Was wondering how to find which CVT manufacturer is used in our model. Are all Rougue CVTs from Jatco?

My 2019 SV model has VIN starting with J...so I know this is made in Japan but not sure what CVT was used?

1) We have an incredible SEARCH feature on this forum. The answer is there if you look for it.

2) DO NOT create multiple threads asking the same question for different model years. I'll give you the benefit of doubt that you're new on how to ask questions, because you're bordering on being banned for spamming.

3) I cannot stress this enough, --------> READ BEFORE CREATING NEW THREAD! <--------

ALL Nissan CVT are Jatco.

Every NISSAN CVT is Jatco, due to a long relationship between the two companies (and Nissan did own Jacto for a period of time). However, other brands, are using Jatco transmissions (Subaru, FCA, etc.).

Thanks. Wondering how the 2nd Gen Rogue Xtronic CVT is different from the recalled CVT in some of the 1st Gen models. Or what was specifically improved by Jatco to fix this issue. I am just getting worried about the Jatco CVT (with all the bad rap around).

Trust me, I was in your boat for the past 3 years because this was my first CVT vehicle. I think they realized that they messed up somewhere in the design and engineering of the transmission. If you drive carefully do and keep up with the transmission maintainence (D&F the CVT fluid every xxk miles) you should have a long lasting transmission.

At least in the latest models they have started adding some standard automatic trans engineering to make them last longer, it lowers the constant moving around of the chain on the pulleys which is most of the bad CVT issue. The problem with CVT is that the chains hardly bite into the pulleys at all and normal, both are hardened metal and hardened metal to hardened metal wear is one of the bugaboos of long life in mechanical devices. The norm is soft on hard but that won't last in a CVT application. Another flaw is having to use 800 psi oil pumps, the pulleys require tremendous amounts of oil pressure to work. 800 psi oil pumps wear out much faster than 200 psi ones do. The pulleys due to that pressure require ultimate bearings and Nissan has had trouble with the bearings going bad there.

Thanks. I was looking for the specific design improvements on the 2nd gen Xtronic model but could not find anything so far but will continue to search.

Meanwhile I think the 2nd gen Rogues use the model# Jatco CVT8 JF016E or JF017E....a relevant thread:
jatco-cvt7-and-cvt8-t585534.html

Also, found this interesting analysis report for all CVT makers (looks like from 2016):

https://www.marklines.com/en/report_all/wsw0019_201607

I was just derping around online when I found this pretty neat resource regarding the list of Nissan CVTs: https://www.wittrans.com/catalogs/2018-WIT-CVT.pdf

It lists which vehicles has what CVT models, and has breakdowns of even the pulley system which I believe is not even found in the TSM. Hope someone finds this useful.

Folks, I'm not sure if this application is correct, so YMMV. As always, I found it on the web... it might have been true at one point, but that date and time are unknown...

Looks like my '16 Rogue may have the CVT8 / JF016E

Technical issues and repair guidelines

The valve body of the CVT8 unit has a reduced number of valves. The torque converter lock-up zone was expanded,allowing to improve acceleration and fuel saving characteristics, but on the other side the lock-up clutch wear-out leads to rapid contamination and necessity to repair the torque converter.


Repair procedures

During the first years after release of the series, Jatco engineers adjusted the TCM settings in such a way that they allowed loading of CVT components to the limit to attract potential buyers with enhanced acceleration dynamics. Therefore, the valve body replacement may occur during the warranty period. The design of JF016E components is very similar to the JF011E unit. Thus, it is expected that this CVT will be “invincible” on vehicles with engines up to 2.4 liters and that CVT on Nissan Murano with 3.5 liter engine will frequently appear in repair services.

During the first years of operation, repair specialists have to replace the oil filter-cartridge. This filter-cartridge is installed in the heat exchanger and maintains the "right" fluid level in the pan. Cone bearings are considered to be another vulnerable place in this CVT as in its predecessor. Bearings for the next JF017E modification were significantly improved. Problems may occur with the pump JF016E- 017E, which has fewer components in comparison with JF011, but operates as intensive as its predecessor. This CVT is also sensitive to contaminated and overheated transmission fluid.

Another thing to know if your nissan was made in Japan, Korea, or Tennessee.

I prefer Japan or Korea, because I personally think that Americans are more lazy than their asian counterparts. Hence, lower craftmanship.

I don't know about the newer models, if it matters where. But it seems the driving assistant technology or brake assisting gadgets are a pain in the a$$ for some members here.

Easy to tell from the first VIN digit, Casper:
J = Japan
K = Korea
3 = Mexico
1 or 5 = US/Canada

Note that Nissan has a plant in Canton, Mississippi as well as Tennessee.

Shimokawa [30] explored ways to improve the Jatco CVT8 transmission. To accomplish this Shimokawa reduced the lubricant level and added an axial baffle. When the axial baffle was added to the CVT8, the effect of the clearance between the baffle and gear face was not considered. Instead, the effect of the extent of the area covered by the baffle was explored. In the investigation, the area of the gear face covered by the baffle was varied. It was discovered that if the lubricant level was high, baffles that covered less of the gear face caused lower mechanical loss. As the lubricant level was decreased, baffles became more effective as the area of gear covered was increased.
