Got it installed today finally. Gets up to temp quickly and holds it. Does what it's supposed to, hopefully it will extend the life of the transmission.
Are you watching the factory "guage"? If so that's your problem. I use a scan guage 2 and mine warms up to 170* just daily city driving.Can you provide a picture of where you mounted yours? Mine came in today and I'm going to try to install it tomorrow. A location of where you choose to install it would be helpful.
To answer the question of why, I don't see the temp move on mine at all, unless it's towing or idling for an extended period of time. I would like for the trans to warm up at least a bit on my non towing days.
For reference, it is the exact opposite of you statement, the machine won't gain temperature any faster if you have a thermostat with a higher set point, it just doesn't open until the temp reaches the higher setting.I could be mistaken about the logic and if i am someone with more knowledge can correct me but here goes. The thermostat will not make the tranny run hotter, it will get it up to temp quicker, that is all. I think about this modification for the simple fact i hate the way my truck shifts this time of year. The “flair/slip” on cold mornings is absolutely driving me nuts. Once the temp climbs to at least 90/100 degrees (scanguage) its a different ballgame. Warmer weather its 100% a non issue. So if you live in the warmer climates or have a pappy foot it wont make sense.
Well just to clarify I wasnt giving you shit about it, just never understood why. Keep us posted on how the trans operates at the higher temps and how high will the temps get now?Lots of comments, I like good conversation so I will tell you the "why" as well as clear up some misconceptions.
1. I don't use just the factory gauge. I have the EZLYNK as well as a trans temp gauge i mounted on the dash (electrical gauge).
2. The Aisin is an HD application that is honestly overkill for this truck, which is why I like it. In addition, there are two transmission coolers on this truck from the factory. This leads to the problem and the "why" I did this...
3. The transmission would rarely get above 120 degrees during normal operation and would barely hit 140-150 when towing heavy unless I was really loading it up like up a hill or in heavy traffic. Even then it never broke 170 or so. The ideal temp for an automatic transmission to operate at peak efficiency is 170-180. You want to see at least 140 when the truck is warm. If the transmission temperature routinely operates "cold" it's nearly as bad as running too hot all the time. The fluid doesn't function the way it's supposed to, it never gets to the proper viscosity, and the engine works harder to spin the transmission all the time because of the thicker than intended fluid. Transmission oil, just like engine oil, is designed to operate within a specific temperature range. Running outside that range all the time on either end of the spectrum is bad for longevity and proper functionality. My trans, like many others with the Aisin, was never running warm enough to function properly. A solution promoted by Josh Chapman and others within the community was a thermostat that allows the temp to maintain a proper operating temperature. Every modification I do is designed around longevity and increased efficiency, which also yields better performance as a byproduct.
As to the comment about expecting the dealership to fix problem induced by modifications, I think anyone who has dealt with Nissan or any dealership knows they won't do it. That being said, any flaws that are inherent in the design (or a defect from the manufacturer) is a different story and I 100% expect those to be covered. Outside of that, I don't let dealerships touch any vehicle I own. I do all my own work on all my vehicles. If something breaks that I caused, I fix it myself with no complaints.
I think I covered it all, but please ask if there are more questions. I'm not trying to sell the product, I just like to show projects I do so others can see solutions for certain issues or just know what's possible.
I know you weren't. Trans.temps so far are hitting 145-150 pretty quick and holding rock steady. I have to hook the EZLYNK back up (my trans temp gauge is currently unhooked as I look for an adapter) to get exact temps over time.Well just to clarify I wasnt giving you shit about it, just never understood why.

How quick is quickly? I just took a 4 Mike round trip and when I got home mine was at 110 and its 50* outside temp right nowI know you weren't.

Does yours also have a weird "false shift" in second around 1600-1800 rpm while accelerating? When mine goes into 2, it doesn't seem like it goes in all the way, and then goes the rest of the way (and not very nicely) around that engine speed. Doesn't matter how hard the acceleration is...My transmission would never warm up and flares from 3rd to 4th no matter what. The dealership wouldn't help so I installed 165 thermostat on mine. It still flares 3rd - 4th. But once it warms up above 140 it shifts very smooth.
This particular thermostat allows some flow at all times to eliminate temperature shock.Anyone think there would be a problem in the winter time with the fluid staying in the cooler longer getting real cold and then getting dumped in the hot trans when the thermostat opens? I know that's how engines are but they are designed that way.
