You probably need more than a cooler. Nissan had some issues with the 2016 Altima CVT transmission slipping and released a TSB concerning the TCM (reprogramming, if I remember correctly) and replacing the subset, if damaged (the steel belt and pulleys). This requires removing the transmission and teardown along with having the CONSULT III tool to reprogram it.Just got back from a road trip, construction site both directions, 90 degrees outside, 45 minutes to go 6 miles. Has anyone installed a trans cooler? Nissan part# 21606-ZX59A? Thank-you, Nick 2016 2.5 Altima.
You might want to check into this cooler installation:It wasn't the response I was hoping but, Thank-you for the response. Found it, TSB NTB15-084b. Looks like nothing preventative will be done until a code. I have been looking at other Altima's and quite a few are well over 100K, so I would like to install a cooler on it. With the exception of going over the mountains, (2.5) this is the best road trip car I have ever owned. The cooler I mentioned is for 09-18. Nick
Cooler won't hurt, but don't forget to service the CVT fluid regularly. That seems to be a key on making these CVTs last. I would service the fluid at least once every 30,000-50,000 miles.
The fluid has two great enemies, and temperature is only one of them. The other is shearing force generated by normal operation of the belt, which increases on hills or with a load. This gradually breaks down and shortens the long-chain molecules that cushion the belt. So unless you drive like grandma and live in Flatsville Flats, 50K is too long. Keep it to 30K and the tranny will treat you well. Don't mess with the filter under the beehive, Nissan doesn't recommend ever changing it even if the beehive is replaced. The reason is, CVT's have almost no clutch material and never make "ATF soup" like a conventional A/T. So the filter's primary purpose is only to catch fine metal particles that get through the front pump instead of settling out in the pan. Changing it incautiously or back-flushing the system (never do that!) can both put those particulates back in circulation. You'll be better served to simply drop the pan every couple-three changes and clean it out.That is what I am getting ready to do. I am at 28K. So far all I have done is install a dipstick so I can have a reference. It has a filter and a screen but all I have found is change fluid at 30K, 5 qts. I believe.
You're most welcome. There's no big advantage to the order either way, but the top (return) hose to the radiator on an Altie is a complete PITA to access. Putting the cooler (or H-valve and cooler) between the beehive and radiator makes the installation much easier because the upper hose can be left alone. Note that on all side-tank Nissans, the beehive inlet and outlet are easy to identify. The bottom hose at the radiator is always the outlet, the top is always the return. Nissan does it that way deliberately, so the buoyancy of any bubbles coming out of the front pump helps chase them up and out of the heat exchanger and back to the beehive.Now I am trying to figure out flow and mounting orientation. Some say trans-cooler-rad, others say trans-rad-cooler. Mounting is the other, some say mount with fittings vertical some horizontal.
