transmission problem
Hi does anyone know the difference with the 2012 g37 vs the 09 g37 transmission. I have a 09 and the gear delays when I use the paddle shift and the gear also takes longer to change out when am not in sport mood while the 2012 g37 change out faster and has more Power To me. I read up on both car specs and they have the same. I was thinking about getting a transmission flush at the dealer . Does anyone have any suggestions please?
transmission
I have an 09 S coupe 7AT.
It has 50k miles, my local dealer did a $100.00 drain and fill at 45k miles, just to stay ahead.
Drain and fill plugs are both on the bottom of the pan.

the delay from paddle shifters is normal with the car. after i got my car tuned the shifts have been noticeably crisper and quicker. some have also said a simple grounding kit removes the delay from shifting

Do the grounding wire in your engine bay. It improved my shift times.

Spreading the grounding points by using the wires does not help with performance. This has been around since I got my first g35
6mt in 2003. But hey you're probably the type that has a turbinator in your intake as well.

I asked you for proof to back your claim since you sound like you know what you're talking about so concretely. You then retort with zero facts and feel like getting a personal jab in there at me. Thanks for your insightful post. I mean I guess it's my fault for asking someone with **** in their name.
Your mind is obviously made up but I do suggest you read through the grouding wire DIY to better inform yourself. Here is an independent analysis of the grounding wires by a fellow member.
challenge accepted!
just installed mine, took some videos before and some after, and im about to analyze them and ill post them up so everyone can see. as for first impressions, it seemed like the lag was a little bit less in manual DS mode, but the videos will show us the truth lol
Edit:
ok so i opened the videos in movie maker so i could get time comparisons.
keep in mind that these times are at .25x speed so it all really happened about 4x faster, and the time codes dont match up because they are from different parts of different videos obviously... but here's the numbers i got for 4th gear going on 5th (the other gears were a bit harder to do because of shortness)
the click is the sound of the shifter shifting.
4th gear b4 wires-
53.57 click @ 3200RPM
54.62 changes number to 5
57.53 shifts (RPMs drop) @ 3300
57.52 - 53.57 = 3.95 (or about 1 full second real time)
4th gear after wires-
11.61 click @ 3050 rpm
11.66 changes number to 5
13.72 shifts (RPMs drop) @ 3150
13.72 - 11.61 = 2.11 (about 1/2 of a second real time)
the initial time is DOUBLE the time with wires... even with driving variances and the slight difference in shift RPM that is a HUGE diferance. it would seem to me that this did in fact reduce shift time.
but heres the videos i took. if someone wants to try to check the times themselves and maybe find more comparable shifts than it would be nice if you post your results:

on a 6MT where shifting isn't controlled electronically...
As someone who thought they were worthless until I actually tried it. I can confirm that they do work. They even make the Bose stereo sound clearer.
Oh and no I don't have a turbinator in my intake... You shouldn't be so quick to insult people without doing some research first....
You're absolutely right, grounding kits do absolutely, positively nothing and are a waste of time!

Thank you Tachyon for an independent view of how the wires did positively effect your shift times in an automatic. I would even go as far as suggesting the kit for a 6MT because like you said, you can get better audio, so at least there's that. You are absolutely correct that they will do nothing when it comes to shifting a manual
In the case of the OP, I stand by my recommendation, it cost me under $20 to build the kit and also have better shifting times because of it.

To OP I have an 08 5at and when I first got my car with 35k on it the manual shifting was so laggy I would never use it. I did a throttle body cleaning, grounding kit, Transmission flush (not just drain and refill) and an ECU reset. Now the throttle response has improved a lot and it shifts twice as fast as before.
I actually enjoy driving with the paddles now.

Next I will be upgrading the valve body and getting a tranny cooler.
