I purchased a used automatic 2007 g35x about 3 months ago and have noticed that when using the car first thing in the morning it doesn't seem to shift easily from park.

I am only noticing it now, and a good mechanic gave it the all clear before I got it.

I used to have a Toyota Avalon with a very smooth shifter, is this just one of those quirks with these cars?

 

It's normal, took me a while getting used to it after coming to the G from my Acura. After the car fully warms up and the warm fluid gets through the tranny, it's shifts super smooth. No worries!

 

If you don't let the car warm up in the morning, the shifts will be a bit stiff until it gets to its optimal operating temperature. And is bad for the engine to just start it up and drive off in the morning.

 

I do let it run for about a minute, though I admit its not at operating temperature. Should I let it run until it reaches that point?

I have heard that since the fuel injector adds additional fuel to the fuel / air mixture to help warm up the car faster it causes more carbon buildup in the engine and leads to more contaminates in the oil. By starting and driving sooner, your engine is up to operating temperature much faster and this rich fuel air mixture cycle is much shorter.

 

When I had an 07x I would do this...

- start car and wait 15-30 seconds. The rpm's never went below 2000 yet.
- press and hold the shift release button
- pull the shifter slowly, about 1/2" toward drive, pause for a second or two and you should notice the rpm's drop quickly
- continue to pull the shifter into R or D.

It always worked for me at getting the rpm's down without having to wait more than 30sec for a warm-up. There is something in the programming that tells the car to drop the cold idle when you are shifting into R or D. You just have to give it a couple seconds to realize it and it will drop the idle before you put in gear.

 

I can't say I know all of the ins and outs of letting the engine warm up. But for my cars I always let them warm up for a few minutes until I see my temp gauge go up to about where it would sit during operation. Only times I experienced a rough shift is if I ever had a hair up my butt and turned the car on and bolted after 15 seconds or so. I never heard about the carbon build up though, so maybe someone can commentate more on that.

 

Cold transmission - perfectly normal. Also, take it easy when you start to drive - it takes a while for AT fluid to warm up.

 

Don't even need to shift it to make it go down. Simply putting your foot on the brake pedal will cause the rpms to lower. It's like you're telling the computer that you wanna drive NOW lol.

 

That was never the case for me in 4 years.
If simply pressing the brake pedal dropped the idle to <1000rpm then there should be no one with this 'hard shifting' issue.

 

Hmmm that is weird for some of you guys, never once has my car had an idle of over 1k, every time I start my car it sits at 800.

 

You may want to get it checked out if that's the case.
Even if you live in a warm climate it should be ~1500-2000rpm for a few seconds before dropping to ~800rpm.
I live where it gets cold and ~2000rpm is a common occurrence, even parked in my garage all the time.

 

SAme goes with my G once i press the brake pedal the idle start to lower down a bit quicker kind off weird, at first i thougt my g was just beeing stupid but i guess not, since im not the only one noticing lol

 

The fluid works too good when it is cold. Once warmed up the fluid is not as dense so it shifts easier. I just hold the brake pedal down as well after waiting 30 seconds. That drops it to about 1400/1200 and I will usually put it in drive or reverse after that. It still clunks unless I fully let it warm up (a few minutes). Sometimes my fiance will have to move my car in the morning to get hers out. I was in the shower one time and heard my car CLUNK into reverse. I had to go over the whole warm-up-brake-pedal thing with her.

 

I usually allow my G to drop to at least 1000 before taking it out of park. I feel like its necessary to allow for the fluids to warm up before you start to engage the engine.

 

^ Off Course, goes like that with any vehicle, idk about hybrids but pretty sure has to get warm up ? anyone knw the answer for hybrids lol.
