Hi, My frontier has 147K miles, frequent engine oil changes.
Noticed some stumbling and cutting out on the highway. No idiot
lights appeared. I checked the tranny, dipstick was bone dry. I am
assuming this is an all electric transmission and there is no vacuum
module? I have not seen leaks anywhere, it is parked in a garage
every night. I did do the transmission fluid drain and refill with
Matic S from the dealer about 5 months ago. How can I tell if I am
using fluid? Anything I can check for? Suggestions appreciated.
Thanks,
David

David,

Did you follow the Method to check the ATF that is in
the Frontier Service Manual?

When you did the ATF Drain and Fill, did you measure
the amount drained out and put that same amount back
in?

You are going to need to crawl under the Truck and
follow the Transmission Line's and try to see if there
is wet spot's and the redish Color NissanMatic S. You
may be getting leakage around the Drain Plug or Pan or
somewhere along the Line's.

You can check the ATF Level useing the Cold Range
before driveing, By letting the Engine Warm up to
operateing Temperature, then with engine running move
the Gear shift lever through all the gear's, return the
gearshift lever to Park and with engine still running
check the ATF DipStick. This will be a BallPark Level.
To get the ATF to the Correct Level,, The Truck needs
to be driven until the ATF Temperature get's to at
least 149F Degrees, then go through the same procedure
as checking in the Cold Range but now read the level in
the Hot Range. The Service Manual says to Check the
Dipstick when the ATF Temperature is at 149F Degree's.

If you don't have the Nissan Factory Service Manual you
can google and find a free download. I purchased mine
from:

reliable-store.com

for 10 $'s so I would have my own and not depend on a
Website to get access to the Service Manual.

I got tired of guessing when the ATF Temperature was at
149F Degree's, so I got a Scangauge II for my 2013 V6
AT Frontier. I'm in the process of getting mine in a
location that I can see the Scangauge II's Screen. I'm
going to put mine on top of the Dash in the Little
Tray. I'm waiting on some Extra Velcro that I will
line the bottom of the Tray on top of the Dash and
route the wire's in a nice way (Hopefully) useing Stick
On Wire Clip's. I did put in the Code's that Scangauge
gave me to set up the Scangauge to read the ATF
Temperature and it did show the Temp's in real Time. I
just hope that the Temp's Displayed are accurate.

But before I get ahead of myself,, You need to check
with the Scangauge Folk's, they have a website that you
can find by googleing and they will be able to tell you
if the Scangauge II will work on your 2008 Frontier; I
think it will but you need to check with them to be
sure; they are Very Helpful and Easy to talk to.

Probably the Safest thing for you to do at this point
is to put it on a Flatbed and take it to Your Preferred
Dealer so that they can check it out and make sure that
the Auto transmission is still serviceable. It probly
is if it has not been contaminated with Coolant which
is Known by Nissan that the Nissan Radiator's in the
Year's 2005 to 2010; a lot of the Radiator's in that
Year Range had a defective seal that would fail and
allow coolant to mix with the ATF. Hopefully this
hasn't happened so that's why it needs to be checked
out by the MasterTech at the Dealership.

You can also read about this Situation by Googleing
Nissan Frontier Defective Radiator's Mixing Coolant
with the ATF. Nissan also put out Bulletin about this
and Extended the Transmission Warranty for V6
Frontier's with AT in those year's.

Please don't let what I've written scare you, cause
it's one of those thing's that many did not know about
until it happened to them.

That's my advice for what it's worth, and I hope You
the Best and Hopefully it's just a minor issue that can
be rectified without any damage done.

It's just not like it used to be 20 year's ago. I just
changed out my Battery and used the EZ Red MS4000 to
keep the system energized so that the Computer Module's
kept their memory's so that they wouldn't have to
Relearn Idle, Brake's, etc.   

Regards,

Thanks for the info. I neglected to mention that I already replaced the
radiator with an aftermarket one since I had heard of the radiator atf
fluid contamination. Also. The check engine light came on last night,
waiting for my friend to come over today with a code reader.

David,

Well that's good, so hopefully you dodged the ATF
Coolant Contamination.

How are the Battery Terminal's Looking; Are they
Corroded? Are the Cable's Tight on the Battery
Terminals? Gotta start with the Simple Thing's 1st and
Neglected Corroded Battery Terminal's can cause a lot
of Problem's that can get Expensive Fast with the
Computer Module's. One Fellow I read about not too
long ago had to replace his ECM because of Neglected
Corroded Battery Terminal/Cable's. That's a different
Problem than an Extremely Low ATF Level, but you
mentioned the Truck was Cutting Out, which could be
interpreted in more than 1 way ie Engine or
Transmission.

