If your clutch pedal action feels normal, then your clutch mechanism has failed. If your clutch has not yet been replaced, you will likely get it replaced under warranty. This is a common and frequent failure on these cars. I am currently on my 4th clutch and currently having a performance clutch manufacturer design and build a high performance clutch for me so that it is ready to be installed when this 4th clutch fails.

 

 

The clutch is not fully releasing. The only reason you can shift once the car is rolling is that the synchronizers are able to assist the shifting. (if you rev match between gears, you don't even need to use the clutch pedal). This is how 2 of my previous clutches failed. Don't drive around too long like this, as your syncros will wear out prematurely.

Fixing this requires multiple parts, not just clutch.

 

In case no one has mentioned it yet, your clutch is failing :/

That was failure mode #2 for me. Failure mode #1 was slipping under load. Neither was consistent.

The thread mentioned by SinF has all the info. Somewhere in there is the service campaign number as well. That proved useful to me. I don't have the number offhand though.

When they pulled out the clutch, there were loose pieces. They ended up replacing pressure plate and disc, plus flywheel. When they pulled the flywheel, they decided to replace the rear main seal too.

 

For those who have had problems with the clutch, how many miles did your car have at problem onset? I'm not sure whether I've got the first or second generation clutch, but I've not had any problems with it yet and I'm at just over 1000 miles

First two failures on the Gen1 clutch, third on the Gen2 clutch and currently using the 4th generation OEM clutch. All within 22k miles.

 

I drive mine daily, so I rack up many commute miles. I complained about it when I had an early oil change (~7000 miles) but it didn't fail hard until much later. Initially, it would occasionally slip under hard acceleration, but not often enough that I could get it to happen at will.

 

My initial clutch was slipping at 0km and was replaced due to that. Second gen clutch lasted about 14K km and ended up damaging gearbox and differential. Third generation clutch is in the car right now along with a new gearbox. The rest is TBD, but there is now a forth generation clutch.

 

 

8000 miles with no problems. I accelerate like a bat out of hell whenever I enter the freeway.

 

I don't understand how this didn't show up during the development process. These failures aren't occurring at high mileage, and are way too common. They have to have known this would happen and yet, they released this setup for production anyway. It doesn't just make sense...unless, as someone posed earlier, they did it to provide a mechanical fuse to protect an equally-underspeced rear differential. Post-1983 Corvettes have always had higher-spec differentials on manual-equipped cars, and before that, all Corvettes had manual-spec-duty differentials. If Jaguar didn't realize that need on their own, wouldn't their transmission supplier have mentioned it to them?

If they didn't want to do the job properly, for whatever reason, why did they do it all? They had to have known that there was never going to be a high "take rate" for the manual. It's just baffling...

 

sounds like a problem with the clutch discs disengaging

 

To be fair, I accelerate like that... everywhere.

But I'm not abusive on the clutch. I almost always engage at idle or just above and THEN punch it. I did do a 1st gear tire-smoking launch one time though, but that was a while back.

Agreed, it is pretty frustrating. I am holding out hope that they've fixed it with the 4th gen, but Unhingd's posts have dampened that somewhat. Time will tell, I guess... I would not have bought an F-Type if they didn't make a manual, so I'm glad they did it, just hope they can make it right!

 

 

You driving it to your Bingo! games doesn't count as harsh use :P

 

As far as I know MT and AT have exact same LSD. Also, there aren't any flex disks anywhere in the drive-line, so as far as I know nothing is damping hard shifting.

If anyone is inclined, bang shift your car for a couple laps, most of your differential will drain out with oil.

 

This may be the source of your failing diff and tranny. Bang shifting through the turns is the fast way into the tire wall, not the fast way around the track.
