Is transmission Oil cooler necessary for 2014+ 5th gen Altimas? Tranny Safe mode

Is transmission Oil cooler necessary for 2014+ 5th gen Altimas?

Now there is one i think installed by factory which looks like this i think?

https://www.nissanpartsdeal.com/parts/nissan-cooler-asmy-aut~21606-28x0b.html?Make=Nissan&Model=Altima&Year=2014&Submodel=Sedan&Filter=(2=QR25DE;3=25S;4=CVT%2fQR25)&Location=pd:311_A001,21606X

Anyone ever had an issue in summer tranny going into safe mode, not allowing you go faster then 40mph in 2014 5th gen nissans?

Is that the symptom of tranny overheating due to cvt fluid cooking?

I inspected cvt fluid and it's not black, burned, it's light golden color. Granted it's not blue or green but it's also not black. Level is perfect spot on.

Why does this oil cooler look way different (no fins) then the one pictured in schematics? Which one does 2014+ factory installed have?

Anyone running after market tranny oil cooler in 2014+ years?

Necessary? More recommended than required. The latter would have Nissan in a fit of lawsuits afterall.

If it was my car, I'd seriously consider doing it as one of the best forms of preventative maintenance for a CVT.

Can you tell me again your car it is a 2014 Altima is it a 4 or 6 cylinder?

Take a look at these two links:

1) Link showing 2014 Altima Sedan, Transmission search --- https://www.nissanpartsdeal.com/Page_Product/SearchByName.aspx?Vin=&Make=Nissan&Model=Altima&Year=2014&Submodel=Sedan&Filter=()&Keywords=Transmission+Oil+Cooler+Service+Kit
2) Link showing Tranny Parts Diagram -- https://www.nissanpartsdeal.com/Page_Product/SearchByName.aspx?Vin=&Make=Nissan&Model=Altima&Year=2014&Submodel=Sedan&Filter=()&Keywords=Transmission+Oil+Cooler+Service+Kit

From what I see there are two parts you are dealing with in regards to what is part of the CVT -- One, the Paper Filter Cartridge call out 31726M, and call out 21606X the square heat exchanger with 4 tubes. The other part of importance in servicing the paper filter is the O-Ring call out 31526QC.

Now as for the EXTERNAL Trans cooler that would mount in front of the radiator/consensor behind the bumper/grille. Next, Let's see if we can find you one----??

OK... I did not see a OEM Transmission Oil Cooler ("External") in the a search of Nissan Parts Dealers. On ebay there are several aftermarket coolers here: https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=New+Transmission+Oil+Cooler+fits+Nissan+Altima+2014&_sacat=0&LH_TitleDesc=0&_osacat=0&_odkw=New+Oil+Cooler+fits+Nissan+Altima+2014

I would stay away form the ultra cheap ones (like Hayden) The ones from LinesRacing have sturdy looking coolers and that run from 9 Rows up to 28 rows of cooling tubes!

LinesRacing coolers are also sold over on Amazon. They use AN-10 fittings which work well especially with braided hoses. If you look at the ebay listing scroll down to see pictures of the cooler and the specs.

Hope this helps a little bit?

While I cant say I have ever seen limp mode with the trans. I have seen trans oil temps hit and hold around 290-300* after 1-2 hours of straight driving at 90 in 105* temps in Texas.

Add Transmission COOLERS? I say yes!

:surprise
If I lived in the Southwest I would for sure install a transmission oil cooler!

Fact is I live in KY and I just bought this one (see pictures) to install to hopefully extend the life of my 2010 CVT that already has over 100K on it, and has had zero issues.

Now... I was able to buy this Nissan OE Service Kit from a dealer on line which fits the 4th gen 2007-2012 Altima 2.5.

I looked but did not see a Nissan Service Kit for the 5th gen Altimas on any Nissan Dealer sites or ebay or Amazon? So I guess the next option is to buy an aftermarket transmission cooler.

Here is one link I ran across.... these guys have all sizes (from 9 row up to 28 row) and these coolers have AN10 fittings which is pretty cool!
9 Row: https://www.ebay.com/itm/9-Row-10AN-Universal-Engine-Transmission-248mm-Oil-Cooler-Kit-Fits-Nissan/172612696326?fits=Year%3A2014%7CModel%3AAltima%7CMake%3ANissan&hash=item283084b906:g:XiYAAOSwhQhY5W0G:rk:22:pf:0

I would suggest that anyone who wants to give your transmission half a chance in the summer heat to go ahead and install a cooler --- even the cheap ones are better than nothing. Not sure if it would CRASH your warranty --- so beware of that!

Shouldn't matter, Having Cooler much better than Not Having Cooler.
