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
