A few tips about G-35 Coupe or Sedan 6 MT

[Jacko3]

After over a year of driving my car, these are my observations about the transmission of my car, and possibly other Gs with manual transmission.

1. The 3rd gear, while it has some serious torque, it is the most inefficient gear under WOT because it consumes more gas than any other gear for the power it produces. If you can, avoid its use under WOT if you want to save gas---quickly go from 2 to 3 (quickly) and then to 4. I actually see my gas gauge move under WOT in 3rd gear. And what is even more annoying about the 3rd gear is that it tops out at 90 miles per hour. If there is ever a reason to replace any gear in the transmission, the 3rd gear, in my opinion would be the first to go.

2. My fifth gear has impressive torque only above 1** miles per hour. 4th gear is the best in torque but it starts stressing when it reaches 1** miles per hour, but still works well at over 1** miles per hour.

3. When stopped at a traffic light, avoid depressing the clutch---let it out and leave the gear in neutral. I know this is hard to do and asking too much of anyone as even i want to take off immediately when the traffic light turns green. But what i have found out is that since our engines are high compression engines 10.3: 1 ( I am not very sure about this ratio), it produces a little more heat than a regular low compression engine. What this does is that when you stop at a traffic light, while depressing your clutch in anticipation of taking off, the heat generated from the engine may tend to slowly dry out the grease in your throw out bearing, eventually leading to a tougher clutch pedal to depress, in time.

These are just my observations and 2 cents so far. Of course, these assertions are based me driving a 2007 G-35 Coupe 6MT with some modifications such as a pop charger, spacer, mrevv2, and Stillen Cat back exhaust. I assumed the sedans would be the same with modifications, however, their lighter weight may make this phenomenon less obvious than in the coupes.

Very good Jacko...

But the 3rd gear thing... well that is in my book..

I love 3rd gear. It is accually my favorite gear

No but really it is, You have so much power in 3rd... well maybe it is just in the sedans that you feel all that power!

I agree with you, the 3rd gear has a lot of torque. Actually, I need to qualify my coments a little, my assertions are based on having some modifications such as an air take , plenum spacer and mrevv2.

The reason why i made my comment about the third gear is based on the amount of gas I use under WOT compared to the other gears. These assertions maybe different for the Sedan 6MT.

Weird that you don't like 3rd...I feel that's a great passing gear when I want to pass quickly at 55-60.

Jacko... I hope you understand my Humor about the coupe/sedans...

I even use it to pass 70+ lol

Joe603:

I like the third as any other gear. The only reason I have issues with the 3rd gear is that for the power it produces, it uses up more gas than the other gears. I just see it as a gear that has an inefficient power to gas ratio.

If gas prices were low, I wouldn't even bother at all.

The 3rd gear even gets worse with its inefficiency as you approach the 90 miles per hour range. So, I tend to shift into 4 from 3, at 75 miles per hour, since my second gear alone can reach 60 miles per hour---redline. All other gears are great with gas under WOT.
