Transcripts

now today we're talking about clutch

pressure control solenoid valve so let

me show you where that lives on this

vehicle and I'll also show you on how I

remove the battery and the battery tray

many many vehicles you may be able to

get access to this valve by removing the

splash shield and if you need a guide on

that include a separate link in the

description box below showing you on how

you can remove a splash shield now if we

look in the engine bay all the way down

here let's wait until the camera catches

up right here this is one of those

valves now this happens to be valve see

there's also valve a and valve B which

lives in a different part of the

transmission but nonetheless everything

that I'll show you today you can do the

exact same thing on any of these valves

now you can test this valve while it is

still attached to the transmission but

in this case because the working room

here is so small and I can give you a

very good angle with the camera I'm

first going to remove the valve place it

on the bench and perform the test there

but again you don't have to do this you

can still perform all of these tests

while it's still attached to the

transmission let me just show you very

very quickly and how I remove then got

access to to this valve and then these

are just two 10 millimeter and 10

millimeter fasteners this looks a little

bit bigger let me grab a 12

and then this is just a battery

hold-down

tray couple of 10 millimeter fasteners

and then there's typically a plastic

under tray this has that removed into it

now underneath the battery is the metal

battery tray so we have that's a ten

millimeter fastener two tens

these are 12s and then there's one

sneaking on the side here and then we'll

be able to remove this and get clear

access to all the sensors in fact very

quickly before we remove this valve a

couple of pointers I can give you if

you're not sure where the valve lives

and I say this all the time in other

videos but the first thing you could do

is a google image search for your

specific vehicle a lot of times you can

pick up diagram showing where the valve

lips option two is to purchase a repair

manual specific for your vehicle you can

typically purchase them for five ten

bucks get a PDF file something off like

off eBay for example option three is to

visit a forum that deals only with your

vehicle a lot of times you can find

someone on there that just knows the

vehicles inside and out but even if you

just do a part search for your vehicle

just to see what the valve looks like

you can start of start to decipher what

works what's right what it's not writing

that sort of thing so if we look at

everything here and just clean this up

right down here this is a pressure

switch but this obviously doesn't look

like the part this is the input or the

main shaft speed sensor that we showed a

few days ago just want to move this that

way I can

there we go here's the harness connected

down here for the pressure valve so I

press on the tab there we go and pulling

the body a little hard with one hand

there we go

move the wire harness as best as you can

and then if you look right here there's

one there's another one we're over here

- and two more underneath 10 millimeter

fasteners and then we'll just remove the

valve from the transmission

now once you remove all the fasteners

this comes right off it slid right off

in fact very very easy than that stick

nothing like that but also very quickly

I just want to show you there's also a

screen real hard to see right here

there's screen in there and we're going

to remove that make sure that's not

clogged up

right there we go

okay now this little valve controls the

flow of transmission fluid inside the

transmission now behind this the brains

of the system is the PCM or the power

control module so if you take a look

inside this valve there's a pump as a

motor in here or a solenoid valve that

moves back and forth and we're going to

test that if this does not move back and

forth the valve is completely shot you

need to replace it so a very very simple

operation in a sense this guy that we

remove this is known as the ATF feed

pipe what happens is if this starts to

clog up the screening in here you

certainly will have some symptoms they

could be a number of different things

you may have delayed shifts the vehicle

does not downshift in other words you

come to a stoplight and the vehicle just

doesn't downshift also erratic shifting

let's say it bounces from third gear to

second gear to third gear to second gear

that sort of thing and most likely you

will have a check engine light on the

dashboard so let's start by testing the

valve and also at the very end also take

a look at the harness connector that's

the connection that plugs into this make

sure that there's no dirt grime grease

anything like that because it will

affect the way that this valve is

supposed to work now the first thing

we'll be doing is in ohms or a

resistance test to do that you need a

digital multimeter this one I purchased

off Amazon does a terrific job it was

inexpensive I'll include a link in the

description box below if you do need a

multimeter you can do so many different

tests with this thing if you plan on

doing your own auto repair purchase one

of these - absolute a must-have now

taking a look at on the meter here you

have a number of different tests but the

one that we need is the Omega symbol

that is for a resistance or an ohms test

okay so the multimeter has two leaves a

black lead and a red lead taking a look

at the sensor here we have two prongs or

two pink connectors all that we're doing

we're taking one lead touching the left

and the other lead will touch the right

that's it now doesn't that matter if the

red touches left or the right vice versa

it doesn't make a difference just take

the leads to the sensor now to make this

a little bit easier I'm going to use

alligator clips again you don't have to

do this by any means and also don't

forget you you can perform this test

while the solenoid valve is still

attached to the transmission I'm just

doing this because for me to film that

would be very very very difficult oh

okay let's just clean this up so again

one lead goes to this guy now a good

valve should read on average three to

ten ohms is a pretty good reading if you

don't see a reading here the valve is

bad or if it's incredibly incredibly

high typically than the valve may be bad

but that being said we have thirteen

thirteen point four ohms that's

acceptable I'm let in that three to ten

on average but I'm perfectly happy with

that that doesn't concern me that much

but this is the first test the next test

is to test the valve now how do we do

that let me clean this up but again this

is the first thing you want to do to see

what the resistance is like now the next

test is to see if this valve moves back

and forth now how do we do that we just

apply battery voltage to the valve now

you can use the car battery for example

in my case I have one of these RC

battery packs that push out pretty close

to 12 volts so all that we're doing is

taking the power from here to the back

from the battery to the solenoid again

you can do this a while it's still

attached to the transmission no need to

remove it so here we go again alligator

clips this we have to be careful make

sure that these guys don't cross we

should have some let me flip this over

and here we go

okay hear that let's move this up now

I'm not sure if you can see that look

toward the top at the 11 o'clock

position see how that moves so this

verifies that the valve is working

correctly now if we do this test the

valve does not move your valve is bad if

you do this test and it's very very

sluggish then that's a very good

indication that it's going to go very

very soon the other thing you want to

check is the passages in here make sure

that it's everything is clean there's no

dirt grime oil anything like that at all

same with this little passage right here

make sure everything is nice and clean

now lastly when you reinstall this make

sure that you have a new gasket I do not

in this case I don't have a problem with

this valve I'm just doing a how-to but

it really should purchase another gasket

I just don't have one right now so when

I reinstall everything later on I'm

going to have to order a new gasket

because I don't want this to leak any

transmission fluid but those are the

main points check for resistance or you

could just jump right to this to the

battery test if you want to buy again

you should see that clear movement is

not sluggish nothing like that

whatsoever now when you're ready to

reinstall the feed pipe make sure that

the screened end is inserted into the

transmission so this is the screened end

on the other end it is not okay so

screening transmission okay

let's also check the harness connector

make sure it's nice and clean no oil

dirt etc and then looking at the harness

connector as you can see it's clear of

any grease grime oil you want a nice

clean connector

now when you reinstall the fasteners you

don't need to over torque these they're

only around 910 foot-pounds from the

factory so just give it a good snug and

you'll be perfectly fine there's no need

to put a lot of brute strength into

reinstalling this so as you can see

testing this valve is quite simple again

all of these tests you can do while it's

still attached to the transmission and

my kid is just easier removing it and

showing you how it all works if this is

something that helped you you're looking

for other transmission videos I'll

include a playlist that probably within

the next day or so I will have and on

that playlist will be other transmission

videos and maybe that we can help you

somewhere else along the line so that

being said thank you for watching we'll

see you next time
