Piston Slap: Justy-fied Freestylin' Over CVTs, Part IV

Hello,

I enjoy reading the piston slap series.

I have a 2009 Altima with the 2.5 4 banger and the CVT transmission. I’m not a big fan of the CVT, but it works ok and gets decent mileage. I bought this car as it was the cheapest car I could find that fits 4 adults and qualified me for the cash-for-clunkers handout. I didn’t expect to keep it long or pile the miles on it this quickly but now it has 90k on it. I mostly drive it without any passengers as we now have 3 kids and the minivan gets used for family duty (just had one kid when we bought the Altima). I’m trying to decide if I should hold onto it or sell it – it’s kind of at that point where if I keep much longer, I’ll probably end up driving it into the ground.

The transmission is the wildcard to me – is there a consensus whether these trannys can be expected to last for 150k or more miles? The trans warranty goes through 120k but by that point the vehicle probably won’t be worth a whole lot.

Sajeev answers:

That body style Altima was my favorite rental in its class for a while, its CVT was surprisingly on point. Compared to other manufacturer’s downright slothy 6-speed automatic transaxles, Nissan’s CVT (from 2007 and up?) was no slouch in any metric.

Even if the transmission fails right after the warranty expires, this isn’t an unobtainium gearbox like the Subaru Justy. Nissan’s been in the CVT game for years now, odds are they’ve spent millions investing in this future (including warranties). There’s a learning curve in rebuilding/diagnosing them, but (in theory) CVTs are fairly straightforward. This webinar brings a ton of valuable pros and cons of CVTs from the perspective of a local transmission rebuilder.

    The failure rate of the CVT in the Nissan Pathfinder and Infiniti JX is very high. For Nissan's sake, I hope all these hundreds of thousands of vehicles they have been selling lately do not have the same failure rate as those two, it would be the kiss of death.

    Those in the know, know... The BG machine would not be used in a CVT application; it's loaded with the wrong fluid, and the trans pump provides the pressure which is not a certainty in most CVTs I've seen. Drain, refill, and cross your fingers.

      Thank you . I didn't know but I *do* know to ask here as Forums are my friend.... Sooner or later I'll be faced with a CVT and this is the first time I've heard anything but derision and hate on them @ TTAC . One of my old Mercedes W123's has the hydro-pneumatic rear suspension and it can either be a royal PIA or a wonderful thing , as I routinely carry 7 people in it , I prefer the wonderful thing route and use Mercedes fluids in it because all problems always seem to begin with leaks and experience has taught me that hydraulic leaks are caused my lack of service and wrong fluids , in that order . Damage and wear comes long after . I hope the California Tree Hugging Thought Police don't arrest me for doing Routine Maintenance properly ! (sarcasm font is broken) =8-) . -Nate

  • FreedMike This is before Cadillac styling went full scale nutty...and not particularly attractive, in my opinion.
  • JTiberius1701 Middle of April here in NE Ohio. And that can still be shaky. Also on my Fiesta ST, I use Michelin Pilot Sport A/S tires for the winter and Bridgestone Potenza for my summer tires. No issues at all.
  • TCowner We've had a 64.5 Mustang in the family for the past 40 years. It is all original, Rangoon Red coupe with 289 (one of the first instead of the 260), Rally Pac, 4-speed, factory air, every option. Always gets smiles and thumbs ups.
  • ToolGuy This might be a good option for my spouse when it becomes available -- thought about reserving one but the $500 deposit is a little too serious. Oh sorry, that was the Volvo EX30, not the Mustang. Is Volvo part of Ford? Is the Mustang an EV? I'm so confused.
  • Mikey My late wife loved Mustangs ..We alway rented one while travelling . GM blood vetoed me purchasing one . 3 years after retirement bought an 08 rag top, followed by a 15 EB Hard top, In 18 i bought a low low mileage 05 GT rag with a stick.. The car had not been properly stored. That led to rodent issues !! Electrical nightmare. Lots of bucks !! The stick wasn't kind to my aging knees.. The 05 went to a long term dedicated Mustang guy. He loves it .. Today my garage tenant is a sweet 19 Camaro RS rag 6yl Auto. I just might take it out of hibernation this weekend. The Mustang will always hold a place in my heart.. Kudos to Ford for keeping it alive . I refuse to refer to the fake one by that storied name .
