Ford Transmission :: 1991 F350 - E4OD Shifts In And Out?
May 20, 2003
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.

I am looking at buying a 91 f250 4x4 with a 5.0 and an e4od. When I start the truck I can feel It roll forward A little bit. I can put the trans In od or nuetral and It will drive and shift normally thru all 4 gears, no slipping and no noise no vibration, It shifts and acts perfectly normal. 1st and 2nd work fine as well. When I put it in reverse It rolls forward slightly then drops Into reverse, it will not actually back up, you can rev the engine to stall speed but no higher. Sometimes in park If you rev the engine It will actually over come the parking pawl and roll forward.
Also when In park I can rev the engine to stall speed only. It only starts in p or n, and the reverse lights come on in R so Im assuming the mlps is adjusted properly and the manual protion is adjusted properly. I pulled codes and had 3 in total, ect shorted, egr flow insufficient, and 1 code for torque convertor clutch solenoid I believe It was 632. Im assuming the reving up to stall speed Is related to the tc code. The fluid level Is fine but is a little dark In color, I tried doing a search with no luck ..

The trans in my motor home has made a growling or slight grinding metallic noise after it shifts into 3rd gear. It only does it for maybe 3 seconds and it doesn't seem to affect the operation. Only way I can describe it is that it grinds, and shudders then goes away. I have towed my race car all this year and it has not caused any issues at all. I am planning on driving out west next year and would like to figure out what the deal is before I hit the road. Also if a rebuild was in order what improvements can be made during a rebuild?

I have a 78 F350 2wd With a 460. I want to install a 99 E4OD trans. I have the Trans it is rebuilt with all the upgraded parts. I was going to order the converter this week. I am not shure on the best programer to order and shifter to order.

I'm swapping a 90 E4OD into my 86 6.9 F350 and find my injector pump won't take the usual throttle sensor. I'm wondering whether the controller (from a 90 E350) cares about intermediate throttle settings or is it only worried about coast vs wide open.
My options appear to be rigging some sort of linear travel pot, or would limit switches with something cobbled together to give two resistances be enough?

A while ago, I acquired a 1991 Mazda 626 automatic (currently 105,000 miles) that now has what appear to be the beginning of transmission issues. It hard shifts from 1st to 2nd - the shift jerks really hard when the car is cold but once I've driven it for 15-20 minutes the hard shift almost disappears completely and stays that way as long as the car is warm - except for stop and go traffic (Seattle traffic) than the hard shift comes back no matter how long I've been driving. The only other shifting issue I notice is on the hills where it seems to shift more frequently than I might expect it too.
Other than what I've described this car is in perfect condition inside and out, as well as engine-wise. My question is on transmissions and whether I should get a rebuilt one. I've taken it to multiple transmission shops and almost all have told me two things 1) I need a new transmission and 2) that the issue is a hard component problem and I could most likely drive this car for months or years without having to replace the transmission - if I want to put up with the rough shifts. They recommended just driving it until the transmission goes out and then replacing it.

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?

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 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.

My tranny slips in drive and od when it is warmed up.It's fine for a few miles when it is cold.Did a quick search and it seems like it might be a bad mlps.
My question is, Will a bad mlps act up all the time or just when it's warmed up? Will a mlps and connector from a 91 tranny work on a 95 tranny? Don't really want to throw money at it if it will need a rebuild.

My 95 psd recently started shuddering on takeoff... Pretty sure its the torque converter. It has a full ATS tranny with 5 star t/c and all the goodies installed by the previous owner (warranty not transferable). Its only got about 25k on the trans but they have been far from easy miles.
Symptoms: If I hold the brake and keep the truck stopped while holding the throttle its totally smooth, not until the truck starts moving that the shudder begins. It shudders worse the more power i put to it. Does it in first gear and second gear takeoffs. Goes away at about 10 mph or once the speed catches up with the rpm.

I have an E350 1992 7.3l Diesel, with E40D. The transmission slips in the 3rd and OD position. Every time, if I want to accelerate it slips for a few seconds and then the drivetrain is correct connected. The shifting into another gear works properly, the transmissions slips by changing from free-wheeling into accelerating ( for example: at speed 90km/h and no changing the gear).
I have recognized that the oil temperature is getting higher now. That may an indication for additional losses in the transmission. What do I have to check?

I have seen a few threads about E4OD's and there valve issues just want to narrow down to a valve issue or if it needs a rebuild. I can shift threw all gears i just have lag going into 3rd. also when putting it in reverse it takes about 5 seconds to finally drop into reverse. This is also accompanied with P0782 2-3 shift malfunction.

A while back I picked up a 1994 Bronco with a bad tranny for a flip. I recently picked up a 1993 E4OD that seemed to work well with low miles to throw in it.
I got it in the Bronco but it does not work right. If you put it in drive if feels like it's taking off in 3rd or 4th gear pull the shifter down one notch and it feels like 2nd gear pull it down again into 1st and no change. It bangs into reverse really hard. When up shifting manully it bangs pretty hard. No kick down at all under any circumstance and no converter lockup. I can't tell if it's in OD or third gear when at highway speed. OD button on the shifter has no effect but the light does go on and off.
I'm not an automatic tranny guy at all but it seems like an electrical issue. I was not able to drive the truck with the original tranny other than reverse (no bang) but the PO told me it was fine till it started slipping. I did test drive the donor truck and the new tranny worked correctly in it.
Being new to the process I need more detail and some of the basics. I'm comfortable with electronics and have the test equipment I just don't know the procedure. I'm guessing a bad connection/wire or something not compatible between the 1993 tranny and the 1994 truck.

