 F250 4r100 transmission. Transmission will only shift to 2nd gear when throttle is feathered at @2500 rpm. All other gears shift perfectly. This problem is consistent.

I have an early 99 F250 4x4 7.3L..... 4R100....
Brief history, a while back on way home from work I let off of the accelerator and had a loud gear meshing like grinding noise, got back on the accelerator and went away, let off and back, so I quickly stopped and pulled over, went through the gears and reverse, everything seemed ok,??? went on my way, got home parked the truck and went about my evening. came out next day to leave and truck wouldn't move in reverse, forward but not reverse. long story short I was told that the snap ring internally probably came out, I have heard of this being a big issue with these, so I set up for it to be rebuilt, got it back and installed and still same issue, what the crap so I ended up having to pull it back out and amongst my own trouble shooting I found the simple issue and was the nylon riders on the 4hi/4low shifter fork were completely gone and allowing the planetary group to free float in and out of 4x4 neutral!!! NOW on to the issue at hand. so far only thing has been done is rebuilt and those fork riders replaced.
now I can move but 2-3 upshift under a load(more noticeable) has a delay going from 2nd to 3rd and under a load it hits hard. I talked to the guy that rebuilt it and he said that the rebuild kits don't always the right springs for the valve body and causes shift issues, so he talked me into the shift corrector kit which I researched and did see what he was saying, so had that done and still no better, still does it, however, it does shift into the gear softer but didn't fix the delay or the hitting hard when it did finally go into 3rd.
After being forced to drive it that way I have since determined that what it happening is it is coming out of 2nd with a second and half pause and then shifting into 3rd, the hard shift comes in to play because during the delay the torque convertor is locking up making it a direct drive like popping the clutch on a standard!!!
I just swapped out the sol pack and I heard from a youtube video that the bolt next to the 2-3 upshift valve on the valve body could be to tight and making a sticky valve, so I re-torqued all the bolts and nuts put all back together and test drive proved to be worse, I now have same issue in all upshifts. all hit hard now, I am at a loss and don't know where to go from here, I can only imaging the sol pack is causing this but I have yet put my org one back in to see... oh and I found two bolts on the accumulator stripped and found one non torqued bolt on the main valve body!!

I have a 4r100 on in a 99 7.3 4x4. The shifting problem I have appears to be intermittant. it seems loose after warm up especially at the 4th shift overdrive and passing gear. possibly due to low presures ? sometimes (lately more often than not) hunts back and forth between 4th and o.d when passing or hill climbing. Under normal driving it shifts somewhat firm with 4th being an exeption.I have changed my crank position sensor filters and fluids which had turned dark and improved slightly. When I pulled the pan and replaced the filter the pan was spotless. No residue or signs of plates or debris. There is about 100,000 miles on the tranny and 350,000 on the truck. Questions: Is there a tcm for this transmission and if so could it cause these problems? I'm considering a purchase of an unlocked 1705 superchip to change the shifting but unsure if this will work for my issues...

My pickup has 316,000 miles on it. It's a 2000 ford f250 7.3 powerstroke. I have always bragged how my truck can pull anything because it has alot of power. Yesterday when pulling a 28' travel trailer up an incline I noticed I didn't have much power and it steadily got worse. Now I'm at a crawl when I hear a noise sounding like it lost air compression for a few minutes then the noise stopped. I stopped and looked to make sure everything under the hood was still attached and everything seemed fine.
I got back in and continued very slowly a few more miles home. Gauge were all good, never got hot. I put a scanner on it and it threw two codes. P1247 and P1248. I haven't noticed any unusual smoke. This is my second ford I've owned and know that when weather gets cold you may have to plug it in. But this truck it doesn't matter if it's 100 outside it will not start without plugging in for at least 1 hour. I've replaced all glow plugs hasn't worked. So I am assuming this break down now has something to do with it. I really am starting to not like fords!

I may be going to look at a 2001 F250, 4x4 with a V10 engine tomorrow. I think it is a shop truck for a business. The owner said that the mechanics told him that the trans won't shift out of low gear. It is an automatic. Maybe something as simple as a modulator valve (do they still use them)?

I have a 2001 f350 7.3 diesel and want some info... I am switching out the air intake and thinking about the Banks package.. How does it can be compared? Also, I am dealing with an issue of a dual generator upper and lower fault codes.. I only have a single generator system and it is running strong as far as I can see.. When I start it shows 12.9 and then raises to 14 when running.. Stays there the entire run...

I've been battling this truck for over a month now and starting to go a little crazy, It's a 2001 f350 7.3L, with a "used" 7.3L engine from a 1997. Transferred all the necessary parts to make it happen. Keep getting the evil p1316 idm codes detected coming back upon start up. Anywhere between 5-30seconds after starting the left bank dies. I've gone threw and replaced the IDM with a reman unit. New valve cover gaskets (with new harness). even went the extra mile and put in a new power wire (for the driver side) running directly from the new valve cover into the IDM bypassing a connector above the left valve cover. All injectors are checking out around 3ohms. With glow plugs all around 1-2ohms. What's interesting about this is, I can disable any one of the injectors on the left bank (doesn't matter which one) and the engine runs great considering it's down on one cylinder. But when I hook up that last injector it will kill the whole left bank again.

I have a 01 f-250 7.3 6 speed. I bought the truck a few days ago and the 4x4 wasn't working the dealer replaced the transfer case motor. I have another 01 f-250 that i have been switching parts out of to see if that makes a differences and found nothing to work. Ive switched the switch on the dash out and nothing. Ive switched the two relays under the hood and nothing. I have also checked all fuses. and the connectors on the transfer case.
So I finally popped the covers off the two relays and squeezed them with my fingers and boom transfer case locked into 4lo and then i can squeezed the other and boom back in 2h! So now I'm lost, I know the wiring from the relays to the transfer case is good and the switch is good and relays are good so I'm at a loss.. Also cruise control isn't working idk if that could be related i don't think it is but idk?

Finally had a good scan done on my truck at the mechanics. The reoccurring codes were P0478 and P0470. It looks like a bad exhaust pressure control sensor. Looks like an easy fix.

The fan clutch will come in and out rapidly when NOT in OD and pulling hills with the fifth-wheel attached. Replaced with a new aftermarket fan, then a new OE one. Then had the radiator pulled and all the bugs, etc. blown out. The condition has not changed at all. The original fan clutch was pretty sloppy. There are no codes, the trans fluid is nicely red, the engine does not overheat or even change temp when pulling hills. No check engine light ever. The truck is a 2001 F250 4 X 4 automatic extra cab with 7.3 engine without any modifications and runs perfect except for this. There are about 95k miles on odo. When we use overdrive on the flats, there is no issue.

01 f250. Just bought from my brother. 140000 miles. Immaculate. Truck will die for no reason. Running down the highway, or sitting at a red light. Fires back up. Sometimes have to crank a few times. He has had at a mechanic and everything checks out good. Since birth its only had royal purple that he has changed every 5000 miles as well as all filters. Where do I start?
