I have a 2010 g37x Sedan Automatic i had mostly Manual cars in my life was wondering if this is normal. When i step on the gas hard for example to switch lanes there seems to be a slow reaction from the engine and the gas peddle. Like when i step hard on the gas to speed up to switch lanes the car has a slow reaction to react and speed. Cant really explain it if that makes sense has anyone experience this on there G automatic or is it just me?

lol your mind wants Manuel reaction but I'm sorry to tell you the 7 speed tranny is very laggy, I ABSOLUTELY never drive in D mode for the same exact reason, I'm coming from an automatic altima se-r n the throttle response is f-ing amazing n shift so fast compared to the g which is y I drive either in sport mode or triptonic but its normal.

Agreed - transmission lag is terrible in drive and still an issue in sport. Most concerning is when I press the gas there's a delay, then it drops a few hundred RPM, then goes. There's a thread here about installing a grounding kit adding a larger ground to the engine, throttle body, chassis, etc. where some are indicating improved transmission response and others are indicating its a placebo effect - I have no opinion but you'll find the thread if searched.

Side note - I had an Altima SE-R when first released - 2005 - and loved the exhaust note! Car was a blast to drive, looked mean tinted as it was black (no chrome) with 5% limo, although the rattles and creaks drove me nuts.

yes i rear all the lag forums and and no really ideas on how to fix it thanks for the advice for the grounding i thought maybe trying to tune it or change bigger throttle body would help?

I have another car newer automatic nissan murano and because its new its so much more responsive even though its automatic but i guess because its new.

It would take a comprehensive software re-write by Infiniti. The transmission was programmed for EPA mileage numbers on the dealer sticker. Get to the highest gear as possible as soon as possible and hang onto it for as long as possible. The 3.7 is a bit of a gas hog in urban and suburban environments as it's hauling over two tons around. To date, no one has wanted to tackle cracking the TCU code base.

You have two complementary options -- get a tune which can raise the trans line pressure and/or drive in Sport mode and do your own shifting. I do the second.

thanks for your advice but mine doesnt have paddle, i guess i will just live with it , so guess there is no other way to make the car more responsive

Easiest solution is to drive in manual mode all day but if you have an aftermarket exhaust expect to burn gas, I love my ark n I'm always in the 3-4k rang but in normal drive mode the car usual shifts around 2k.

Yes paddles are great and included in the s model but not necessary. Switch tran into ds and push up on shifter to engage, 1 will be displayed on dash and then 234 etc.. I drive like this 99% of the time.

actually most g37 models after 2009 have the paddle shifter harness under the steering wheel colum trim, my 2013 X sedan didnt come with the paddles but I got them from craigslist n simply swap out to the correct trim n that was it plug n play.

It's been around for awhile and has, and is, used by members. Search for "throttle hijack".