1994 E350 Club Wagon 351w, E4OD Transmission. New MLPS, New VSS, New TPS, New Fluid, New Filter, 5 year old Torque Converter.
The Transmission dribbled a little bit from the front pump seal a couple weeks ago, I checked the level, it was a bit low. Topped it off with Lucas, the dribble stopped. I drove it successfully for another week. I took it on a 10 mile trip, and 5 miles in, it started slipping above, 35mph, I let off the accelerator, and the transmission "Caught up" and I drove 35mph the rest of the trip. I let it sit over night.
The next morning it acted as if nothing were wrong. I drove it some more, and the same thing happened. I parked it, and revved the engine up a bit, and it tried to MOVE in park, I put it in neutral and revved the engine, and it lurched as if it were still in 1rst gear.
This time I let it sit for 24 hours, and after work I successfully put 20 miles on it without missing a beat. It was shifting right, good solid connection between the gas pedal and the road, and I thought the problem was fixed, as the temperature the day before was -20, and it warmed up outside to 30 degrees above.
I parked it for a couple hours and went to go do the errands, and it wouldn't make it above 15mph. It even struggled to do that much. I put it in reverse, and it held great, no slipping at all.
Let it sit until the next morning, and it was better. I pulled the Codes, and it gives me a 63(7) TOT High, and a 62(9) Torque Converter Clutch. It may or may not be relative, but Cruise hasn't worked in about 6 months either. What am I missing here? What could possibly causing this trouble? Fluid is up and new.

My rig is a 1995 F-250 Powerstroke 4x4 with 150k on the clock and an E4OD. It has been well maintained and no major work performed aside from glow plugs recently... That was fun! But that's another story...
The issue: Irregularly and randomly over the last year or so the truck has had a problem going into drive. I'll hop in, put it in Drive and nothing. It's like its in Neutral. It is also the same in 1 and 2. If I put it in Reverse, I can feel it engage and the starts to go in reverse. When it has this drive issue, the only thing that I can do to make it go is to give it some fuel and idle it up. Then it slowly engages and its fine.
Last night it did this... But this time when I could only get it to go by putting it in first and then giving it fuel... It slowly engaged.
Overall its done this maybe five or six times over the last year and doesn't seem to be getting worse. Sometimes it will go for a month with no issue.
This has happened when its warm or cold so I'm not sure heat is an issue. About 10,000 miles ago the transmission was flushed / full service. Oh, and the ATF level is exactly where it should be. My biggest fear is that the transmission needs a rebuild. One local shop quoted me $4200 to rebuild it. What I'm looking for is to know if there is a simpler and cheaper fix. I'm not really interested in a rebuild, unless that is the only option.

having never been into an E4OD, I have a quandary. I have an F-350 with a 460 engine with the E4OD trans. the trans works fine, but wouldn't go into park. I pulled the pan and tail housing and found that the thrust washer behind the park wheel had broken and dropped down to obstruct the pawl from engaging. I have no problem in tearing into a C-6 on back, but the E4OD, I'm not so sure. I had considered just pulling the trans and replacing it with a used one. I can find all kinds of trannies, but NOT the '89 to '91 that I'm told is what is needed because of the electronics. I have been told that the '87 to '97 will work but I have to swap out the electronics? is this so, and how much of a mess is that to do? OR, someone told me that it is possible to use the 4X4 trans by putting on my tail housing? doesn't sound right to me, but what do I know? any pointers????

This has been a problem since I got the truck. It's a 1996 F150 5.8 4x4. It's got about 140,800 miles on it; had about 139,000 when I picked it up. Not sure if the trans has been rebuilt or not. I'm the 3rd Owner. It doesn't matter what temperature it is outside or how far my foot is down on the pedal... Just about every 1-2 shift is accompanied by a little kick/jolt. Going slow..(coasting, about 15mph) and it shifts into 2nd, usually the jolt is harder than hell!
Same goes for when I'm going about 25mph and I put the pedal to the floor It downshifts then comes back up to 2nd gear and wow. It jolts, shakes and shudders. Sometimes (rarely) I don't feel anything when it shifts. But it ONLY and always happens 1-2. not 2-1 either. Furthermore, when I go to put my truck into Reverse it kind of slams into it, with a clunk noise. All fluids have been changed recently and I also put "Lucas Oil Transmission Fix" in it and that didn't seem to change anything. What is going on internally?

I have a 1997 f250hd that shifts into 4th at about 25mph and lugs the motor down, then shift back to 3rd (maybe its 2nd and 3rd). It will keep shifting back and forth until you get up to speed, or if i'm in town i will put it in second.
No codes but the tranny fluid is dirty. I changed the filter the other day but didn't have time to flush it as it was getting dark and the line into the tranny was pretty rusted and starting to strip. Also there was no burnt smell. I'm planning on taking it in to have it flushed this week.
