Clutch slipping after 2 months of ownership

[CULaterJimzo]

What did CM says the torque limit was for the FX250SS?

I emailed them asking what was the 250SS rated at, never got a response.
But according to Titan Motorsport (search FXSS250 clutchmaster supra) at the bottom said it's rated at 475Ft-lbs.

0 miles, I’ve only had the car for 2 months. I don’t know any driver that could kill a clutch in 568 miles haha

I've had my 2023 A91 since February and have had no issues with clutch slippage. The only issue has been the clutch pedal got a little squeaky soundin inside the car so I sprayed a quick lubricant because my ocd was kicking in driving me crazy. That's about it. It shifts like a champ.

Ok, check the simple stuff first. It will not go into gear with the car running, but can you start it in gear and it drive normally?

I assume there is a clutch safety switch that must be made. If so:

I'd check to see if the floor mat or some other object is preventing the pedal from going down enough to make the safety switch.

If that checks ok, then I'd check to see if the clutch safety switch needs adjusted. I've never worked on a Supra with a clutch, or owned one, I'm just trying to cover the simple stuff.

If the story that we are getting is true, that there was no issues, and all at once, one day there was an issue, I'm leaning toward something other than the clutch.

Someone else probably said it already, but I'd start with the slave cylinder for function and fluid. I'm not buying the dealer's diagnosis. In fact, I'd be more inclined to think that the dealer discovered a simple cheap fix, but sees an opportunity to rape an ill informed customer for a pay day. But that's just the skeptic in me and my lack of trust for all dealers.

Just an FYI side note, see this car? This one right here?

The original owner appears to have taken it straight to the track after taking delivery (I kinda love people that buy these to wring out like there's no tomorrow). History allegedly shows that it received four new tires at 1,800 miles, then four more tires at 2,200 miles...and then the clutch went kaboom at Road America, necessitating a clutch & flywheel replacement at...2,400 miles. Bravo!

Sub'd as I'm curious as to what the dealer discovers when they tear it apart.

Another MT owner here, 3K miles. Car was properly broken in and since then has done a lot of autocross and a track day, no issues with the clutch slipping. Though I do occasionally have an issue when shifting abruptly from 1st to 2nd, but I attribute that to the shitty CDV.

I'm much the same.. I have done around 3,000km with no slipping issues. And yes, that 1st to 2nd gear shift is horrible. I personally haven't seen any evidence to suggest it's the CDV other than the usual, "I always remove the CDV from my cars" argument.

My current car has a CDV and everything has been great for the past 15 years. ?‍

Yah fair, might not be the CDV. My issues always seem to happen when there's a fair bit of yaw and even a bit of slip angle when trying to make that hard & fast 1->2 shift. Doing it in a straight line there's no issues. So, it may be a momentary misalignment of the trans and the linkage, or maybe I'm pulling the shifter too far too the left and it's snagging a bit of the reverse lockout, or maybe the CDV or maybe a combination of any of those. But definitely no slipping.

I've been trying to isolate it but I can't. Quick/slow/under load/casual/straight line/in a turn.. it doesn't matter. Every now and then the car just hates on me and my shift is shit. And every now and then, for no reason at all, sometimes it just works perfectly.

For me it feels like I'm doing a lazy shift and ballsing it up but I'm actually not.. if anything I'm laser focused on making the shift perfect because I know its temperamental. And no, I don't think that's the reason why it's not doing its job 100% of the time.. which is literally its one job.

I can confirm it is the CDV. After I removed it changed my 1st to 2nd and made me feel like I was driving a traditional 6mt.

Seems unrelated... Toyota should cover it

Had mine since march, new. I've abused it, street raced, drove it daily. (femto, meth, tuned) clutch still held up perfectly fine. Had ordered the FX350SS from ClutchMasters along with their Hydro bearing. Fx350ss is definitely semi-aggressive, I don't recommend for daily but great upgrade for futureproof; I spoke with CM and I might swap it out for the FX250SS for the daily driven comfort. Other than that, just like previous comments, imho you still spend less than pure transmission upgrades, much cheaper route than Toyota/BMW.

Hydraulic Release Bearing and the bushing/pin clutch pedal kit well worth

What's the torque rating on the FX350SS?

Interesting. Is it 100% fixed? What I mean is, is that if you physically get the change right, does the car respond with 100% accuracy on the 1-2 gear shift?

I don't get the jerky 1st to 2nd shifts anymore. I grew up with manuals and am 39 years old so my CDV experience wasnt that of a rookie driver. The CDV delete was very obvious after I got it done with the 1st to 2nd shifts.

Cool. I may have to look into this further. My skepticism lies in that my Type R has a CDV and its shifts are great all the time.

 

[Stvee]

It's 100% the CDV. I know CDV implementations in other manufacturers aren't as bad but BMWs CDVs have always been terrible.

Can also confirm, since i install the hydraulic release bearing, its a substantial night and day difference shifting 1st to second
