Clutch Satisfaction

The shifter is not a "have to" update. The throw is shorter than my two previous cars, although longer than the one I updated with a short-shifter.
The delay valve is a different story. I don't notice it (much) in daily driving, but away from the commute and feeling sporty, it's a problem. I haven't had issues where the clutch just wouldn't engage, but I have adjusted my driving to account for the weak clutch. I shouldn't have to do that.

10-4 on the shifter - I dont want to overstate the case.
Don't really understand why this is a problem, the BMW M3 has a similar ZF 6spd MT & clutch (S6-37) as is generally considered 'bulletproof'. The F-Type has the slightly beefier version (S6-45) built to handle more torque, also used in the BMW 135i, 235i and 335i - where slippage does not appear to be a manifest problem from my limited google-ing. What gives, I wonder?

As a warning however; I have had horrible experiences with Spec's customer service, hopefully you guys don't experience the same.

I can't imagine the problem is w/ the gear box and almost certainly has to be w/ the clutch system.

I had an '08 E93 M3 with the ZF 6MT, which is a V8 w/ over 400HP, and it was indeed bullet-proof. I couldn't make it slip if I tried, and it was equal to the awesome Tremec unit I had in my C6 Z06.

Maybe the first 2 clutches on my car were pre-production units since mine was one of the first to arrive stateside. It would be nice to determine if there is an updated part number I could insist they install rather than having to do this at my own expense.

My car was scheduled into the performance shop next Monday to begin the process of having a decent clutch designed and built, so I took it into the dealer one last time this morning to see what they had to say. I went on the test drive with the tech to make certain that it was tested properly. Of course, he drove it like a sane person and commented that it felt fine to him. I asked him when he last drove a manual transmission and he gleefully remarked that he had driven his 2014 C7 over the weekend. I immediately chided him to drive my car the way he drove his. After the clutch smoke cleared, the car was signed in for servicing. Hopefully they can fix it and I can save $1-2k. I'll keep you posted.
Note: Despite the clutch issue, the tech expressed his desire to trade his car in on an F-Type. (just loves the V6 sound)

That tech sounds a lot like me.
After years of Corvettes and other big rumbling V8s, I now vastly prefer the exotic tones of the F-Type V6. After hearing the V6, feeling the perfect balance, and more nimble handling, I just wasn't interested in the F-Type V8. I've always preferred corner-carving to straight-line acceleration. I'm still thrilled w/ my decision after 2 years, and I'm still not tempted to go back.

No issue if that happens (and I wouldn't put it past them)...that's now just a 2 minute fix, thanks to the Volvo forum.

Thus, it would be the JLR "fix."

I'm certain they might try to use that as an excuse, but the CDV actually exacerbates the slippage rather than minimizing it. Without the CDV, the clutch now feels like it positively engages under moderate acceleration. Problem is, for me moderate acceleration is the exception rather than the rule.

OK...here we go again. Tech has decided to try a new clutch kit, flywheel and throw-out bearing. The catch is that the flywheel is on several months back-order...at the factory. Again begs the question where all the flywheels are coming from for production.
I still need to clarify whether they have updated part numbers for either the clutch kit or the flywheel. As we all know: "insanity is doing the same thing over and over again and expecting different results".

So far, after only couple days of unspirited driving I am happy with gearbox on my F-Type S. The manual gearbox was surprisingly comfortable in traffic. Shifting was smooth into all gears, catch point wasn't too deep or too narrow, making it easy to shift without focusing on it. Clutch pedal wasn't too light or overly stiff, but about right on the side of heavy. No problems going into any gears, even easily into reverse without having to pump clutch. The only complaint I have is reverse gear position - do not like it next to first.
I have driven 5+ manual cars over many years. My present winter beater is MT Subaru and its gearbox is outright soulless (but functional), so this might be coloring my impressions.
I yet to try push my Jag hard... all of the above is everyday driving impressions.

Since your car is a more recent build, it is possible that you have an updated clutch that resolves the issue. This is my hope, as it would resolve my problem.

*******s. So it is a band aid, they knew and released it anyway. The more I find out about this car, and company, the more I wish I'd gotten an old RX7 and an Edsel, or 3, instead...

They pulled parts off the line for you before, maybe they can be encouraged to do so again? (assuming they're fitting the new parts on the line of course!!)
