Fixing GR Yaris Gear Miss Shifts | 4K

[@PIRASMotorsport]

Share your experience on mis-shifts and pitch stopper mounts, let's talk!!

[@panick.attack]

Great insights! Would never have considered how a part breaking can be so crucial.

[@PIRASMotorsport]

Yes, as I like saying, on cars like these, its easier to make it worse than better, looking at all aspects!

[@jasondoulkeridis6202]

I’ve been using the Cusco since 2021 and put 26000 very hard KM on the car with a lot of track events. I have even bottomed out the car on ripple strips and bent the cross member exactly in the middle where the torque mount fits, and there is zero deviation. It’s extremely good.

[@PIRASMotorsport]

I’m happy to receive your confirmation on this, thanks Jason ☝️🙏

[@Kirtanus]

as I mentioned on insta - i'm using powerflex racing line insert there. A bit more vibrations for me just adds sporty feel. Gear change is much more precise. I'm not too much confident with 4-to-5 fast gear change, but this is more to the huge hand move required, and here probably some short shift can help. Anyway such shift happens only once per lap on the main straight with my stock power engine, so does not affect lap time much.

[@PIRASMotorsport]

I heard about quite a few that are having the 4-5 gear change issue, but I never experienced it

[@richardmueller6322]

The inserts in the OEM torque mount together with inserts in engine and gearbox mounts completely fixed the issue for me. Torque mount inserts are from Whiteline, gearbox and engine from Powerflex (I believe). I do feel more vibration in the car, but got used to it. It is only in the lower rev range.

[@richardmueller6322]

Forgot to add, I use aluminium inserts where the gearshift mechanism meets the gearbox.

[@PIRASMotorsport]

Yes, I also have the aluminium inserts in the gearshift mechanism. Your setup is similar to mine, only difference is the aftermarket torque mount, as I have seen in the past that inserts wear over time. Thankyou for sharing!

[@holgerstoll4682]

Hi Adriano, I am sure the cusco works well. I have installed the airtec torque mount with the purple powerflex inlet. Works also very well. The vibrations I can feel, but it's o.k. The weight is higher than the cusco. I will see how long it works. The mean problem I think we have is when the motor and gear are hot, it comes from the front torque mounts left and right in the engine room. The rubber at high temperature lets the engine move between 5 and 8 cm. It's easy to find out when you deinstall the cusco middle torque mount, you have installed. It's 50% better but not perfect. Maybe you can find out and make a video about what's best torque mounts to install in the front. I know the powerflex inlets to put in the OEM torque mounts, but I have not installed them. Next engineering work for you😊. Regard Holger from Germany

[@PIRASMotorsport]

Hello Holger, thankyou for sharing! I already have the Powerflex Black inserts in both the engine side and gearbox side mounts, and they make a very good difference, at a price of much increased vibration

[@CarAndMechanical]

I'm quite interested in this and will be interested to see how my stock one looks - but I do have a question. I have an early GR collected in Jan 2021 and now on 22k miles and I've rarely had shifting issues, but on track occasionally messing up into 3rd (which if I'm honest I suspect it down to me). Did Toyota change something in their QA process/specs? As I mentioned I'll be interested to see what mine it like when I change it a little later this year and it's possible I'm just used to it...

[@PIRASMotorsport]

Hello, nice to meet you! I believe the early cars had the most difficult gearboxes, while the later ones were better. I hope they improved things in the Gen.2 but have no confirmation

[@wubziz4769]

Hi Adriano, great video once again! The torque mount was one of the first "mods" I did to my GR Yaris. I went for the purple DNA Racing one, very happy and no problems so far. For the upper engine & upper gearbox mount, I went with the yellow PowerFlex ones. Probably will upgrade to black ones soonish.

[@PIRASMotorsport]

Cheers mate! How many Kms do you have on the DNA? I have the blacks, very happy with them, but you do noticeably feel the added vibrations in cabin

[@Cernunn0s90]

My DNA torque mount worked great until it didnt. The bushings split down the middle after around 10.000KMs. No launches from 0, no track driving.

