@@ronnieford3824 A friend who is a mechanic helped me. He found a diagram of the ECM pins and we found the ones (wires) going from TPS and ECM and then tested them one by one. Found one that tested bad.
Also I probably mentioned this to in my posts but I will again. I had a brand new TPS sensor from AutoZone and it tested bad. So make sure to double check any new sensors you use.
The electronic switch behind the shifter (MLPS) on the transmission gets packed with road dirt, remove it and you will see an obvious design flaw There is no way the plastic rotating piece inside can work once filled with dirt. The book says to use a gear position sensor adjuster tool T89T-70010-J after cleaning / replacing? Maybe put some location marks before you remove it? $25 for a new one. Good luck. This fixes un wanted up shifts,down shifts and trans going in neutral for no reason.
I have a 1994 Ford F150 with the E40D Tranny. Driving on the Highway it Randomly goes Neutral, then goes back into Gear on its own in a couple of seconds?
I have a 95 Bronco and it has similar issues. Goes straight from 1st to overdrive so I have to shift it manually. Changed the VSS and no change, but when I unplugged the VSS it shifted through all the gears just late hard shifts. Crazy. I'm going to try to change this plug myself and see if it changes anything. Thank you for the video.
I also have a 95 bronco doing the same thing. Just wondering did you ever locate the problem. I know it’s been a year since your comment but hopefully you can help
Some have the speed sensor on the transmission, mine is on the differential. Lucas transmission oil solved my hard shifting problem in less than 5 miles of driving & helped me get another 2 years of work out of it. Now it's done for.
Have a 1996 F250 7.3 turbo, at 35mph it jumps back and forth in gears and when starting out I now have to fully release fuel pedal for it to shift from 1st to 2nd. Where should I start? Several people have said to change shift pack.
@@Gambino559 Needed new gauge cluster. Got 1 from a junk yard , took about a half hour to change out and took care of speedo jumping back and forth and shifting gears at 35. Solenoid pack in transmission took care of 1st to second shifting. also changed sensor in rear end just to be safe. Everything like it should be :-)
mad shifting on my f150 was the TV pressure , i adjusted the cable for 35psi and 0 psi at idle , worked a treat now it knows what gear it should be in Rob NSW Australia
Sept 6 2023. Stuck on side of road lol. 460 ford triple e Motor home. Doesn’t want to switch gears and then it dies. Was told the engine light coming n was only the o2 sensor. So we drove it anyway 😢
Hi mine doesnt do anything only forward in the same shift and R alredy change the selonide pack for the 1991 that has a more width conector but still no results i am thinking in buy a chick 4 stand alone transmition module but i am not sure yet
Watch all my videos.. check your TPS sensor, your speed sensor and your wires. Mine was a signal wire that was bad on the TPS sensor wires from sensor to ECM. Check these things first it's cheaper than a six hundred dollar stand alone that may not be ur problem.
Mine revs up n down like it can't decide which gear it wants either first or second n once it finds the gear it falls on its face a little n shifts fine after that but it's always when I take off somewhere n it reaches its peak of maybe shifting to second it does this....96 4wd crew cab 460 truck
My truck is stalling. I’ve put probably $1600 in the engine trying to fix. Come to find out, I think it’s been the E40D the whole time. Would this possibly be a torque converter problem or the trans itself? Symptoms: Shifts like shit and shifts really hard and will stall and die, especially carrying a load (trailer)
Check and replace if needed: Spark plugs Spark plug cables Distributor cap and rotor Fuel filter Air filter Exhaust manifold gaskets O2 sensor (this one you should run a KOER diagnosis, I could bring you all the info if you need it) If you checked all, and still runs like crap, replace the oil filter and half the old oil from the transmission to get it working, if you do it and still the same, check all your wiring for the engine and transmission, for this you should go to an electician to get it checked
The issue that I am having I replace the solenoid pack my transmission goes into 1st 2nd and reverse but there is no 3rd or overdrive the overdrive button is flashing the wires that run to the solenoid pack are all exposed tried to tape them up do you think maybe replacing the harness part when to fix the issue has the new torque converter rebuilt trans new solenoid pack I just don't know where to go from here it's on a 95 F350
Replacing the plug on the transmission would be an inexpensive thing to try. Also, have you checked or replaced your speed sensors or your throttle position sensor?? Might be an issue there.. Good luck. Please note; I am not a mechanic just my friendly advice.
Do you have also low power, misfiring-like when you're at highest speeds on uphills (when 70 mph slow down to 50 or lower) and shakes a lot back and forth? Check spark plug wires, sparkplugs, distributor cap and rotor, if you still get bad performance, replace your coil
I have a different issue. Just bought a 1989 F350 7.3 idi with the E4od and 28,000 miles. After having it for 2 weeks and putting about 200 miles on it, the od light just started flashing. Other than the light flashing, it has no issue, shifts normal, the button works shifting in and out of overdrive, and no limp mode or rought shifting. Anyone have some ideas?
