Can a CVT transmission be rebuilt? Yes, and here is when it is worth it

Quick answer: yes, a CVT transmission can be rebuilt. Transmission Digest calls CVTs “quite simple” transmissions; the real obstacles are parts availability and parts prices, which is why many shops replace them instead. Before any rebuild, check whether your car is still covered by a factory CVT warranty extension.

Written by Mark Dannunzio, co-owner and ASE-certified lead technician at Shift Masters Transmissions in Phoenix. Mark and Ken and their team rebuild every type of transmission, CVTs included, and a 2013 Nissan Maxima CVT they rebuilt in 2019 is now at 140,000 miles with no complaints.

(Walks on stage. Trips over a drive belt. Waves anyway.) Regular readers know Gary, the transmission from our transmission rebuild cost guide. Today we meet his younger cousin Kevin, a CVT with no gears at all and a lot of opinions about it.

Kevin is whining, shuddering, or just acting strange, and somebody told you CVTs can’t be fixed. That somebody was wrong, and probably also tells people you can’t reheat pizza.

Rebuild or replace a CVT? How we decide

These are the rules Mark and Ken and their team follow when a CVT comes into the shop.

How does a CVT work?

“Unlike a traditional automatic with a set number of gears, a CVT often relies on a belt or pulley system to provide an infinite number of gear ratios,” says Consumer Reports. In plain English: two pulleys change size, a belt runs between them, and the ratio slides smoothly instead of clicking from gear to gear.

(Kevin does not shift. Kevin glides. Kevin will tell you about it at parties.) That smooth slide is great for fuel economy and terrible for anyone who misses the feeling of a gear change. It also means the belt, the pulleys and the fluid between them do all the work, so when one of them gets tired, Kevin lets you know.

Can a CVT really be rebuilt?

Yes. Transmission Digest, a trade magazine for transmission shops, put it plainly back in 2011: “CVTs are not complicated transmissions; in fact, they are quite simple.” (Simple for a transmission, that is. Please do not try this on your kitchen table. I can barely get the lid back on a jar of pickles.)

The proof is in our shop. We rebuilt the CVT in a 2013 Nissan Maxima in 2019, and it is at 140,000 miles and still going strong. More on that one below.

Why many shops won’t rebuild CVTs

“The biggest show stopper basically comes down to two obstacles: 1. Parts availability 2. Their prices if the parts are available.”
Wayne Colonna, Transmission Digest, 2011

Parts are the big one. A Nissan dealer technician on Reddit explained that with Nissan, “they don’t make the rebuild parts available for sale only for internal use,” so for some models an outside rebuild simply isn’t on the menu. (Kevin, it turns out, has an exclusive tailor.)

Then there is the computer. Transmission Digest notes that “CVTs usually will require a reset to the basic factory programming after repairing a major component.” A shop without the right tools can’t finish that job, so it says no. That is fair, and far better than saying yes and hoping.

What does a CVT rebuild or replacement cost?

CVT replacement quotes usually run $3,000 to $8,000 for parts and labor, according to CarParts.com, partly because many units are sold only as complete assemblies. (I priced a few for research and had to lie down for a bit.)

A rebuild depends entirely on what failed inside and what parts your model needs, which is why we quote it after the diagnosis, not before. For national price ranges on every kind of transmission job, see our transmission rebuild cost guide.

Check your factory warranty before anyone opens it

This is the step most people skip, and it can save you thousands. Several carmakers have stretched their CVT warranties well past the normal term. (Yes, I am a transmission shop telling you to go to the dealer first. My accountant just felt a disturbance in the force.)

Nissan: extended CVT coverage from 60 months or 60,000 miles to 84 months or 84,000 miles on 2017-2018 Altima, 2018-2019 Sentra, Versa Sedan and Versa Note, according to a Nissan dealer bulletin.
Subaru: extended CVT coverage from 5 years or 60,000 miles to 10 years or 100,000 miles on several 2019-2020 models, including Legacy, Outback, Impreza, Forester and Ascent, per a Subaru service bulletin.
The catch: Subaru’s extension does not apply to CVTs “overhauled, remanufactured or rebuilt by parties other than those approved by Subaru.” Rebuild first and you can lose the coverage.

So if Kevin might still be covered, call the dealer first. If he isn’t, call us.

How to keep a CVT alive

Use the right fluid, every time. Nissan’s own bulletin says to use Genuine Nissan NS-3 CVT Fluid only and warns: “Do not use Automatic transmission fluid (ATF) or Manual Transmission fluid in a NISSAN CVT, as it may damage the CVT.” (Kevin is a picky eater. Feed him the wrong thing and he will make it everyone’s problem.)

Consumer Reports says the same in fewer words: “Make sure you use a CVT-specific fluid, or you’ll risk big headaches (and repair bills) down the road.” Our transmission fluid change and flush service checks the fluid first, so you only pay for what it needs.

A warning light plus a strange feel from the transmission is worth a call, not a wait.

Know the warning signs, too. The Nissan CVT class action described in CarComplaints said affected cars would “judder, shudder, clunk, jerk and experience acceleration problems.” If Kevin starts doing any of that, he is not being dramatic. He is asking for help.

A CVT we rebuilt, 140,000 miles later

A rebuilt CVT can keep a car on the road for years.

We see CVTs from every make, with no single brand stealing the spotlight. (Kevin has a big family.) One we are proud of is a 2013 Nissan Maxima, rebuilt in 2019. In Mark’s words:

“Rebuilt a 2013 Nissan Maxima in 2019, the customer is at 140,000 miles and still going strong with no complaints!”Mark Dannunzio, co-owner and lead technician

That is a CVT, rebuilt by an independent shop, still going seven years on. Every CVT that comes in gets diagnosed first, and every rebuild carries our 3 years or 36,000 miles warranty on parts and labor.

CVT rebuild questions

Can a Nissan CVT be rebuilt?

Yes, when the parts for that model are available. A Nissan dealer technician on Reddit noted that some Nissan rebuild parts are kept for dealer use only, which is why the answer depends on your exact model. We rebuilt a 2013 Nissan Maxima CVT in 2019 that is now at 140,000 miles.

How long does a rebuilt CVT last?

It depends on the quality of the rebuild and how the transmission is maintained. The 2013 Maxima CVT we rebuilt in 2019 is at 140,000 miles with no complaints.

Is it worth rebuilding a CVT?

Often, yes, if the parts are available and the case, belt and pulleys are not badly damaged. If they are, a replacement unit is usually the better call. A diagnosis tells you which.

Can I use regular transmission fluid in a CVT?

No. Nissan, for example, says to use Genuine Nissan NS-3 CVT Fluid only and not to use automatic transmission fluid, as it may damage the CVT. Always use the CVT fluid your manufacturer specifies.

Will an independent rebuild void my CVT warranty extension?

It can. Subaru's 2025 CVT warranty extension does not apply to CVTs overhauled, remanufactured or rebuilt by parties Subaru has not approved. If your car might still be covered, check with the dealer before anyone opens the transmission.