[@PIRASMotorsport]

There you go, thankyou mate for stepping up and sharing your experience! Just as imagined…

[@wubziz4769]

@@PIRASMotorsport I have roughly 5000km on mine now. The inner cabin vibrations went back to as it was with the original torque mount like 1 months ago… Makes me wonder if mine is also ‚dead‘. Are DNA products that bad?

[@wubziz4769]

@@Cernunn0s90 How did you notice yours was broken? Did you check it after some time or did you notice it through impacted performance when changing the gears?

[@TTTonyTurbo]

Im confused. Some websites say the cusco pitch stopper was made out of aluminum and others say it is steel. Are there different versions?

[@PIRASMotorsport]

You are right, I saw the same: fact is that some are WRONG! There is only one version, they should check their text better!!

[@dvim]

A year ago I tried the Airtec torque mount with the softest plastic insert. However the vibration inside the car were a bit too much since I daily drive the car. The vibration was especially prominent at a couple of specific RPM values, one around 3000RPM and then another at 2400RPM I think. When accelerating, the car would shiver at these RPMs and the whole inside would rattle. I was not impressed. :) Did you feel any increased vibration at a specific RPM with the Cusco mount?

[@PIRASMotorsport]

Hello mate, thankyou for the very precise insight! The biggest difference I feel is at idle, no changes thru the rev range. But I also have Powerflex Black inserts in engine and gearbox mounts… My suggestion is that if the NVH is very important for you, maybe it will be best to stay stock. Any mount will introduce increased vibrations. Good mounts will be more linear, but we have a 3 cylinder car, that is the most unbalanced engine possible

[@MiguelSanchez-hb9rf]

Are you saying you re-torqued it after each of 3 heat cycles? I had this part installed and the vibration was always terrible and after a few months I went back to stock mount with Whiteline upgraded rubber/neoprene insert. The original oem bush in my stock car was already ripped to pieces when i changed it after only ~5000kms!

[@PIRASMotorsport]

No retorquing mate, it is that you have to drive the car very hard, so it heat cycles the rubber from extremely hot to cool for 2/3 times

[@zion168]

​@AJClubsport Can't you just heat cycle the rubber part with a heat gun before installation? A noob question, sorry😅

[@zion168]

​@@PIRASMotorsport.

[@PIRASMotorsport]

@zion168 you could yes mate: on the other hand it doesn’t harm to let it do its process in place on the car…

[@SebastienBrunier]

Great videos, very instructive, but I'm sorry to say, in your office, seeing the Nords 24h layout mirrored on your wall triggers OCD sooooo much 😅

[@PIRASMotorsport]

Sorry mate, what is OCD?

[@SebastienBrunier]

@@PIRASMotorsport Obssessive Compulsive Disorders, it's a joke to say it triggers me 😂

[@PIRASMotorsport]

Ah ok 🤣😂😂😂😂 cheers mate! Nurburgring has given me many many satisfactions in the past!

[@lambrosstamos4494]

Cusco screams quality. Talking shifts and miss shifts, what about that CAE shifter that is very popular. It's not cheap, though.

[@PIRASMotorsport]

Yes, I haven’t got around to that yet. There is also another brand that makes a similar kit for a bit less, still looks good. Fact is, I am still figuring out what level to take this car to at the end of this journey!

[@grahamhaynes7658]

Verkline on mine,improved shifting,along with a short shifter,stock shift quality is poor and a low point of these cars imo.

[@PIRASMotorsport]

Yes it is, thankyou for sharing!

[@Sprintcup1]

Another great update AJ, good to see it's a steel construction, never understand Ali on a fast road car. I had mine into the dealers early on for adjustment after watching your early video on this. I was struggling to go from 1st to 2nd, but this would go after the oil warmed up. It came out a little more improved but the issue returned, I still get the odd clunk from 1st to 2nd as if it's a synchro, but once fully warmed up it clears. Do they do this part in black, hate these bright colours on parts, just attracts attention if your in for MOT or inspection, just me being old lol. Regards Russ....

[@PIRASMotorsport]

Yes, you have a point there: unfortunately this is the only color, but you can always spray paint it AND it won’t be seen if they don’t take the under tray out
