Ford Transmission :: 1993 F350 - 4EOD Shifts Hard
Jul 20, 2014
I have 1993 F-350, 4X4, four door with a 460 fuelie and a 4EOD. That"s a bunch of 4's! I bought this pickup with 186,000 miles on it in 2005 or so, really just to haul fire wood and go to the dump once every 6 months. I don't know if the the tranny has ever been rebuilt. Nothing else on the pickup has been rebuilt. It now has 196,000 miles on it. In the past the tranny always shifted like a stock 4EOD. Kind of slides into the first three gears then into overdrive pretty solid. I took it out to go to the dump last week and it was just like always until it took it to taco party last night and it started to shift real abrupty. Doesn't matter how fast you go, it hits just as hard if you are on the gas or just casually cruising. It is hard in every gear. My first thought was that it may be low on fluid. When it is hot, idling in park after a drive I don't see oil in the little holes on the dip stick. I see oil on the dip stick but not in the little holes. Am I correct in thinking I should see oil in the holes? Actually I will see oil in the little holes when I first pull it out, then if i wipe it, put it back in, I see no oil in the holes. Engine idling in park of course.

I have a 95 f350 with a 460 motor and a e4od trans with 90,000 miles. My speedometer,odometer quit working and then transmission shifts hard in all gears. I've checked the fuses and all are good. I've even replaced the speed sensor but still have the same problems and don't know were to look next. Where or what to check?

I have 99 f350 v10 4x4 and trans shifts great under light rpms but 2-3 shifts very hard. At wide open from about 35 mph it will shift down and take off like a bullet but wont shift until I lift my foot and then it bangs hard from 2-3. All other gears are smooth. I did some searching and have found some threads saying it could be an accumulator spring that is broken? Truck has 115,000 miles on it. love the truck but want to fix this before it does some damage.

I have a 1993 4WD Toyota extended cab pickup with 200,000 miles on it that is getting hard to shift into first gear. I have to double/triple clutch run through the gears to get it to shift into first. It is not hard to shift all the time but the issue is getting more and more frequent.

I have been hoping this problem would go away but it hasn't. I drive a 1991 350 diesel with Banks turbo and transmission module. When we first bought the truck it was only a few thousand miles before we had to have the tranny rebuilt. It was fine for about a year or two when we installed the Banks turbo and then after about five thousand miles the torque converter flew apart and ruined everything inside the tranny.
After this second rebuild it seems to be doing pretty good all except for it wanting to shift in and out of overdrive for no reason. I can have the cruise set on anywhere from 50-65 and when I start up a VERY slight hill it will downshift to third. I know that this engine has plenty of torque to maintain its speed up these small hills without downshifting so something isn't right. On this last rebuild our mechanic contacted Banks about the trans command and they told him to wrap the exhaust pipe with insulation to keep some of the heat off of the module under there and that seemed to work some.
(It shifts better than at first except for going in and out). Another thing that might be interesting is when it was first rebuilt this last time it had a problem with jerky shifts and the tranny light would come on. Our mechanic had to replace some sort of sensor in the tranny that kept breaking. He did this about three times and since he wrapped the exhaust it hasn't happened again. I hope I made everything clear for everyone to understand.

I just rebuilt my E4OD transmission in my 1996 F250 7.3L it has all new clutch packs torque converter and a shift kit. When I first put itback together it would not shift out of second cleaned mlps and shifts threw all the gears now. I took it out on the road to test it and this thing ran great shifted smooth and quick could not askfor any better but when Trans temp gets around 140-150deg it shifts hard and od light flashes. I have ordered a scanner to read the codes but won’t be in till later this week. What I could check in the meantime.

Have an 01 f150 super crew 4x4 with 5.4 li shifts hard from 1st to 2nd - What could be the problem?

