All new Corolla with CVT transmission being recalled in the US to have the transmission replaced.

Even Toyota cannot make a reliable CVT

Beware

They’ve been making reliable CVT gearboxes for many many years now, in fact Toyota CVT’s rarely go wrong if scheduled fluid changes are followed. In this case a new design has quickly been found to be faulty and Toyota has acted to solve the issue rather than trying to duck their obligations. I’m not going to hold it against the firm and from the description of what has gone wrong I don’t think there’s a fundamental problem that’ll be ongoing now they’ve redesigned it.

new Corolla CVT - Engineer Andy

According to Scotty Kilmer on his YT channel, whilst the official recall is only affecting a few thousand non-hybrid cars in the US, he is saying that Toyota are, in fact recalling by the back door many, many more (including the hybrids) of the new Corolla by listing very similar changes as TSBs or similar.

At least I suppose they are doing the work, rather than sweeping it under the proverbial rug, like some German manufacturers have done of late...

A properly set-up CVT is an excellent gearbox-even Ford ones were.The problem is that few are set-up properly-garages take too many short cuts!

My reading of the problem is that the fault lies in the torque converter, not the CVT part.

I cannot understand why there is such a prejudice against CVT transmissions.

Early CVT’s were pretty awful things. I remember being horrified by my first shot of a Volvo 340 CVT ditto the jerky and noisy Fiat UNO, Ford Fiesta and Escort CVT’s in the 80’s and 90’s. The conventional Mitsubishi autos we were selling were vastly superior in every way except initial performance and certainly economy.

Now that HAS thrown me.

It's the first time I've heard that the transmission of a new car has to be fettled in some way before delivery to the customer.

What exactly has to to be calibrated or adjusted or whatever else is required to get the transmission to function correctly?

You can place a fair sized blame at the door of motoring press here. They seem to really have it in for the CVT, despite evidence to suggest that none of the hacks have driven a CVT for some years. That being their going on about 'mooing' noises. This is something i could well imagine being the case with older CVT's like my Dads Daf 55, with their infinite gearing, but the 'stepped' type, like what is in our Jazz?, not in my experience. Yes, it like to rev if you want to accelerate, but that has nowt to do with it being a CVT and everything to do with it being a n/a rev happy, torque light, 1.3. In Honest John's review for the Yaris, which has the same type of transmission as the Jazz, he state's it to be one of the best automatics, CVT or otherwise, available in a small car.

Early CVT’s were pretty awful things. I remember being horrified by my first shot of a Volvo 340 CVT ditto the jerky and noisy Fiat UNO, Ford Fiesta and Escort CVT’s in the 80’s and 90’s.

I was too young to have driven my Dad's Daf 55 (and don't actually remember much about what it was like to travel in either), but when i spoke to him about the Daf not too long ago, he remembers it being a great little thing to drive. Very smooth, comfortable and refined (compared to other similar sized cars of the time (circa 1975). He found the front seats so comfy, when the Daf died, he removed them and fitted them to his next two cars, a MK2 Escort estate and a Hilman Hunter. It also had exceptional traction, having seperate drive to each rear wheel!.

The DAF was lighter than the 340 and later Renault engined variants were surprisingly quick off the mark. The transmission was acceptable for its time in the lighter DAF but in the 340 it just didn’t work as well and it was up against much more refined rivals especially by the mid 80’s.

One of the biggest issues with them compared to a normal auto was the lack of any creep while manoeuvring at low speed. They were often awkward to control on the throttle and most used examples had seen plenty of minor paintwork.

The management at our dealership would buy in any small autos they could find. Margins were better as fewer people wanted them and you’d have less competition as fewer dealers bothered with them. They were at the time seen as pensioner mobiles only and the type of buyer was usually well to do and happy to buy without negotiation.

Believe it or not first genuinely good CVT I remember was the K series Rover Metro 1.4. These were much smoother than rivals and actually quicker and more economical than the manual equivalent. It could give a hot hatch of the time a b***** nose to 50mph. They never really went wrong either and drove brilliantly. Shame they never rust proofed them properly. The 1.4 GS was a lovely little car with wood vineer, leather, electric windows and a sunroof. Rare today.

new Corolla CVT - Lee Power

In the late 90's I had a Rover Metro 1.4 CVT - it was certainly quicker then the performance figures Rover quoted & could indeed upset people in warm hatches of the lights.

The CVT box wasn't reliable, the one I had could only manage 12k miles between gearbox rebuilds - after the 2nd gearbox rebuild under warranty I got rid of the car.

Its put me of owning any auto ever again, unless it's a Toyota one.

Very unlucky. We never had any of them back but then most of them were bought by old buddies doing less than 5k p/a and usually they’d never see the angry side of 40mph.
