Ford 7.3L Power Stroke (1999-2003) :: No Overdrive - Hard Shifting From 3rd To 4th
Nov 16, 2016
So I have a 2000 F-250 7.3 and my over drive won't work. I also had hard shifting from 3rd to 4th and 3 gear wouldn't try to shift until about 2500 RPMs which is high. I replaced solenoid pack and no change. I have rebuilt the tranny and found that OD snap ring had came off I put upgraded spiral ring on. When I went on a test drive I found out nothing had changed except shifted smoother. So I changed valve and accumulated body still no change. Truck is throwing 4 codes:
P0733 Gear 3 incorrect ratio
P0750 Shift Soleniod a fault
P0783 3-4 shift error
P0541 intake air heater a circuit low
Could it be PCM??

I have a 2001 3/4 pickup. Sometimes the over drive light flashes. When it flashes it shifts really hard and sometimes it won't shift into 4th until I mash the overdrive button. Sometimes the light doesn't flash at all and it doesn't have any trouble shifting at all. Is it a solenoid? Or wiring issues?

I have run into a problem. My early '99 7.3 PSD decided to throw a very hard shift at me the other day, lit up the SES light and I had to limp it home going 5mph.
I looked on here and found most problems that caused power loss/engine die and replaced the ICP, IPR, EBP and tube, and the CPS. I also did an oil change after all of that to make sure everything was clean when I went to start it up.
BUT, when I tried starting it, nothing happened. It cranks, but does not start. What is the problem? I watched hours of videos and read hundreds of pages of instructions on how to replace everything, and now the truck won't start.

I have a 01 7.3 F-350, 120000. I rarely get down hard on the go pedal but a while back I did and heard at pressure whistle just before it would shift. I thought a bad turbo hose so I replaced them all. 'While working on the hose mounts I cleaned up the castings for a better seal'. The hose replacement seemed to get the running but the whistle is still there. I am thinking a leak on the manifolds for the Y-Pipe connection OR does the turbo have a release valve that can make a whistle sound?

I put a ts6 on my 2001 7.3. I love it shift points are better and truck has a lot more power. But I've noticed when I shift truck shifts into 3 (especially going uphill) I get a really weird turbo sound where it acts like its gasping for air (I have 6637 air filter) and then it shifts kinda rough into third. If I put chip on stock setting it doesn't do either of the things I described. Do I have loose turbo boots somewhere or possible bad turbo bearings?

2000 powerstroke 4r100 transmission. It has 155k just had it rebuilt and the shop is having a night as am I. It was shifting hard and the o/d off light would start flashing after you drove it a while. Its still doing the same thing and the shop checked the whole wiring harness and replaced the accumulator twice believing they got a bad re-manufactured one. The only code I can pull is a 605 pcm read only memory error. Could the cause be a bad pcm? The shop doesn't seem to have a clue at this point and I'm out 2500. IV taken it back twice now and Iv driven it a total of 35 miles since the rebuild...

The overdrive light is flashing but not all the time. What does this mean?

My F350, 7.3 L. is flashing the overdrive light. Had a pro do a scan that said no Turbine speed sensor signal.
I would like to know where the TSS is located and then see if it has corrosion other reason not to connect.

So here's the deal: My 2000 F250 has began to have the overdrive light blink when I am traveling at low speeds <40mph and it is accompanied by strange shifting (lower gear for a longer period of time). As soon as I get up to highway speeds the blinking stops and goes back to normal operation. But as soon as I go back to low speeds it happens again. When I put the truck in to park when it has the light blinking it revs it self to about 1200rpms then goes back to normal idle. This truck has 228k miles and is on the original transmission.

Auto trans. The Overdrive light flashes on the Selector lever. Never stops.I put tape over it because it is annoying. Especially at night. It goes into overdrive no problem.
A Couple of times it did not flash and was stuck in first till I manually shifted. Then the light started flashing again and works normal. What now......RPM Sensor?

Went away shifted great threw all the gears.

I have a 1999 F250 4-wheel drive with a 6-speed tranny. The tranny is several old but has only around 100k on a rebuild. Three times recently it has stuck in 6th gear (overdrive) and I had to get really rough with the stick to get to come out. Afterwards the stick felt "thick" for a while and eventually everything seems to go back to normal. Not for sure but it may have started after pulling a heavy load, around 16k, which is not unusual for the truck. Other than the times it stuck and shortly after, the tranny seems perfect.

I have a 2000 f250 with the 7.3 and 181,000 miles on it, recently got stuck in the snow (in 2wd because i forgot to lock the hubs) and the rear wheels did alot of spinning. Now i randomly have the OD light start to blink, sometimes its a half a blink, sometimes it'll stay on for a few seconds, itll do it randomly while crusing down the road at a constant speed, also noticed my rpms fluctuate a tad at idle.

Its going into overdrive to early causing it to shake at around 40mph but when I get to 50mph it go away or under 35mph it not there either what could that be??? Just got torque converter and trans done and checked it wasn't that.

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...

Anyway I have a 2001 F250 7.3l 4X4 supercrew 8 foot bed. Have an upgraded turbo, 4" exhaust from turbo back, k&n cold intake. Has 207,000 miles on it, 198k from first owner, the rest from me. Anyway the transmission is a automatic R4100 tranny. Since I have owned it it would shift from 3rd to 4th on slight grade. It would continue to shift up and down till I got back on flat again, rpm's would not vary to much depending on the grade. So that problem continues and now today I was towing a 14' trailer with 3 wheelers on it and I smelled smoke. Pulled over and it was pouring oil from the bellhousing. I had no choice but to drive back home about 20 miles. I first stopped and poured 2qts of ATF fluid in and then babied her home. What are my options here, what I should be looking for to fix?

2002 F-250 tries to die when I shift from drive to reverse. Usually first 10-15 minutes after starting. After it has gone a few miles I haven't noticed it. Seems to be getting worse but just really started a few weeks ago. I don't drive it everyday so it has been a while.

I spoke with a few people here before about my 4r100.. it threw a code a month ago for P0750.. i replaced solenoid and it continued to do it even after clearing codes numerous times.. then all of a sudden it was perfectly fine for over a week, no codes, i ran a few brick hauls with it and ran it for over an hour straight.. i went to fl and upon return i took her for a drive and wouldnt you know, the code has returned.. i did hammer down a little but not from a dig, i just got on it a little playing with a neighbor and his truck and all of a sudden it did its thing slipping and not up shifting then the O/D started flashing again... i cant understand why the code would come back all of a sudden, there has to be a wiring problem correct?

So I put in new clutch yesterday. Reverse works, granny works, 3,4,5 work. ZF6 manual. But when I try to go 1st or 2nd. Its as if the truck is in neutral....what should I be looking for. I bought the truck having only knowing the clutch was completely shot, was not told about this 1&2 gear issue....
Do I need to pull the trans out again... or is there something I can see or adjust, because from what i can see where the shifter connects there is no adjustments. Is it probably a gear selector fork...or connection that took a crap. when moving in granny gear i did not hear any irregular noises....