Check your tps sensor middle wire volt meter throttle closed 1.2 open 4.0 note the 4.0 wide open can range a little but be sure to unplug your high idle cold start solenoid
I have the same problem as funnyman described one shop told me torque converter did that it didn't fix the next shop tells me throttle position sensor did that didn't fix ligt keeps flashing shifting is fine any idea what it could be?
I have a 96 f250 with the 7.3 my OD light was flashing for a bit and just stopped but my tranny has been slipping and this morning wouldn't shift into 4th I my engine light is on but it does work I'm not sure what could cause this problem with out the engine light coming on any ideas?
I have a similar problem with my 1993 f150 5.0 E4OD automatic transmission. It hesitates upon acceleration. I have no check engine light on but when I ran a code reader it showed two codes. first code was 621 which shows to be "Solenoid/circuit failure - shift solenoid 1 - transmission". The second code is 629 which shows to be "Torque converter clutch circuit fault - transmission". The only thing I can think of doing is replacing the transmission solenoid pack while doing a fluid change in hopes that will clear the codes. If someone could help and give some advice on where I should start would be appreciated.
I watched alot of videos, these transmissions seem to have alot of problems. Replacing the solenoid pack is not too hard or expensive. I would check the wires and plug at the transmission that seemed to be a point of problems for alot of others according to their videos and responses to mine. The plug is cheap like less than 40 bucks. If the wires at the or near the plug look bad, I would start there.
Mine shifts HARD after warming up. It dances from overdrive to drive up and down hills. Read a lot of treads out there. A lot of people throwing parts at it. Crappy design to much electrical and vacuum crap with no real computer codes. Paid 1k for my truck. Have a 95 straight 6 also with manual transmission. Am gonna strip the 94 down and junk it. Its just poor technology in this timeframe. I liked manual linkage. Newer trucks have better diagnostics. Thinking of getting away from this old crap. Was also told that Ford's plugs for any electrical plug in for wiring harness are made of cheap metal and degrade. I've had an 84 89 straight 6. No problems. 86 92 01 duallys 86 no problem. 92 had electrical issues. Sold the 01 at 70k had cam sensor go out. Had 3 escorts all had electrical issues. Still have one. Dash lights out defrost in rear out. Pause when I start it at times before it cranks over. Chevys were worse. Dodge always had weak transmissions. Bought my first Toyota. Am thinking that might be better. Good luck motor home guy.
Thanks for the comments. Recently spoke to a friend who ditched his E4OD for a C-6. I did throw parts at mine too. Good thing the parts cost were low and even took some back. Figure any new part on such an old vehicle can't hurt. Do to some bad diagnoses I had to do process of elimination to find the problem them the bad wire. Mice chewing harness didn't help either. My problem is still fixed and I have driven over 3k miles towing a trailer. So far so good!!
@@2lotony glad someone got it fixed. I understand you had a motor home. That's a much more valuable animal. I am very grateful to you guys for sharing. Very grateful for RUclips, this has helped me a lot. Enjoy your motor home. You surely earned it.
My 97 f350 with a 460 has the delay issue on turning the key...for a couple of years now. Almost like a low battery, but It will do it even when it's charged up to 12.5. It's worse if I haven't run it... even though it's at a full charge.
What sensor? The TPS sensor should be on the throttle body. All other sensors for my transmission were inside the transmission. I sold the vehicle last year.
Tail/brake light bulbs must be OEM and in working condition. The trans receives a signal fron them. If there's a 3rd brake light, check is aswell. I ruijed my transmission by power braking like an asshole.
Idk about that cause my reverse lights never worked I fixed it awhile ago but I'm just now having issues with my r100 maybe the filter fell inside the transmission
I wonder if thats why I keep getting the 74 code when everything working fine. I changed my taillights to leds long before. Also got a new brake switch
Problem Fixed! I had a bad signal wire on my TPS. Had to run a new wire from TPS to ECM.
How did you go about locating the bad wire? I changed the tps on my motorhome and it ran like a champ for a day.

Did either of you figure out your issues. Mine is doing the same
I'd like to know as well if that fixed it. I have a 94 f250 that is doing the same thing but I've replaced the vss but not the plug
Change the plug they go bad or run a jumper wire till you can get a new plug
Same issue. What was the fix????
I'm having exactly the same problem. Don't know what gear it wants to be in,cruising through town,17 to 25 mph is really bad.
Not fixed yet. Haven't finished inspecting all the wiring, hoping finish soon . Nothing found so far.
