I know this has been covered before, but I wanted to log my experiences start to finish in it's own thread perhaps to help someone in the future diagnose their issue, as the other threads are 8-10 years old, and the symptoms of each instance are not exactly the same to this one.

First things first, the car is a 2006 GS with 29k miles. It got a full clutch job with Hill Engineering T\O bearing, complete with tow to Maserati for F1 flush and PIS setting on 8/8/2017 at 28k miles. I've had this car for about 2 months now, and have put about 500 miles total on it. It also has the FD DBW, and is always driven in manual sport mode.

When I first got the car, I noticed that leaving from a stop, the more gas you give it, the clutch slips. The only way to get a good, minimal slip, takeoff is to blip the throttle and accelerate smoothly and very modestly until it's fully in gear. I made another thread "launching the F1 gearbox" or something to that effect, because I thought I was missing a trick to get it to launch more aggressively without slipping. I've since then begun to suspect that this may not be normal operation. It is worth noting that once the car is going, especially at high demand, the shifts are

Within the first 50 miles of driving the car, the second issue popped up, the transmission when shifting from 2nd to 3rd gear, would skip 3rd and go straight to 4th. After experimenting on the road with throttle demands while shifting, speeds, etc, I parked the car, and cut the battery while having lunch. After an hour or so, I fired everything back up, all was well, and never experienced the issue ever again.

11/19/18 Last night, 500 or so miles later, as I was driving home, I floored it in second, and the car seemed to have just the slightest reduction in power, and a faint smell of clutch afterward. The smell was so faint that I wrote it off as another vehicle, or just in my head because I felt like the car should have accelerated differently. 2 minutes later, it was parked in my garage, and I even went out after 5 minutes with the door closed to see if I could detect clutch smell which I couldn't.

11/20/18 This morning, leaving for work, started the car, backed out of the garage, everything seemed to be normal. About a mile into my 5 mile commute, the CC Failure light came on accompanied by beeps. There were no symptoms whatsoever, the car shifts normally. Stupidly, I thought it was the trunk indicator, so I completed my journey to find the trunk closed, and realized what the light actually was. It is worth noting, I did rag on the car once again in second, and had similar results to the previous night, the faintest smell of clutch.

I will continue to update the original post of this thread as well as the body as things develop in order to make this easier for future researchers. Any and all advice is welcomed and appreciated, thanks everyone.
 
I think pulling away from a dead stop very easy is the nature of the beast. Not good to try a fast hole shot, unless you want to wear the clutch out. I'm wondering why you would turn the battery off for such a short period of time. When turning it back on, it does take a while for all the electronics to fire up again.

I understand, but if I hit the gas hard from a stop, the car will barely move from slipping the clutch so badly. That being said, I don't normally cut off the battery when I park, I did it that time right after the trans started acting up, solely to see if it would fix the issue, which it did (thank goodness).

You are correct... I have had to do the same thing. The electronics on this car do get kind of strange. A hard reset does fix things, a lot of the time.

Unconventional solutions to unconventional problems lol. I did it again yesterday before I left work, and the light didn't come back on.
 
The clutch should not absolutely slip in any detectable way . I found that the biggest improvement occurred after the PIS set. I had mine set very aggressively- to the point that i had to watch my foot on the accelerator while taking off- there was no slipping the car just leaped forward. Now it settled and I need to go get it set again- about 1000 miles after replacing the clutch and the initial PIS setting. FYI the PIS setting made by far the most difference in performance- more than installing the FD DBW in my opinion....

Thanks for the input, that is my next step.
 
jlobo941, Best advice is to do the reset and see if the problem returns or not. Sometimes it's just a misshift or temporary glitch. Having a properly set PIS and a well bled hydraulics is always an important step. The DBW is meant to be installed on top of a properly working F1 system, it's not going to fix an issue that is sourced from maintenance issue, a improperly configured PIS or a hardware issue such as a glazed clutch. It will likely still help in these cases but it will not solve any underlying issues. Feel free to give us a call if you need anything

Best Regards,
 
Absolutely make sure that they check the fluid level and bleed the system while they are at it. one would assume they will do that every time before setting the PIS but we all know they don't.
Due diligence is very important here...

Finally got it into the dealer, the technician said the way my car takes off from a standstill is absolutely not normal, and suggested there may be air trapped in the trow out bearing. They are doing a full flush and bleed of the system, hopefully this fixes it. $480 so far. Another note, my clutch was done by an independent dealer, and supposedly towed to the dealer for flush, bleed, and PIS reset, but the technician noted that it doesn't appear the lines have ever been removed.
 
I never liked the idea of one place putting in the clutch and then the dealer wrapping it up...If you fix the cars then you should have the software...What happens after two weeks you get a gearbox fault? Back to the dealer? Who knows how much clutch life was lost because it has been incorrect this long. I'm shocked the dealer will even do it...We do not do anything for other shops.....Helping a competitor is pretty stupid business wise....Burger King doesn't loan McDonalds mustard.....Jason

I agree with this completely. Its just better to have one shop do the whole job that way you can go back when somethings amiss

Update, PIS reset and F1 system flush have remedied nothing, $500 down the drain and still at square one.

Yeah, this was all done before I bought the car, certainly not how I'd have done it.

Jason you are helping the customer not the competition. The customer will appreciate it. The competition doesn't care. We do it all the time for film makers -our customer base....;-):wink2:
 
What ? Did you read my post? I'm not sure how it benefits me to setup the clutch on a F1 car after another shop installed it? Please explain? The customer is not my customer...He would be someone that didn't want to pay me most likely and had it done elsewhere...No thanks, sounds like a good way to get sucked into BS..Trust me as I have done stuff for other shops before and always regret it..That maybe the film industry, but not the car repair business...I guess the thankful customer will now bring me his car? No, but I like the theory...98% of the time it doesn't work out that way..Jason

I see where you're coming from Jason, it's all a matter of personal preference. I live in Denver, and there's only one facility with the software needed to set up a Gransport, and it's a dealership. There are actually 2 Maserati dealerships, one Ferrari dealership, and a handful of independents, and no one else has it. They charge like $600 for the PIS adjustment and flush alone, so I can still see where it's beneficial for them to help out on their bottom line, even if they don't do the whole clutch job. If they didn't, there would be one facility, and one person in that facility who has control of the entire market, and that's scary.

All that being said, do you have any suggestions or insight into the problem at hand, I'd love to pass along some tips before these people spend me into the ground.
 
Sorry, I don't want to jack your thread... I actually have no idea...It is pretty hard without actually seeing what the car is doing and looking at the data...Jason

Yes I understand how this could go south very quickly. Maybe that's your experience. I just like to try to help someone in a bind- a personal preference I suppose...
They do pay back....most of the time:thumbsup:
