I bought 4 gallons of ATF, had a couple quarts left over.
Rear jack point is the bottom of the rear differential, and the two rear side rails for the jackstand placement (the same place you locate the OEM scissor jack). You can also put jackstands under your rear spring buckets too.
I used a bucket w/ gallon & quart stripes, not this one but this would work too, it's on walmart.com

Awesome thank you! Do you think you can provide a picture of the jack placement just so I'm 100% sure. Thanks again!
Here's a pic of where to put them, on the pinch weld area where you see the indents in the weld (they are a couple inches apart and you put the jack in-between those indents). These stands have a rubber adapter, you can also use those rubber inserts in a harbor freight jack and have the jack set like the last pic.
Here's that insert

I just use a couple shop rags on top of those harbor freight rubber sleeves and it's worked out well, the rubber is still in good shape and no abrasions on the rocker panels.

Sorry for asking so many questions! Would you recommend dropping the pan and cleaning it out? I'm at 77k miles and don't think the car has ever had a drain and fill done to it. If so what did you use to clean out the pan?

Just bought 4 gallons of Maxlife ATF and getting ready to do the drain and fill. Anyone have a link to 2010 g37x coupe torque specs? Also did change the washer for the drain and fill plug? I change the washer when i change the oil and was wondering if its the same washer as the engine drain.
Was wondering what the transmission pan torque specs and drain and fill are. Thanks in advance!

From FSM under TM (Transaxle & Transmission) page 274.
Overflow plug = 12.4 nm or 9 ft/lb
Drain plug = 34 nm or 25 ft/lb
Mounting bolt (24 total) = 7.9 nm or 6 ft/lb
The AT drain washer is the same as engine oil plug but not the AT overflow plug (M8)
4 gallons ATF should be enough for 3x fill and drain plus transfer case.

I've also read on another forum that they swapped out and replaced the transmission pan bolts. But is that really necessary?

I reuse all the washer and bolts on my G37x without any issues, my only concern is the gasket but so far so good after putting everything together the car drive little smoother but not much notice any difference.
Dropped the pan. Do I clean the inside of tranny too?
