Hybrids and CVTs: Nissan RE0F03H (JF019E) - Transmission Digest

Hybrids and CVTs: Nissan RE0F03H (JF019E)

Sponsored by ATSG

The Background

Beginning with the 2017 model year, Nissan introduced a hybrid version of the Rogue with the RE0F03H CVT transmission behind a 2.0 L engine. Infiniti also produced a hybrid version of this transmission in the QX60 behind a 2.5 L engine. The Jatco designation for this transmission is the JF019E, which is a part of the CVT8 family of CVT transmissions. 

The RE0F03H has the typical primary and secondary pulley system that is belt driven. It also has a forward and low reverse clutch. What is unique about the RE0F03H? The electric traction motor in the front of the transmission contains Clutch 1, which is a dry clutch. Well, what’s so unique about a dry clutch? A dry clutch means that the internal combustion engine can drive the vehicle through Clutch 1 or Clutch 1 can be released. This then disconnects the transmission from the engine and now the traction motor will drive the car. Over at ATSG, we think that is pretty dang cool. 

The RE0F03H is available in two-wheel drive or all-wheel drive configurations. As is the case with all CVT transmissions, it is imperative that the correct fluid is used. In this case, we require the Nissan NS3 CVT fluid. Transmission fluid capacity should be approximately 6.25 quarts (5.9 L) and if it is all-wheel drive, the transfer case is a separate fill. This requires 0.625 pints (0.55 L) of the GL-5 80W-90 hypoid gear oil. 

What Am I Looking At?

As seen in the photos, the Nissan RE0F03H has orange cables coming out of the top of the transmission. These connect to the high voltage hybrid system that operates the traction motor seen in the front of the transmission. On the side of the transmission is the electric oil pump that supplies cooling oil to the traction motor when the internal combustion engine is shut down. 

On the other side of the transmission, you will find the fluid oil warmer as well as the Clutch 2 oil temperature sensor. A case connector for all internal electrical components is held in place by a circlip. Finally, when you remove the top cover, you will see the 3 phase cable terminals, U, W & V. 

We want to keep you safe! 

As with any high voltage system, the technician MUST take the proper precautions to avoid serious injury. Working with hybrids is a very different experience than other transmissions, so we are here to help! If you have no experience with hybrid vehicles, we strongly suggest heading over to atsg.com and checking out our “Resources” section. Here you will find a hybrid safety requirements document. Below we’ve put some great tips to keep in mind before working with a hybrid vehicle 

  • Be sure to ALWAYS keep an eye out for the orange and blue cables. These signal high voltage, meaning you need to take extra precautions. 
  • Before going near any high voltage components, locate and turn OFF the high voltage battery “disconnect switch.” But wait! To be safe, wait 15 to 30 minutes before touching anything.
  • Use a CAT III voltmeter to verify that the voltage level has dropped to 12 volts or less.
  • Never assume the vehicle you are working on is not a hybrid. It may be appear to be ordinary at first glance, look for common identifiers of a hybrid! 
  • Make certain the vehicle ignition key is off. This ensures the engine doesn’t start when you aren’t expecting it
  • Many more hybrid vehicle safety tips over at atsg.com! 

Procedure for Safe RE0F03H Vehicle Repairs

Now that you know all about the necessary safety measures, lets get into the actual procedure for safe vehicle repairs. 

1.     Locate high voltage battery disconnect plug

2.     Pull service plug lever and release lever locking tab

3.     Rotate green lever outward and pull service plug to remove 

4.     Locate 12 Volt battery in cargo area next to high voltage hybrid battery (see image)

5.     Disconnect 12 Volt negative battery cable 

6.     Remove inverter cover and verify across high voltage terminals 5 volts or less
