To add further to the CVT transmission debate I highly recommend reading an article found in Gears Mag. Written by Sean Boyle. Now the articles are titled JATCO CVT and Daimler Chrysler, but this doesnt mean it has nothing to do with Mitsubishi. Remember Its a known fact that Chrysler and Mitsubishi have shared techonlogy and approaches for sometime now. Furthermore, JATCO makes transmissions for these two manufacturers as well as Nissan about a decade, maybe longer. The CVT design for the SRT Caliber line should be almost if not exactly identical to the one found in the Mitsubishi lancer. So hopefully after reading this, it will add to the speculation to the CVTs boost potential

and the conclusion to this article can be found here in part 2

After reading all that, it should give everyone a better understanding of what is actually going on inside the CVT. And I hope give a new level of respect with that enlightenment in terms of the CVTs potential

 

Good video about it here second video down.

Wow, that was enlightening... After reading both parts, I'm thinking that the CVT can take high loads of TQ, just as long as you keep up on the maintance of fluid flushed every 30k and inspection every 15k for fluid level... And as long as you can keep the CVT cool under high TQ loads... Being an M.E. I would suggest a CVT cooler that is designed for double or triple the cooling capacity. Running stock I think your good, but running a turbo set up, redundancy is key to keeping the CVT cool under load, which means safety... I'm interested to hear what RRM's CVT cooler specs are, and how much redundancy they have built in to it...

 

there is something in the works but it is in the hands of some of the guys from Japan and Singapore so I am unsure what the update is. But it should work to reduce the temp further. Its a overkill option for only those who are running a extremely aggressive boost set up. Until you meet the cooling specs its not recommended to run your car in D mode, (that is under aggresiving driving conditions, if you just driving to the store and back or making casual drives you have nothing to worry about.)

There are temperater readings from the enhanced powertrain I beleive that will reveal the temp. of the CVT. I am sure the RRM cooler knocks of some critical degrees and allows the tranny to run cooler. Its a recommended upgrade even if you dont have a boost setup and your run your car hard. Heat is really the only thing that can kill the CVT, its a pretty tolerant transmissions as it is.

 

people had been boosting their CVT Altima's

I would think we should be okay, its the same technology right?

 

JATCO makes trannies for Mitsu and Nissan so yes same basic design.
