I bought this one it's useful to me

The next test involves measuring the resistance of the soloniod valves. There's a thread on here all about it, only I can't find it at the moment.

Check for Hippo's videos on Youtube for some excellent assistance. The values are as follows. Start at the ECU end then work your way to the connectors.

Method 1 is from the circular connectors:

Method 1: Sensor resistance limits (connector C0243)
Pin 1 - 2 = Turbine speed sensor (513 to 627 ohms)
Pin 3 - 4 = Intermediate speed sensor (513 to 627 ohms)
Pin 5 - 6 = Vehicle speed sensor (513 to 627 ohms)
Pin 7 - 8 = Fluid temperature sensor See Table Below

Method 1: Solenoid resistance limits (connector C0243)
Pin 18 is the common for all solenoid measurements.
Pin 9 - 18 = Shift solenoid valve A (14 to 18 ohms)
Pin 10 - 18 = Shift solenoid valve B (14 to 18 ohms)
Pin 11 - 18 = Shift solenoid valve C (14 to 18 ohms)
Pin 12 - 18 = Low clutch timing solenoid valve (14 to 18 ohms)
Pin 13 - 18 = 2-4 brake timing solenoid valve (14 to 18 ohms)
Pin 14 - 18 = Reduction timing solenoid valve (14 to 18 ohms)
Pin 15 - 18 = Line pressure duty solenoid valve (2.6 to 3.2 ohms)
Pin 16 - 18 = 2-4 brake duty solenoid valve (2.6 to 3.2 ohms)
Pin 17 - 18 = Lock-up solenoid valve (12 to 13.2 ohms)

From the gearbox ECU:

Method 2: Sensor resistance limits (connector C0932)
Pin 5 - 20 = Vehicle speed sensor (513 to 627 ohms)
Pin 21 - 20 = Intermediate speed sensor (513 to 627 ohms)
Pin 24 - 20 = Turbine speed sensor (513 to 627 ohms)
Pin 39 - 20 = Fluid temperature sensor See Table Below

Method 2: Solenoid resistance limits (connector C0932)
Pin 17 is the common for all solenoid measurements.
Pin 3 - 17 = 2-4 brake duty solenoid valve (2.6 to 3.2 ohms)
Pin 4 - 17 = 2-4 brake timing solenoid valve (14 to 18 ohms)
Pin 10 - 17 = Reduction timing solenoid valve (14 to 18 ohms)
Pin 14 - 17 = Shift solenoid valve B (14 to 18 ohms)
Pin 15 - 17 = Shift solenoid valve A (14 to 18 ohms)
Pin 16 - 17 = Lock-up solenoid valve (12 to 13.2 ohms)
Pin 17 - 18 = Line pressure duty solenoid valve (2.6 to 3.2 ohms)
Pin 52 - 17 = Shift solenoid valve C (14 to 18 ohms)
Pin 53 - 17 = Low clutch timing solenoid valve (14 to 18 ohms)

Fluid temperature sensor resistance values: (connector C0243 and C0932)
-40 degrees C = 54900 ohms
-20 degrees C = 16700 ohms
00 degrees C = 6020 ohms
20 degrees C = 2500 ohms
40 degrees C = 1160 ohms
60 degrees C = 590 ohms
80 degrees C = 330 ohms
100 degrees C = 190 ohms
140 degrees C = 80 ohms

my result

i am mechanical engineering that meaning if you need to explain about this table , please explain slowly i need to understand

All your results appear to be high by the same margin.

Take the two probes of the meter and hold them together, this should give the resistance of the leads themselves which can then be subtracted from the results.

Your 2-4 brake duty is a little higher than the rest suggesting it be out of spec. Mine was and gave a very harsh gear change and no 4 & 5th when warm.

resistance was 1 when i connected together

yu sure?

yes

And you measured them all off the round connector?

If so they are all way out of spec.

I follow Hippo's videos step by step
That mean i need to change soloniod

Based on those readings yes but then I am suspicious they are so far out.

I would repeat the test from the gearbox ECU loom and check the readings.

Tomorrow i will do that and i will send results

Be careful when you probe the plug and insert the probes in the top of the plug [where the wire goes in] and not the little tabs that are visible on the front of the plug as these hold the connecter in.

Nodge68 · Mar 4, 2016

I would find a more accurate multi meter tbh. I have one of those and it's 10 or 15 % out on some ranges. You need something with an accuracy of 5% or better.

Thanks for your advice,

Can you send photo for device to know how it's look like

elameed elaneed · Mar 8, 2016

hello again
one of my friends give me one gearbox to me that is good news to me
i opened it and remove solenoid to check Resistance , but this time with two type of device to make sure about reading, but i founded different on reading i do not know witch one is correct ?

first reading:

second reading:

The Mad Hat Man · Mar 8, 2016

resistance = 1 ....... open circuit (not connected across)
resistance = 0 ....... short circuit (connected across)

for example... a wire will give a short circuit (reads 0), leads kept apart (reads 1)

Actually i will ask electrical engineer about this, because i don't have enough information in electric
In your experience, can you tell me witch read was perfect,and this soloniods good?

If the meter readings are 0 ohms with the leads touching each other, the meter is likely more accurate than one that is showing 1 ohm when the leads are touching each other.
For complete accuracy, the meter needs to be calibrated and certified as such.

That's mean second reading was perfect

Sorry for late
This is reading for ECU
