I have a E40d transmission on my 1992 Ford f-350 diesel. The transmission is shifting hard, just replaced torque converter last year. Does the tranmission have a sensor or solenoid that could effect this. I have 155,000 miles on truck. Could filter be problem. Could you tell me where any of these electrical sensors might be located if all possibly they might be the problem.

E40D (no engine told) wiring is not the same on all. it is fully electronic controls.
the PRNDL is odd , it has resistor bank there that allows 1 wire
aka gear selector switch range switch TRS ,P/N , but is PRNDL.

to trans to let TCM know what gear you want.
TCM is >>> , EEG
2 shift solenoids. 2 for clutch, and pressure control too.

The EEG , sets main line pressure in the box. if this fails , it can shift harshly.
does autoshift al gears? or not.
never read Haynes/chiltion rags,. I use them for door stops
then take 10- years of cars and mix all that up in to a toxic soup of waste. avoid it like the plague. it is, use real shop manuals from
ford only or only line here.

testing the range switch is first.
PRNDL , it is prime inputs.
if wrong all fails.
harsh shifting , can be the transmission accumulator bad.
a kind shift shock absorber it is.
or the EPCS bad, the TCM modulates this to use the correct line pressure for every gear, in fact all these PRNDL
is reverse harsh or PRND shift to driver harsh?
the service manual by ford, for E40D , covers all line pressure test to prove EPCS is messing up.
EPC solenoid, electronic pressure controls

their should be a drain plug in the bottom of the torque converter accessed by removing the metal plate at the bottom of the bell housing facing the engine sump

ISSUE
Some vehicles with transmissions built prior to 11/13/95 (5L13) may exhibit a driveline resonance/vibration between 1400 and 2000 RPM with the torque convertor engaged. This may be caused by the torque converter.
ACTION
Prior to torque converter replacement, refer to the following Service Procedure for details to verify conditions.
SERVICE PROCEDURE
1. Verify the resonance/vibration does not occur in neutral and is most noticeable between 1400 and 2000 RPM with the converter clutch engaged during medium to heavy throttle conditions. Also watch for the vibration to diminish at engine speeds lower than 1400 and higher than 2000 RPM. If the concern meets all of these conditions and the transmission has a built date prior to 11/13/95 (5L13), replace the torque converter. Refer to the appropriate Service Manual for removal and installation procedures.
2. If the vibration concerns do not meet the conditions, check for non-factory installed items that could affect driveline and verify proper installation. Also refer to the appropriate Service Manual, Section 05-00 for diagnosis and testing.

The torque converter to flex plate torque spec's are as
follow's.(listed by transmission)
A4LD
20-34 ft lbs (27-46 N.m)
AOD/C-6/E40D
20-30 ft lbs (27-41 N.m)

Here is what code E40D is:
TRANSMISSION - E40D - DIAGNOSTIC TROUBLE CODES - WATER INTRUSION OF THE MLP/TR SENSOR
TRANSMISSION - E40D - POSSIBLE WATER INTRUSION INTO THE MLP/TR SENSOR CAUSING SHIFT CONCERNS AND/OR HARSH ENGAGEMENT CONCERNS
TRANSMISSlON - E40D - SHIFT CONCERNS AND/OR HARSH ENGAGEMENT CONCERNS DUE TO WATER INTRUSION OF THE MLP/TR SENSOR
1989-94 BRONCO, ECONOLINE, F-150-350 SERIES, F-47, F-53, F-59
here is possible fix:
ISSUE: Some vehicles may exhibit a shift concern and/or a harsh engagement concern due to water intrusion into the MLP/TR sensor and vehicle harness. There may also be a number of different DTC's along with those concerns.
ACTION: Replace the MLP/TR sensor and vehicle harness connector if signs of water is evident.

yes they will i think all the way up until 97 they are the same could even be more year than that! but if you have a 94 you should have no issues putting it in the 92! good luck man and if you have any more question please ask...

mogalator valve sticking

your transmission is slipping

the automatic 4R70W calls for 13.9 if equiped with oil cooler 13.2 if not

if you have the auto E40D it calls for 15.9 with cooler 15.2 without and this is 2wd
the E40D with 4wd calls for 16.4 w/cooler 15.5 without.
this is all measured in qts.

if this helped which i know they are right through mitchelondemand throw me some blue ;) take care
erik

if you need transfercase specs just send me a message

There is only 1e40d for all 5.8 windsor transmissions ,so I got a used one off a van. Auto zone is wrong by offering 2 types, one for the supercab and 1 for the regular.
