E4OD troubles

[faded150]

Hello, new guy here. Hoping to get pointers on the care and maintenance of an older f150.
The transmission is acting up, big time. 1st, reverse and OD work fine.
It started out as slipping when shifting into 2nd gear and making some serious noise and vibration. That progressed quickly to doing the same shifting into 3rd, and having problems while in 2nd.
The fluid was very clean and freshly changed by the po, within the past 100 miles or so it is starting to get burned. I think the truck and transmission have about 120,000 miles.
The codes came out as KOEO 67, CM 33, 62, 67. I don't know how to get the KOER codes.
Near as I can tell the 33 "egr" is a stray engine problem, the 67 "nuetral safety switch" is somewhat puzzling and the 62 "convertor clutch" doesn't sound promising.
My plan of attack is fresh fluid & filter (ouch at the price of tranny fluid around here, does it really take over 3 gallons at $4/qt?), clean all the electrcal contacts, check the accumulator while the pan is open and hope for the best.
Any other suggestions?

Hello there.

I'd say the EGR code is a vacuum leak, usually is. But don't rule out the EVP sensor or the valve itself.

The Neutral Safety Switch is there to make sure you don't start your engine in gear. Don't sweat it over that code.

And i hate to say it but it sounds like your TC is on it's way out. Sloppy shifting, burnt fluid are the usual symptoms. But yes, definitely check electrical connections down there. You might get lucky and have it be something that can be easily fixed.

Good luck

That code 62 can actually represent two different things depending on what kind of code it is. Is it a continuous memory code (stored in the computer while the truck was being driven) or a KOEO code (thrown during the self test when you were pulling the codes)? A code reader will tell you which kind of code it is. You can also do it using the paper clip method.

 

[Black150]

You know what Chris, you're right. Let's hope it's just electrical.



EDIT: 62 can come up as a CM code "converter cluch error", or KOEO code "pressure switch circuit failed open"

The 33 and 62 codes are not KOEO codes, they can only be CM or KOER codes and you do not know how to run the KOER test they would have to be CM codes..
The 62 code indicates excessive converter clutch slip detected.
The 33 code says the EGR valve did not open. Vacuum problem or the sensor on top of it as said above.
The 67 code says your A/C was on when you did the test.

 

[Skandocious]

Bill the 62 CAN be a KOEO code...

But I just noticed that he specified what kind each code was:

The codes came out as KOEO 67, CM 33, 62, 67.

Sorry it looks like you are going by a bad chart.
Here is an image from the FORD shop manual.

Fair enough-- I trust the Ford manual more than anything else.

there is a TSB on the E4OD.. may have to have it rebuilt, might wanna check that out..

Skan, do you find it weird that most of the E4OD troubles are surfaceing right now? lol mines still acting up

Haha yeah seems like a lot of guys are having issues on the board right now... I'm sure it's just a coincidence

They have had problems happening since they put them in. Not really any more posts than usually.

About 120000-150000 miles is when 90% of trans r rebuilt here according to shop . EVen with servicing. But put a bunch of 10 plus year old trucks together in one place and things happen .

Lines/coolers rust Sensors servos age and fail .

In my case it's because I didn't need to find a ford truck website until I had a problem.

Glad to have u anyway.

Once smoked the e40d is to happy a camper. Sorry.

I found a place I can get rebuilt resonable. Problem is I had just spent
$1500 getting one rebuild .

After rereading this one it sounds like you may have a bad converter drainback check valve.

This was pointed out in TSB 94-21-14.
here is the PDF.

sounds right, when you have the tranny rebuilt, they replace the converter as well.. at least they did with mine

 

[faded150]

well, fluid and filter change didn't do much if anything. The only difference I noticed is that manual first and drive in first gear are different, with manual first slipping less.
Luckily this isn't our daily driver. I am looking for another trans now.

I'll try the convertor check valve per the tsb, but not expecting much.

What else does the nuetral safety switch do?
Mine works fine as far as only letting it start in P or N. Reverse lights come on when they are supposed to also. What else would trigger this code?
Is it even the right description for that code?

 

[NeXtras]

Neutral Safety Switch:
"This switch opens (denies current to) the starter circuit when the transmission is in any gear but Neutral or Park. Standard transmission cars will connect this switch to the clutch pedal so that the starter will not engage unless the clutch pedal is depressed."

 

[subford]

What else does the nuetral safety switch do?

I take it you are asking what does the MLPS does on the side of the transmission as far as the transmission is concerned.
It changes the voltage going back to the computer to tell the computer what gear is selected.
