Haha, well, I do consider myself a cheapass. But I see your point. My previous commuter was a 06 scion TC and that car was hella cheap to mantain and was running strong at 129k with only oil changes. But i guess switching to an infinity does require a shift in how much I need to spend to maintain it.

 

From the photo that car does not have 4WAS.

 

The VIN lookup in the FSM is to check to see whether you need to use 3 quarts 4 oz or just 3 quarts. It is not to determine if you have 4WAS. Since you don't have 4WAS, you will look up the ranges of your VIN for "VIN (without 4WAS)" NOT "VIN (with 4WAS)". You will only need 3 quarts for your transmission.

 

How often do we need to change the MT oil??

 

Should be in your FSM but IIRC it's every 30k miles

 

Thanks I will look into it. I bought my 2008 G37S recently. How can I check the MT oil level?

 

Thanks a lot! I am planning to do my 60K service very soon and this is one of the DIYs I am looking for.

 

Awsome write up ! Did my rear diff today and gonna do the tranny and front diff tomorrow , looks easy enough , thanks for the wrote up its a big help

 

I'm having a little bit of difficulty when shifting from 1st to 2nd gear and I suspect it may be due to the fluid level. When we're filling tranny fluid, should we be filling and checking the level when the fluid is hot or cold? I used Redline MT-85. I want to check it before I see my dealer.

 

I've never heard of checking mt or rear end fluid when warm. The spec is usually to fill until it overflows while the car is level.

The 7at does call for trans oil to be at a certain temp.

Is the 1-2 difficulty under certain conditions or all the time? Maybe change your throttle technique. Ease off the throttle more before disengaging clutch/shifting.

 

It only happens when it's cold. Once the car warms up, then it's fine or if I'm parked and rowing through the gears. I did a BMW AT fluid change last fall and the car has to be running and at a certain temp when you are filling it. When I changed the G37 fluid, it was done cold and filled it until it was leaking out of the drain hole. I wasn't sure if there was a difference between AT and MT. I don't think it's my shifting or throttle technique.

 

^^I have experienced the exact same thing with my '12. Keep in mind, AT fluid is drastically different than MT fluid. AT fluid is a type of hydraulic fluid, where as MT is basically gear lube. At cold temps, it flows like very thick honey (75w90 iirc is the weight). With that in mind, I will double clutch the first few shifts of the day until the car warms up some. This way it goes right into gear without having to force it in.

I had this same issue in the camaro when the car was cold, even when running synthetic gear lube in the MT case. Double clutching ensures everything is spinning at the right rpm before shifting to the next gear.

 

I will do that when I start noticing it. It's been getting warmer here in the Midwest but I'll try to keep that in mind when it starts getting colder again. Thanks sir!

 

Anyone with feedback on the amsoil 75w90 gl4 trans fluid in cold climates (<40F)?

The stock fluid sucks in the cold, requiring double clutching for smooth shifts until it's warmed up.

Jeremy, I know tx doesn't get too cold, but any comments on how the fluid is performing after some time/miles?

 

I had amsoil during the winter here in NY. Dumped it and went back to OEM which is much smoother. The amsoil oil took much longer to warm up.