I recently purchased a 2011 F-350 w/6.7 diesel. When I first start it & let it run say 30 seconds and take off it shifts fine from 1 to 2 but when it goes from 2-3 it hangs there a second and then finally shifts into 3rd hard. 3rd to 4th is ok but 4-5 again is a hard shift and from 5 to 6 is OK. It will do this for a while like through the neighborhood and down the road 10 miles then it is fine. Shifts beautifully when warmed up.
My local Ford dealer has a guy that is supposed to be very knowledgeable with Super Duty trucks. I have had it to him twice and he says this is normal. All shift hard until the transmission is up to operating temperature. Says the engine is very powerful and until everything is up to temperature this will happen. If so then it would be normal to let it sit and run for a while before you take off in the morning. I am getting ready to hook the truck up to my 33' camper and go on our first camping season with the trailer/truck combination and if I need to leave it sit and warm up I will.

2000 Ranger autimatic, 2.5 lt 2wd, 155,000 miles. To my knowledge it has never had a tranny flush or the fluid changed. I have noticed last week that when you are taking off from a stop sign it jerks going into gear. This only happens when you are taking off all the other shifts are smooth. The transmission fluid color is redish-brown and doesn't have a burnt odor. I don't know where to start. Do I get a tranny flush, change the fluid or is it something else?

2007 escape 4wd 3.0. I've notice some random hard shifts for the past month and today the trans has trouble shifting out of 1st. If I get the rpms between 3,000-4,000 and ease off the accelerator pedal it shifts into 2nd without drama. It will not shift at lower rpms with the same easing off the pedal. The trans light is steadily blinking.

I got this 89 ranger xlt with a 2.9 and automatic transmission. I mainly bought it because it was in such good shape and I was planning on putting a 5.0 in it. everything works on it. the a/c, radio, lights and it runs real nice. the only problem it has is it shifts pretty hard going into second gear. every once in a while it will shift smoothly into second but only like once or twice a day. he said he had recently changed the trans filter and fluid and the fluid does not smell burnt.

So while driving to work I start experiencing some weird behavior with the transmission. It would shift hard and seem like it wasn't pulling hard at all. I looked down and saw the overdrive off light flashing. Got to work, turned the car off then started back up and the light was off. Any thoughts?

My tranny started acting up so I took it to a reputable transmission shop for repair.
Symptoms : Shifts very hard 1st to 2nd. Light flashes on overdrive button.
The following is what has been done at the transmission shop.
Computer failed to read codes. Sent out to rebuild. After rebuild, codes read FIPL needs replace. Done and gives good readout. Trans control replaced, speed sensor replaced, checked all associated wiring and plugs as well as ground. Dropped pan, changed fluid and filter. No parts in pan. Tech says pan and fluid looked good. Replaced coil pack.
After all that, this is what is happening..Clear all codes. FIPL reading good. No flashing light on shifter. It feels like it is shifting from 1st to 3rd, then back to 2nd. Still shifting hard and indicator light starts blinking again. He is going to read computer again. At this point, he suspects a mechanical problem in transmission but is reluctant to remove and tear down.

I have an 2003 F-150 4.6L with a 4R70W transmission, the speedometer goes crazy while I drive, the truck feels like it kicks in & out of overdrive, it shifts hard, the o/d light flashes while driving and I cannot use speed control. I have already checked the transmission fluid, changed the speed sensor, & the range sensor. After changing the range sensor the truck ran perfect for 3 days then the same problems.

And if I have to sift through one more "My O/D light is blinking."
I have a 2000 F350 7.3 4x4 SRW CC with several issues but right now I'd like to address the one plaguing my transmission. If I crank the truck and take off it will not shift out of first gear, well it might but it'll take a while, be at high rpms, and a hard shift, throwing the 1-2 shift error code. Now if I disable O/D with the button on the shifter and take off it shifts through all gears fine. I can drive it normally and if I hit the highway, when I'm up to speed I can enable O/D, it shifts into O/D and I can keep on trucking. When I stop I disable O/D and take off normally again. After about 10 minutes of driving and several start/stops even with O/D disabled it will eventually throw the 1-2 shift error code and give me a harder shift into 2nd and I guess enters its limp mode but is still drivable. This appears to be the only code dealing with the transmission.
Due to the fact that it shifts fine with O/D disabled, doesn't skip any gears, and I can manually shift it through 1-2-D I'm guessing it's not the mechanical diode I've heard so much about but an electrical issue. Before I bought this truck it had been abused, at one point the front driveshaft came loose and ripped the wiring harness going to the TRS in half. They soldered it back together but it still looks a little rough. I figure this is a good place to start. What readings I should get at the TRS? Sensor side and plug side. I have the AE enhanced ford bundle and a good DVM. If the TRS can't cause an issue like this where do I go from here, shift solenoid?
TLDR Version
2000 F350 7.3 4x4 SRW CC
Won't shift out of first with O/D enabled.
Shifts fine with O/D disabled.
Can manually shift through all gears.
Eventually throws 1-2 shift error code.
TRS/TRS Harness has been damaged in the past.
Appears to be an electrical issue with the transmission.
Can the TRS cause an issue like this?
How do I test the TRS/Harness?
If not the TRS what could it be, shift solenoid?

