Clutch Slipping on stock A91 MT...

[6mtsoup]

I have around 4500 miles… I’m partial unlocked with intake downpipe Chargepipe and OTS aggressive tune from BM3…. I give her sauce often the only time I feel loss of power is when I don’t turn off traction control and the car goes hey buddy we are spinning…. Once VSC is off so are all the bets… car been driving fine…… DOESNT MEAN I won’t upgrade my clutch though

9,500 miles now, stock. Similar to above, no issues unless traction is on, which is obviously tc kicking in. Enjoyed my first 1200 miles but didn't beat on it too hard. Been ripping it and slamming gears occasionally, spinning 1-3, no issues at all. Knew how to drive manual, have driven manual before, but first personal manual car. I'll think about upgrading my clutch when I start doing power mods

Stock?

Yeah, the car is stock. I only did downpipe, chargepipe, catback, and a intake. The brake in i basically babied the car for the first 2000 miles around town and highway driving. After the 2000 miles I started to beat on it occasionally on the highway or curvy roads. And the track I took it to for the hpde event was Carolina Motorsports park. I was going to schedule the hpde event Toyota gives us but seeing how the car performed and that there is no aftermarket or oem replacement for the clutch I’m holding back on beating on it any further since I don’t want the car sitting in a dealer lot waiting for parts.

so not stock

I wouldn’t say not stock since all of that is more of a placebo effect for added sound. That adds basically no hp at all without a tune and the car isn’t tuned. The main issue the clutch had was it can’t deal with the constant heat of a full day at the track, this happening with stock power or extremely close to stock power.

No issues here… but those that are having issues, should remove your CDV. Remember these cars were abused by a ton of journalists prior to delivery, they were not easy on the manual.

those having issues, please post A video for everyone’s sake.

That sounds great, do you have an intake or do all the MT have the little BOV noise?

you would need an open intake for a louder sound similar to mine, you will have much prominent "blow off" or turbo noise stock compared to auto since your interrupting air flow when shifting. to also answer some other questions i was tagged on, im running SP1R exhaust, is an 5 inch titanium single exit, the widest to my knowledge, so its very very loud.

Did you notice more exhaust burbles when you installed your intake? I wasn't expecting that at all but after installing the MST v2, in between shifts I'm hearing what sounds like a deeper exhaust burble as well as the "sneeze" from the pressure release in the intake. Maybe that's just because the intake isn't blocking as much of the area around the turbo/downpipe though.

This is even in normal mode where there shouldn't be many burbles. I've yet to hear it from the outside though so it may be something else. It just wasn't a sound I expected to hear from an intake install.

As far as the clutch goes, it does seem like this is becoming more common now. If it becomes widespread, I'm sure Toyota will eventually issue a recall. Otherwise, aftermarket options or swapping to whatever they use on s58 setups would probably work as well. I haven't looked into it but I'm guessing the b58 and s58 flywheel/clutch setup should be fairly interchangeable.

Ultimately clutch issues are annoying but not a huge deal. Once aftermarket parts become available they aren't very expensive and are a relatively easy job to replace.

I have the first track day in my MT coming up next weekend, you guys have sure put the anxiety in me, but I'll report back with what I discover afterwards. It bewilders me that Toyota would spend so long developing this transmission after the car's release and it fall short like this. Also how none of the reviewers who drove it on track/hard prolonged driving brought anything up about a slipping clutch.

I have a A91-MT w/ 1.6k miles. I find that for daily driving, I have no problems with the clutch other than the intelligent downshifting where sometimes it will not blip the throttle at all (not related). However, once I'm above 70-80% throttle, the clutch sometimes will freak out on me and I don't feel it engaging properly. I'll get like a buzz in the shifter and the car jerks and I completely let off the throttle. I've owned multiple MT cars and have not had an issue like this before. It's not like I'm abusing the car either, treating it the same as every other MT car I've owned.

I'm really thinking of moving towards a C8 / AT M3 or M4 at this point since I already have my FRS w/ a MT and am starting to get annoyed with this MT. I really really enjoy driving the car regardless so I may just be patient for an aftermarket solution lol

edit: mods include catless dp, intake, charge pipe

Has anyone confirmed there is/removed the CDV yet and tested afterwards?

Wondering if maybe the CDV delays the clutch a bit too much and the extra slip in high load situations it causes it to overheat. A clutch is a really difficult thing to mess up and I'd be really surprised if Toyota went with one that can't even hold up to the cars stock figures. Having to budget for a clutch replacement early in the cars life is pretty absurd.

Is it also maybe possible that Toyota got a run of bad disks or something from the manufacturer?

FuzzyRev85 is working on it. I can almost guarantee there is a CDV though. It feels exactly like my previous BMWs.

Regardless of the clutch slipping issue, I'm going to be removing mine when the part that contains it becomes available to order easily. It vastly improves clutch feel and smoothness in the 1-2 shift assuming you're familiar with driving manuals.

I had an M4 prior to this, although it was auto, there was some issues with the manual. Prime example, a select few were throwing out their clutch. BMW never did any recalls and those that had issues often had to fight to good will the replacement. It was just not loud enough for them to care. I suspect the same for the Supra MT. There’s realistically only roughly 1000 MT roaming around, and even if everyone hop on this train it wouldn’t be loud enough. CDV and traction control and a little bit of placebo effect is really turning this into a bigger issue then I think it is.
None of you complaining has any videos showing “slip”, not hard to do especially when your crying for Toyota to give a hand out. And let me just go head and be a player hater here, the ones complaining can barely type a proper annotation on a forum, owns lambos and has a hard time coughing up 3k. Not naming no names but they were also offered solutions via local discord server… all you coming out the wood works with 0 proofs sound like a bunch of clout chasers. Toyota ain’t gonna care, record your video proofs, act like a good dude and they might good will you. Bottom line is, everyone here paid good money for a manual, some more than others, I spray WD40 in my butt cheeks every time I get in mine because mark up. Don’t let this be the reason your pushing a Honda again, those that claim I’m GoNnA GeT iN BEtTer car, no u ain’t, relax. Turn off traction control, drive the mf to redline, and record it. If you actually slip, maybe then there’s a better conversation for the masses. Dont @me, I’m sensitive.

Looks like Clutch Masters just dropped their clutch kits for the MKV: https://mailchi.mp/c1cb95297de3/dsg-audi-quattro-owners-rejoice-17034711

Do you even English? If its a design or manufacturing fault Toyota should cover it. Simples.
