Anyone else with fast shifting clutch issues?

[J_Maher_AMG]

That is exactly my experience. What I'll probably do is order the steeda spring and then just take the spring out when at the strip to get fastest shifts possible.

I don't particularly mind the two stage feel if it wasn't costing me half to a full second of non-acceleration at the strip. Granted, I bought this car primarily for road course, but drag is fun sometimes.

If you're having this issue it would be very unqise to be take it to the strip... there is something mechanically wrong with your car. I can shift literally as hard and fast as I want, without even coming 100% off the throttle and never experience any issues with the clutch.

Going drag racing with a known issue you are just asking to break something and have it denied under warranty.

The spring has absolutely nothing to do with shifting speed, it is the clutch pressure plate that is sticking and keeping your transmission disengaged causing the "revving".

it has been discussed how the clutch engagement is right at top of clutch throw rather than at bottom. Try not going to the floor with it.

It isn't at the top, but not at the very bottom either. You can barely come off the clutch and the car will start to creep ahead, stock spring definitely has a weird feel to it though, Steeda spring makes it much more linear and easier to feel the engagement point.

Steeda spring then never look back. Bite point of the clutch still feels lifeless with it but at least your leg/brain isn't trying to process the sudden change in force at the same time you're trying to feel the bite point.

For fast shifts obviously feeling the bite point is moot.

[MENTION=25497]rotisserie_gold[/MENTION] has a clutch spring delete in her Roush, whereas I have the stock spring in my 350.

Every time I drive her car I'm like "Jebus, this thing is stiff." But then after a day of driving it, the 350 spring, which normally feels fine to me, has that stuck on the floor feeling.

Conversely, whenever she drives my car, she complains about how light and springy it is, but then she gets back into the Roush and is all like "My legs are gonna look like crab claws."

While I haven't driven a standard S550 I disagree about not being able to fast shift the GT350.

I didn't actually say you can't shift the Tremec in the GT350 quickly. I said it isn't the greatest transmission for fast shifting.

The Tremec is FAR better at shifting fast, and LOVES to be shifted fast. It actually shifts smoother the faster you are with it.

The MT-82 has been known to not be able to keep up with the driver in regards to shifter speed. And the quick-shifting action of the new tremec unit has been mentioned in a number of reviews.

I had my brother in my car with me and was showing him just how happy the car is when shifted quickly, I literally donkey kick the clutch and hit the next gear, his comments were that it felt almost like a sequential gearbox in regards to the speed and kick it gave.

I've owned and daily driven 3 different MT-82 cars. From 2012-2015 that was basically all I drove. I daily drive my GT350. I've had two different transmissions in my GT350. I know what I'm talking about. People like to talk down the MT-82, but it's actually a very good transmission. Especially the 2015+ version of it I really enjoyed. The Tremec box in the GT350 is a really good unit as well and it's great for most everything. It's just not that great for fast shifting. On the road course there's no reason to try to speed shift anyway, so in my opinion the Tremec is fine for what the GT350 (at least some versions of it) is designed to do.

Not bragging, but I consider myself a fast shifter and my pedal stuck to the floor twice last weekend. Hit a gear, car revs like I missed a gear, double check engagement thinking wth, then bam the clutch pedal hits my foot. Needless to say, I've got a steeda spring ordered and am hoping for the best.

I've never had the clutch pedal actually stick down or the engine rev as you're describing, but the clutch pedal can't keep up with my foot if I'm trying to shift too quickly.

I agree with what you're saying if it's revving. The revving thing never happened to me. I do agree that a lighter clutch pedal assist spring might help the clutch pedal come back up more quickly. I tried the Steeda spring and I just didn't like it.

Hi OP I HAD that same exact issue when I put the steeda spring in so I took the spring out all together and still had the same problem after a few days of no spring I put the OEM back in and the pedal stick was gone. now the car has 6k miles on it and I don't have any issues
any one want my steeda spring shoot me a Ten spot and it yours

 

[sublime1996525]

The very first time I tried a fast 1-2 shift in the car I thought I missed a gear because of the slight delay in the clutch coming back up. It was a weird feeling. A Steeda spring is probably in my future.

 

[jpindustrie]

I had the same issue, I don't think its so much anything sticking like the pressure plate but more the 2nd half of that 2 stage spring kind of hanging up. I put in a Steeda clutch spring and the problem disappeared during hard shifts.

Also made it way easier during low speed maneuvers like in a parking lot.

 

[Venandakatra]

The pressure plate thing does make some sense. I'll have to check out how the spring is implemented on the clutch pedal as I could see it engineered where the spring is helping to push the pedal up when clutch is higher, and help push pedal down when it is lower. Theoretically a lighter spring could help if that is it.

If it doesn't work, I'll take it to the dealer, but I'm kind of nervous about your stereotypical dealer mechanic screwing up my car. That is the main reason I really want to give the spring a shot.

Already ordered one - I think you guys shipped it today. I was playing with the clutch tonight and quick drive to the store and back and felt/heard a clicking at the pedal. Wonder if that thing the spring sits on is a problem. I feel a little click in the pedal like right on the transition of the two "stages".

Weird, definitely shouldn't be hearing any audible noises when depressing the clutch. Perhaps the OEM spring setup or clutch itself has something installed incorrectly causing an issue. Can you identify the source of the noise?

Will check it out tomorrow. I had some work to take care of.

Out of the two B302's I had, both MT-82's sucked. Cruising is fine but if you wanted to grab 3rd quickly you could forget about it. Having to work around a transmission because of its shortcomings really sucked and sapped the pleasure of owning those cars.
