What and where are the 4/3 & 3/2 circuit they are from dtc 67

yo dude!

confirm it is 67,

cause KOEO 62 - 4/3 or 3/2 pressure switch circuit failed open - E4OD excessive converter clutch slippage

KOEO 67 = Neutral safety circuit failure (Transmission Manual Lever Position (MLP) sensor circuit)

KOER 67 = A/C circuit was on during KOER Self-Test is

the code 62 can be generated by

excessive converter slippage or a delay in the electronics

or hydraulics. If the trans has ever been re-built, especially

over the past 5 or 6 years with all the updates, it is

likely a slipping converter. If this is the case and the

trans works fine otherwise, you may be able to replace the

converter and let' er rip. If you have to replace the

converter, look for one with the latest HD clutch. I have

the LUK in mine which was custom built. It locks a bit hard

but gets the job done. There are other causes of a code 62.

The electrical wiring can be checked pretty much from the wiring

harness if you have an ATSG manual for it. You should be

able to find the manual online. I get them from the local

parts supplier for about $14 each.

what do i do about a code 67 how do you fix that. my transmission works fine i have almost 190,000 miles on it i was told i should have it rebuilt and change the converter but if i don't need to i don't want to but if its good preventive maintenance i'll just knock it out what do you think

i have a 17 bolt transmission pan isn't that a c6 transmission? i have a 90 fullsize w/302 and its 4wd forgive me if i sound unintellgent when dealing with these problems this is my first time doing any real car maintenance i'm used to working on jet engines

no problem, been there too!

unless someone swapped it out it is an E4OD;

look @ Chris's Pan Diagrams to confirm;

E4OD has 19

C6 Does have 17

and by Baumann

The E4OD four speed automatic transmission is used in F and E series trucks, as well as AOD and AOD-E/4R70W four speed automatic transmissions. To determine which is used in your vehicle, follow these guidelines:

If the shifter has a P-R-N-OD-D-1 pattern, the transmission must be an AOD (applicable to 1980-1993 vehicles).

If a 1989-1993 truck has an Overdrive Cancel Switch and a P-R-N-OD-2-1 shifter pattern, then it is equipped with an E4OD transmission. With the possible exception of some 4R70W equipped 1993 E-150 vans with 5.0L SFI engines (The existence of a 1993 4R70W van is unsubstantiated).

1994 and later vehicles with four speed automatic transmissions will all have an Overdrive Cancel Switch and a P-R-N-OD-2-1 shifter pattern, but may have either an E4OD or a 4R70W transmission. All 4.2L, 4.6L and some 5.0L engines use the 4R70W transmission, while diesel, 4.9L, 5.4L, 5.8L, 6.8L and 7.5L vehicles always use E4OD

don't think it is the prob...do the Self Test again and figure out what Code it is.

and more info on loss of power such as; when..when engine is cold,

or all the time;

at any speed?

any harsh shifting thru gears?. etc.

its any time sometimes it doesn't want to shift and i have to shift it myself once i hit 15mph i lose power and i have to lightly step on the gas to get it to accelerate sometimes it feels like its jumping between 1st and 2nd when i start out. when i initally drive its fine but once i hit 15mph it starts flipin out

 

[miesk5]

ok, do the Test again and make sure it is 67; if it is..I'll be away until Monday,, look at my site for AODE info and DTC possible causes.

GL!

its P-R-N-OD-D-1 the first part of my vin is 1FMEU15, will the mlp fix the problem with my engines loss of power when i'm driving

Sorry my friend, it won't have OD if it is a C6

ck the diagrams Chris has @ his site to confirm what tranny it is; code 67 is da thang to fix; will look at all your posts again to see if i can figure this out ad will try to reply again soon; have a lot of work coming in this week.

EGR Valve Position (EVP) Sensor & EGR Vacuum Regulator Solenoid (EVR) Testing by Dustin S

EGR Valve Position (EVP) Sensor Operation & Testing, Ford by tomco-inc.com

http://www.tomco-inc.com/Tech_Tips/ttt19.pdf

On Fords with computer controls, the EGR is electronically controlled

and there is an EGR Valve Position (EVP) sensor attached to the top of

the EGR valve. The most important thing to remember about these

systems is that the computer relies on the EVP sensor for more than

EGR flow. It uses the sensor input to compute timing advance and

injector pulse width. Check the EVP sensor in much the same way you

check a throttle position sensor using a DVOM or, better yet, a

labscope. If it is defective, replace the EVP sensor and EGR valve

together to prevent inaccurate signal voltages.

The Ford pressure feedback electronic (PFE) system monitors exhaust

backpressure and sends a 3-5V signal to the PCM. (Less than three

volts would indicate a vacuum in the exhaust system­a rather

unlikely prospect.) At idle it should be 3.0 volts and at maximum

backpressure, almost 5.0 volts. High readings at idle indicate an

exhaust restriction, low readings an exhaust leak. The backpressure

hose on these systems has been known to clog up from carbon and

condensation, which can be a diagnostic devil if it turns to ice in

the winter. If you must replace the hose, do not use regular vacuum

hose. It must be able to withstand the high heat. by buddy, Bob!

so, ck for a possible open or a short to gnd

& there is a GREAT chance there is a large amount of carbon that restricts the EGR valve passages as well as da idle control valve, & ck for crap stuck between the pintle valve & EGR valve seat

btw this is a neat product!

it was one of the guys i work with he works at the auto shop on base but he said he didn't know alot about transmissisons he said i should look into it thats why i came this site to find out what to do he drove it and told me he thought my torque converter was bad. i drove it for a longer distance yesterday but i couldn't get it over 45mph i'm praying that it is something electrical because it ran like a champ up until a month ago

ok

"something electrical" = VSS; a simple fix

here are more symptoms of a bad VSS Sensor:Harsh engagements

firm shift feel

abnormal shift schedule

unexpected downshift may occur at close throttle

Torque converter clutch will not engage

loss of anti-lock brakes

the "anti-lock" or "brake" warning lamps on the dash may be lit

RPM limiter may be decreased

automatic transmission shifting may become erratic

other symptoms may also be present

 

does your speedometer go hay wire too?
