I agree with Terry. The one from the factory is a good one to go with.

Our Pathfinders have a plethora of coolers. We have coolers for the transmission, engine oil, and power steering fluid.

I guess the real question is, do these systems required modification or augmentation? No real way to know without some pretty specific temperature information. Hard to make that analysis without Nissan's design parameters for the cooling systems, ie top tank temps, flow, heat rejection of components, etc... I've never found this info anywhere. Anyone have it??

Are there a number of people out there with overheating problems? If not, it's probably not something to worry about. I'll be towing 4000+ lbs in the AZ heat this summer so we'll see.

Is there a certain trim level that wouldn't have these coolers or do ALL PF's have them stock from Nissan?

Hello- I recently had my trans replaced this week and I was wondering if this

is the factory transmission cooler.

Please let me know if it is or not.

If I need to buy a transmission cooler can you guys recommend a good trans cooler for my path.

thanks,

thanks,

it is one of the two factory transmission coolers
was your transmission replaced because of coolant contamination of the transmission oil?
is your internal transmission cooler (in the bottom of the radiator) by-passed?
or was your radiator replaced?

it was replaced bc of the contamination and my torque converter was not working.

I did the following bypass

before the transmission repair. I haven't changed my radiator on my pathfinder the car does not overheat.

do I need to replace the radiator to avoid my transmission from messing up again?

do I need to put transmission cooler besides the one posted on the pic?

thanks for any feeback.

no, the only reason i can think of to replace the radiator is if you want to restore the internal radiator cooler back into the system.
under most circumstances, the external cooler is sufficient by itself (provided it was thoroughly cleaned and flushed of any and all contamination and debris from the original trans failure).
for heavy towing jobs, it might be a good idea to have the internal cooler, or add an additional external cooler.
there are many attempts and recommendations in this forum regarding additional aftermarket coolers and/or fans to enhance cooling (use the "search" feature).

where to mount an additional external cooler has been my big question!
two problems that i can see mounting it next to the one in your picture:
1) the power steering cooler is in the way
2) blocking air flow to the main radiator by having the additional cooler in front of the left side of the radiator
i, too, would like to know if there are any other solutions to this problem.

You're Welcome!

BTW: are you beyond the mileage for extended warranty repair for this situation?
if not, a dealer would have replaced the transmission and installed a new radiator...........

I'm installing a B&M Hi-Tek cooler 70297 tomorrow... will be taking off my Shrockworks bumper to install a winch and will be installing the additional cooler since I'll have the massive bumper off. I'll take pics of how I mount it. Stay tuned...

Following up to my previous post, I tried to add another external transmission cooler (B&M Hi-Tek Cooler 70297) while keeping the stock external cooler over the weekend, but as eieio and others have noted, there isn’t a whole lot of available space to add another cooler without moving/re-routing the power-steering cooler, horn, etc. Perhaps it’s possible with a smaller cooler, but the 70297 is the exact same size as the stock cooler and is the same design (fin and plate):

Anyhow, I ended up removing the stock cooler and replacing it with the B&M cooler. You could probably just add on a fan to the OEM cooler and save some money, but I like shiny new things and didn’t want it to go to waste. I didn’t have time to wire it up but that’s this evening’s project. I’ll post more pictures later…
