Transmission Temp gauge Install on 03 Pathfinder

[erubash]

Anybody have any ideas where I might put the NPT on my 4wd SE? Im towing a RV to New York next month and want to make certain I have real time trans temp.

Where to mount it?

Are you thinking temporary or permanent mount?

Why not just buy a cooler for the same price as a quality gauge and feel safe, instead of WATCHING it grenade digitally...

How heavy is the RV?

I second adding an auxiliary transmission cooler, as large as you can afford and mount, and perhaps installing an in-line filter; either spin-on mount, or an in-line filter such as a Magnefine. If you'd like you could also install a temp gauge at this stage, but placement is also something to think about - if you put it on the return line from the cooler you'd obviously have a misrepresentation of the true temperature. Ideally you'd get the temperature from the cooler inlet line (which I believe is the fluid coming from the torque converter, which generates the most heat). Doing this along with regular drain & fills around 15-30k and occasional pan drops to examine the pan magnet and replace the in-pan "filter" (which is really just a screen, and could be measured not in microns but in mashed bananas).

I have installed a B&M 70268, rated at 13,000 BTU, in-line with the stock cooler as well as a Magnefine in-line filter. I rarely tow, and when I do it's nothing very heavy (generally a small U-Haul trailer or a jetski). I do not have a temperature gauge and my generic scan tool can not read the transmission temperature (that is, if 2WD models even have an in-pan temp gauge; I'll need to look for one next pan drop at 150k), but for my needs I think I'm doing as much as I can to help the longevity and performance of my transmission. I plan drain & fills every 15k, currently using Valvoline MaxLife (synthetic) with no issues.

A member on NPORA has posted a basic guide on installing a trans temp gauge and spin-on filter here if you're interested.

Thanks for the quick replies guys: What I want to do is what "Fossilfuelburner" did from the nissanpath forum

The trouble I am having is where to insert the sensor within the transmission. My understanding is that the Pan the where the hottest fluid is. Once the fluid enters the valve body, gets used and therefore hot, dumped into the pan then out the cooler. But on my 4wd I can't find a place to put the sensor. Does anyone know where I might put it.

The Trailer is a 22ft Dutchmen weighs about 4200lbs dry.

I think I just found the pressure test port for Drive,2nd and 1st Gears. I believe it's located the passenger side just above the pan??

What happened to everyone, I got a bunch of posts then it's like the internet died? Please reply Im about to get after this bad boy and I need some questions answered from all you pros.

Thanks

I found a test port on my 97 qx4 on the driver side of the pan, just above the top of the front wheels driveshaft. Its a 12mm bolt, very short, so youll need a bspt extension piece..
