Aside from the flurry of funky new concept and production-ready cars revealed at the 2015 Tokyo Motor Show, Japanese transmission manufacturer, Jatco, has also taken the opportunity to unveil the CVT7 W/R transmission. Developed in conjunction with Nissan, said gearbox is slated for use in compact, front-wheel drive cars with the China-only Nissan Lannia scheduled to be the first recipient.
According to the firm, the W/R in the name stands for “wide range” with the transmission said to have been based on Jatco’s CVT7, which was launched earlier in 2009 – said gearbox was also the world’s first CVT with an auxiliary gearbox. As expected, the new transmission touts improved fuel efficiency and drivability.
An “active slip control” system is claimed to prevent excessive engine take-up response when setting off while the D-Step (Dynamic Step-Shift) control adds on to the sportier side of the driving experience. Also, a compact oil pump design, redesigned belts, “improved pulleys” enhance fuel efficiency by 3% and allow said transmission to boast the largest ratio coverage for a CVT of 8.7.
“The newly-developed Jatco CVT7 W/R represents a significant advance in eco-friendly technology and contributes to improving the performance and reducing the CO2 emissions of internal combustion engine vehicles. The new product will also be crucial for the Jatco group to achieve its goal of becoming the No.1 automatic transmission manufacturer in the world by 2020,” said Jatco president, Teruaki Nakatsuka.

Looking to sell your car? Sell it with Carro.
I want the GTR-like dual clutch inside my Vios
Toyota Vios still sleeping with 4 speed conventional auto, bro.
New one nowadays drink more fuel than an ancient 3-speed auto Wira. But don’t worry, they (UMW Toyotaik) put 2-speed auto (with only D and L position in non-CVT gearbox) in taik Vios with ridiculous high selling price also still got a lot of ‘tai lan ngong’ people to buy it blindly because of ‘T’ badge.
Lannia?
Nissan Lannia?
Hahahaha
Who need Jatco CVT when we have great CVT from Punch.
Proton- you are Punch blue black by their cheap low grade cvt. Proton has the habit of using the cheapest vendor. How to sell their product. Engine also using timing belt. High
maintenance cost. Hyundai cars are also using timing chain now. Wake up Tun. Don’t ever say the customers must pay higher for better quality Proton. Bull shit old technology.
Agree that Proton always cut corner with doggy deals and crony’s vested interest, hence the poor quality in their final product. However, using a timing belt doesn’t mean inferior, there’re many hi-tech engines that uses timing belt, can you say that EA888 is a bad engine?
Lol even best engine uses timing belt.
Proton.. please, please, please ditch the Punch CVT ASAP and start using these Jatco CVTs. I’m sure Jatco will be more than happy to work with your other vendors e.g. Siemens-VDO in refining the TCU maps and do all the necessary CanBus interfacing to make it a drop-in replacement for the Punch CVT, with minimal R&D and trial-and-error by Proton..
Agree. Those who say Punch CVT is fine has never driven a Jatco sourced Nissan. Heck, even Honda or Subaru CVT are miles better than the stupid Punch. Makes you wanna PUNCH it every time you drive it.
i can bet that proton top management don’t even have proton car at home. that’s why they never bother to change the whining cvt. money come first
Even if its compatible, building a car is not like building a lego. Its not plug and play. Homologation requires a lot effort even with full focus from both parties. The good this is, the engine is Protons, so it reduces the complexity of managing car pipu, txn pipu, engine pipu, ECU pipu, and others.
Proton will use Jatco CVT7 too due to rebadget Suzuki elerio in A-segment. Suzuki Celerio is using Jatco CVT7 too.
Hello everyone! Does anyone know how to strengthen the CVT on the Nissan juke turbo? Native digesting CVT max 320 N/M and 252 PS after program completion .