That's another Thing that the Scangauge II can do as
well, display the DTC's as well. Last I checked Amazon
had the Lowest Price on the Scangauge II's.

Nowday's I consider it a MUST to INVEST in Basic
Electronic TOOL's for us Do It Yourselfer's to at least
have a General Direction on how to proceed with
Diagnosis.

It's just not like it was 20 year's ago.

Please keep us in the Loop as We All Want to know how
it is going and What it's going to take to get Your
2008 V6 with AT back to Dependable Driveing Condition
again. I sure hope it's something Simple and
Inexpensive which is Why I try so hard to do the
Preventative Maintenance on my own Machine's.

Regards,

So I hooked it up to the obd 2 scanner, indicated a trouble code for
camshaft position sensor. I was able to clear the code, took it for a test
drive mixed city and highways, no issues and and no check engine
light. Is this a warning that it may fail in the near future? Are frontiers
prone to this issue. p0340 was the code.

David,

OK, but what did you do about the ATF Level, and how
did you go about Checking the Level? You shouldn't be
driveing the Truck until you get the ATF Level figured
out and if you have a Leak,, but You know that anyway.

You can google the P0340 DTC and then research it
online. You can also wait here till someone come's
along that can give you more information on the
Camshaft Position Sensor. You can also do a posting
over at: nissanforums.com in the Frontier Truck
Section. SMJ is somewhat the Guru over there,, but
there are other's as
well. SMJ said that he worked for Nissan as a Master
Tech for about 16 year's but don't quote me on the
specific's.

Again does your Battery Post's have Corosion and are
the Clamp's Tight?

You need to get access to the Nissan Factory Service
Manual as it may help you figure this out as well. I'm
not a Professional Mechanic,, but over time I am able
to learn quiet a bit about my own Vehicle, by reading
the Service Manual, Reading the Nissan Truck Forum's,
Talking with the Nissan Service Manager, and with
Nissan Tech's when I am allowed.

If you are going to diagnose this Yourself,, You are
going to have to Read, Study, get the Tools and/or
Electronic Tools so that you won't be Driveing Blind so
to speak, Read Reread, and Study till you get a Grasp
on what's going on.

I believe I remember several other owner's with that
Crankshaft Position DTC, but I don't remember enough to
say anything about it. I'm just starting to get up to
speed about my 2013 (After Driveing a 1993 Nissan
Hardbody for 20 years) and I've been studying about it
since I got it 6 1/2 years ago. I've told you about
the 2 Electronic Tools that I've recently gotten, the
EZ Red ms4000 Memory Saver and the Scangauge II. As
time goe's by I imagine I'll probly get more Electronic
Tool's as the need arises.

Keep us updated Please,
Regards,

I added just under a quart of matic S dipstick reading is in spec for
both hot and cold.    Battery clamps are good, no acid and battery is
just under a year old. I will watch it carefully over the next week or so,
both the check engine light and tranny fluid. I do have a the shop
manual for this truck and followed the directions for the fluid change.

David,

That sounds Good David.

Sounds like the ATF was almost about to touch the
Dipstick, so I don't think any damage was done to the
Clutch Disk's, unless you were Drag Raceing or
something of that nature, so I think that is good. At
least I feel much better about the Transmission now.

That's Really good that you have the Nissan Factory
Service manual. I don't understand everything in the
Manual,, but I understand the Maintenance Section in
that it make's sense to me.

Good Just keep a close Eye on the ATF Level and maybe
check it more often now,, and if it hold's good then
less often till you are convinced that the level is
holding.

I'm pretty sure that the amount of ATF between the Low
and full hash mark's is about 8 oz. I'm still trying
to figure out the exact amount,, but it isn't much.

The Crankshaft Position Sensor may be what is causeing
the cutting out as you said in a Previous Post. I
don't even know where it is located, but I've read
where other's have changed it out. UTube may have a
video on how to change it out. I learn a lot from
UTube Video's. One that keeps comeing to mind is how
to Grease a Sealed Bearing, and if you've never done
it, it is actually real easy to do once you see someone
else actually do it.   

Something else that you may or may not know about is
the Timeing chain Manufactureing Problem in the 2005-
2010 V6 Frontier Years. From reading about it,, the
Engine will start makeing a Whineing Sound, but not all
the V6 Frontier's in those year's had the problem.

I'm thinking you've got a handle on your current
problem now.

Let us know how it is going,
Regards,

Hello, so some 300 miles later I got code p0340, so I will
be replacing the cam position sensor. Does anyone know if
its the driver side or passenger side sensor? Is bank 1
the driver's side?

Thanks in advance.
David
