Re: Love the car, but what's with the gear ratios? [r34fan] by jagguar

Oh, and also, I don't know why you would buy a 6MT if you're complaining about the low gear ratios. That's the whole point of getting a manual with 6 gears. It gives you much more control of your power. I'm also really happy about the fact that 6th gear has as high a gear ratio as it does. I can hit 100 mph before I get to 4000 rpms. If the driving is a little rough for you, just take it easier on the gas pedal. I've been taking it so easy on my car and I still end up with the rest of traffic in my rearview mirror.

Yes, I have tried it many times. I do not know why you do this, but I do it because it has a rough shift between 1st and second (not from any other gears, up or down).
Do you have the same problem or you just tired of the very low gears ratio?!

Rough shift from first to second. by lwechsler

2006 G35 Sedan w/6600 miles only.
Had rough shift from first to second from day one.
Dealer said (1000 miles) "Thats OK".
I dont think so but there is no way to contact the factory.
The general dealers complaint office in the South East recommends you back to the dealer.
To avoid ruining the transmission I have installed a mechanical reducer for the accelerator, for softer start-ups with this 300 HP monster. It helps a little.
Anyone out there with same problem?!

I already left a messege regarding hard shifts to day, however I will go in to more details here.
Because the shift from first to second is rough 9 out of 10 times, I have designed, built and installed a mechanical accellerator reducer.
This (relatively simple device) attaches without any drillings to the car. it reduces the ratio to 3 to one for the first 25% of the accellerator's pedal range.
This allows for softer shifts and reduces wear and tear to many parts of the drive train. after you pass the 25% it works normally. I did this because no one at Infinity is able(or willing) to contact the manufacturer in order to change the Computer Program Software for the accellerator, which should be very simple to do.
My device (second generation by now) is anchored to the seat bolt that connects the seat to the car, so it does not affect anything on the car except the ratio one depresses the accellerator. This affords much softer starts, yet retains full power, if you realy need it.(When driving to the supermarket and back)

After reading the suggestions in the above email from [nefariousbc)I went to test his theory.
Indeed if one presses on the clutch half way down when shifting from first to second, it improves the shift by about 50%.
With that in mind one does need to depress the clutch all the way when downshifting to second or first.
Very good advice, Thanks

Anyone else have a G35 Sport sedan clutch jam ? by dayamit

I bought a G35S in a manual transmission back in early May. About 2 months into the purchase, the clutch began to feel a bit weird on a long drive to Palm Springs. The shifts from 4-5-6 gears became erratic due to the pedal being "sticky" (not releasing fully) and the "spot" in the release where the gear engages feeling as if is was changing. Example: I would press the clutch and change from 5th to 6th and then try and release the pedal but the gear would engage almost as soon as I shift the knob into 6th position and when I release the pedal, the pedal will not come all the way back to the starting position but be stuck a bit off the floor and I would have to snake my left foot in there and give it a nudge for it to pop back into the original position.
 
This originally happened around 2000 miles and just intermittently for that week. Then it disappeared. When I took it in for the first maintenance, I told them about it but they said unless it could be duplicated, they wouldn't look into it. The last few days, I'm up to about 5800 miles) the problem has been occurring more frequently. Then last night it got bad and all the gears were affected. It was as if the entire clutch was going haywire and I was out entertaining a out of town friend and so I was out driving him around town. Well, I was able to get around but when I was returning home, I got on the freeway and could not shift into 3rd. The clutch pedal was stuck and even when I was able to pop it out with my foot, it locked me out of shifting. Essentially, the gear spot didn't exist anymore. I pulled the car over and coasted to a stop by the side of the road where I was stranded at 3am. I tried to see if restarting the car would help. No dice. Without any other option, I called roadside assistance and they picked up the car. I'm not sure how far I want to take this issue with the dealership and would like to know if anyone else has had this problem or felt something wrong like what I have described regarding the clutch. Please post and let me know. Thanks.

I follow the G35 Tech forums and check for updates daily.
I have not seen even one instance of this in the past, but I'll keep my eyes open.
 
Sounds horrible but I guess there is a bright side.
The dealer said that they could not fix it if it was not duplicatable.
 
Sounds like you duplicated it!
 
Sorry... good luck.
