CVT Gearbox Help Needed 2013 1.6 Petrol

[stevem9]

Hi, I'm a newbie here and a, desperate.  My 2013 Auris 1.6 Petrol CVT gearbox has died.  Toyota want over £7000 to fix it (despite it having been serviced by them from new and always on time) which is WAY more than the car is worth.  I'm trying to get a secondhand box so I can swap the mech unit out of mine and install it but cannot find out what else shares the box.  There are loads of Hybrid boxes but nothing for the 1.6 petrol that I can find, nor anyone who'll rebuild my box for sensible money.  Anybody out there able to give me some pointers of I'll have to scrap a perfectly lovely car with 11 1/2 months MOT.  Thanks all

Welcome to the club. Sorry to hear this. First thing I would do is to write to CEO of Toyota UK. Hold Toyota responsible, and ask them to replace free of cost. It will be pretty hard to find one for petrol engine but check eBay as well. 

[stevem9]

Hi thanks for the quick reply, do you really think Toyota might help? The car has done over 130,000 miles.  I have been told by breakers there are loads of these in their yards with broken gearboxes as the repair costs on anything over 5 years old exceeds the value of the car.  I've also been told by a couple of independent repairers that the gear oil should be changed every 30,000 miles but Toyota say they only need checking every 60,000 and that's what they've done on the service documentation.  It had literally just had a full service and MOT (and advisories dealt with) by the dealer when the box went .

Hi, sorry to hear that happened. This expensive repair does not worth it if out of warranty. Warranty is up to 100k miles and I think Toyota may not help unfortunately. Is there any possibility to scrap the car through the insurance and pay the excess and whatever money you get to put into a new car instead? I don’t think it is a good idea to repair your box as it may be costly and secondly at that age and mileage more things can go wrong shortly afterwards and it will become a money pit car. If you like to go that route best to get in touch with independent automatic transmission specialist and ask for a quote or second opinion on that matter. Used auto cvt should be from exactly the same model if you want to try that too. 
Good luck 🤞

Unfortunately the Relax warranty only covers vehicles with less than 100,000 miles.

As regards the transmission fluid change, if the car has been serviced within the Toyota dealer network, Toyota's maintenance guidelines should have been followed. Doesn't matter what independent garages views are as regards frequency of fluid changes.

As an outside chance, you could try contacting Toyota GB (in writing rather than by phone), highlight the fact that the car has a full Toyota service history and was only serviced a few weeks before the failure, and ask whether they would consider making a goodwill contribution towards the repairs. Need to be polite and to the point.

Obviously, if they were to agree, the work would need to be done by a Toyota dealer.

Please come back to the forum to say how you've got on.

When you say swap the Mech is it a CVT or a MMT what is the issue ? Any codes ?

if it has the MMT toyota quote the clutch, flywheel, clutch actuator, shift actuator and TCM (gearbox ecu)

Not sure where 7k comes from as Toyota offer a remanufactured option original part number 30400-20020 and reman 30400-20020-84 which is £3789.89 +vat 

To be 100% PM your chassis number

[stevem9]

PMd you Devon.

It is a CVT and as I understand it you have to swap the unit otherwise the car will need reprogramming by Toyota (at exorbitant cost) and won't even start if it realises it has a different box.

[flash22]

Find a gearbox specialist that knows what they are doing

a CVT will be a K310 or K311 gearbox what's around £1500-2k for a rebuilt box drive in, drive out

anyhow, you need to get a second opinion (shock horror dealers aren't always correct) - plus they like to scare people

Is that all-in? Otherwise the difference to the OP's quote is probably labour. Off-menu (i.e. non-fixed price stuff) labour rates at dealers are very high!

 

That's a point tho', what's the issue with the CVT?

If they die, it's usually the belt snapping which results in a total loss of drive so the car can't be driven at all.

If it can be driven and there aren't any scary grinding noises the box is likely okay and it might be something else like a blockage in the control hydraulics or something..

No drive, first thing i would look for is twisted or torn CV boot as a drive shaft may have striped its spines, lose a shaft and the diff does nothing

 

[stevem9]

It lost drive pulling away at a roundabout, then got stuck in park.  Gearchange lever is very stiff (also disconnected from box to check if cable and it's the gearbox not the cable that has gone so tight can only move the selector lever on the box one notch (park to not park).

Where on earth are you getting the prices from, I have called a couple of specialists and they are quoting nearer £3500 plus VAT, others I have emailed who are advertising lower prices have not responded.  I can get the car to somewhere to get it done and it would be worth £1500 or so all in.  Can anyone tell me who to contact for these prices, preferably somewhere in the East Yorkshire / North Lincolnshire area but will travel if I have to for best price.

[flash22]

Did Devon confirm what box it is ? drop me a PM with your VIN

[stevem9]

PMd you flash

[stevem9]

Thanks Flash and Devon for your responses, that part number seems to be used on several Toyota models so I may have a better chance of finding a second hand one, I really am loath to write off the car if I don't have to.  I suspect the CVs are probably OK as I'm sure the dealer would have checked that first - wouldn't they??  I'll check when I can get under it.  Am I right in thinking I'm going to have to swap the electronics from the old box to the new for the car to work?  Is there anything else I should watch out for when getting a replacement box and fitting it?  Does ANYONE know where the gearbox specialists who do it for £1500-£2000 are as all the ones I've contacted are hugely more than this.  I'm near the Humber bridge but can transport the car (with a second mortgage for the fuel probably - or is that a third after the gearbox cost?) or could probably replace the box myself if I knew what needed swapping. There seems to be a good guide here Transmission repair manuals K310/K311/K312/K111/K112 Thanks again all who help

UPDATE.  I am today going to collect a gearbox and torque converter from a low mileage known good car and will hopefully be fitting it later this week.  Will post any further updates.

[Cyker]

Best of luck, let us know how you get on!

[stevem9]

Well, transmission and torque converter are out. bit of a nightmare getting it round the rear cross member so that's going to come off so it goes back in more easily and it was well stuck on one of the dowels.  Still trying to find out how to do the level when it comes to filling it with fluid.  There is a plastic bung as well as a filler so I presume that that may have been for a dipstick.  From what I can find out it needs 71mm of fluid in it when running and at temperature so will make up a dipstick.  Given there is no 'straw' in the sump of either the new or old transmission it would seem toyota must use a dipstick as without the straw the negative pressure method would not work.  Any suggestions welcomed.  Stage two, putting the new one in will be next weekend.

[furtula]

Saying it needs 71mm of fluid when level is kinda weird, have you checked owners manual for info about transmission oil?

Rule of thumb when filling up manual transmission was you fill in the top hole, until oil comes out, and should be level with the top hole, not overfill it.

Quick search online shows:

[Gerg]

In this thread about the iQ CVT, the unusual filling procedure on that box is evident.

Perhaps yours is very similar in it's filling technique?

 

[furtula]

You can also get a scale, measure the container empty, drain the oil into it, measure how much, then clean the container, and fill with same amount of fresh oil, which then will go into the transmission.

[flash22]

The IQ cvt is very different and is unique to the IQ as the diff and drive shafts are at the front

fill procedure is as per your own link above

https://at-manuals.com/manuals/k311_k310_k312_k111_k112/

fill it up run it through the gears check the level, fill level depends on if it's a new or old trans and how much you can drain as you will get some trapped in the passages and torque convertor, if it's a new TC you will have to run the gearbox to get the fluid pumped in to the TC

 

Here is the fill instructions

Bob, Many thanks but the two vital bits are missing (last page the Adjust Fluid Temp and Adjust Fluid Level links, nowhere does it say what the level should be!!) That's what I'm stuck on.  The transmission oil filler tube in the third and fifth images looks like the sump level tube (which is not there on either of my boxes) and the overflow plug looks like the drain plug to me.  The refill hole in images 7 and 8 makes more sense than filling through the bottom, so all in all I'm still not much wiser.  The box I'm putting in is a K312, complete with a 'new' torque converter.  Both are empty of fluid.  There is no instruction I can see in my link for filling and setting the level on a K312 box.  The old box and the new box both have the 'bung' circled in the picture but there is no dipstick.   There is a separate filler plug though which is why I suspect the bung is used for a dipstick 

  In the last picture you can see the rear subframe crossmember that when removed will make the box a straight lift as opposed to having to negotiate  and tip it past.
