CVT Longevity


Recommended Posts

Good luck. You ruled out all the standard items.

 

 

Remember that Torque Pro, ActiveOBD, ActiveOBD Plugin for TQ, OBDWiz and OBDLink's own software ONLY ever deal with OBDII and E-OBDII data via CAN.... not SSM via CAN like BtSsm does. Entirely different protocol and data stream on the CAN bus.

 

Ironically this is where most of the useful information flows for Subarus (although in your relatively new Hitachi-based car, even more good data has been migrated over to E-OBDII... but not reverse engineered and defined). SubaruDieselCrew tried and got fairly far but gave up.

It was a service adviser, been there for several years. My question was then does Subaru recommend changing the transmission fluid? He said, "they are sealed, it doesn't even have a dip stick, no way to change the fluid and we only crack them open when there is a problem, otherwise there is no reason to open them up"

 

I came across a couple more sites, just in case you were interested ...

I am at 204k on my 2010 Legacy 2.5i with CVT. It has so far been trouble free for me aside from the issue with the Torque Converter which was covered under the Extended Warranty. When I bought the car I asked about it and they said it was a "Maintenance Free" transmission. One of these days I will do a simple change of the CVT Fluid (easy enough to do under the car). Otherwise I have no complaints. I had the TC replaced last year, at around 160k miles and have since put just over 40k on it with no issues. I drive a good 40k miles per year so reliability is huge for me.

 

Just traded a 2010 Legacy 2.5i with the EJ and the CVT with 232K on it, loved that car. Had the valve body replace along with the updated TC under extended warranty at 182K. Did fluid changed at 85K and 150K.