I have a 2011 F250 with the 6.2 34000 miles and my Transmission shifts hard between 2-3 and 4-5 took it to the Ford dealer and they said it is the shift solenoids are bad but it is cause from the Powertrain Control Module and its not covered by the warranty because it is part of the emission system.

I bought a '93 F150 4x4 this past Sunday. It has the 5.8 and E4OD. Yesterday when I started it up and drove to the tire shop for some wheel balancing, it shifted VERY hard with each shift, so hard that it concerned me. I know very little about transmissions in general, and this one specifically, aside from it being electronically controlled.
This afternoon, I drove it again and it seemed to be shifting more "normally" without shifting anywhere nearly as hard as it did yesterday. What I should check first? I bought a filter kit and will change the filter/fluid (including torque converter) as soon as I'm able.

I'm trying to diagnose a problem with my dad's 93 F250 7.3 diesel 4x4 with a ZF S5-42 5 speed manual transmission. It seems to not want to shift back into gear once the truck has warmed up, with 1st, 2nd and reverse being the toughest gears to get into. We've done a transmission fluid change with the required dextron/mercon substitute but the problem existed before the change and the change didn't seem to solve the problem any.
This problem didn't exist until I did a couple hundred miles of towing with it, some of which was done in 5th gear (overdrive?), so I'm hoping the 5th gear towing didn't ruin the transmission. From a cold start the transmission has no trouble shifting into any gear as well as with the engine off when either warm or cold, but with the engine idling and the truck at operating temperature it can be difficult to impossible to shift into gear, especially reverse.
I think heat has something to do with the problem because the shifts were worse a when its driven longer and during the tow/driving that was done in the last part of summer. It sat most of the time since then but we took it out today to test some things. Hot or cold the external hydraulic slave had roughly the same range of movement, but the drive line seems to jerk more noticeably like power is applied to it during a shift when its warm.
This all makes me think, even though the clutch hydraulic system is working like I think it should, that the clutch is not fully disengaging when at temp. I'm not a transmission guy so before I start throwing parts/labor at a problem.

I currently have a 2006 F-250 6.0 with 187,XXX.
My problem that i am having is that the transmission recently within a couple weeks started acting weird about the same time 3 of my fuel injectors started failing. When i start up the truck and put it into drive it takes about 3-5 seconds to shift. Once it's in drive it runs pretty well but it will start shifting out of normal when i go to accelerate. Also when i go to slow down sometime the transmission shifts hard to a lower gear. I also have a video of the sound that it had started to make since its hard to describe.
Here are attached videos and photos. I want to hopefully fix the problems myself so i can learn more about my truck. I am going to handle the fuel injectors here soon since 2 are failing and ones about to these have been causing the truck to shudder at around 47-53 mph but after that its fine.
The transmission is stocked and never been altered, i do admit for 3-4 years I have changed the fluids or filters.
The truck is bullet proofed, sct tuner, upgraded turbo from stock, 4" exhaust, head studs and new everything when the engine was rebuilt and bulletproofed.
I plan on going to ford tmw to have them figure out the problem and hopefully its just solenoids so i can fix it myself. I have a link posted also where you can hear the noise it has been making when in R P and when shifting going down the road and it is a automatic.

I have a 1994 F-250 XLT heavy duty model. No warning lights are on. A few times a month my transmission will start shifting hard, kicking into the next gear. The odd thing is, if I reset the computer it stops. Shifts smooth as butter. The fluid is a vibrant red and the fluid looks great like it's new. What is going on? I'm getting tired of having this happen. The truck has 108,500 miles on it.
