Please, please do this. Ideally, something like a GoPro mounted to the steering column showing rpm and gear (if in manual).

I noticed that Stillen doesn't have anything like this, and they only suggest getting the transmission cooler kit. I would definitely like to see the difference between stock and what you have.

The valve body upgrade would be a great mod if it wasn't $500 overpriced.

Nice find. If you add up all those parts + shipping, its going to be 40 dollars for a 10 dollar part.

You dont need the ball valve, as you fill the trans through the overflow port.
Fill, remove the fitting, allow the overflow to drain, replace the plug.

Btw...if someone does the 7AT flush themselves, can you please post a DIY with the procedure and what oiled is used? I'm definitely interested in doing the flush.

Some say that the Uprev tune will change the shifts for the better. Some have installed the Transgo on their own. I'm sure GTM uses the Transgo as part of their upgrade but $880 with less than a days worth of turnaround is insane. If they had a price in the $500 range this would be one of the most popular performance mods for the autos.

I agree, because I understood that the 7at had to be done by the dealership because of the machinery that is used to do the flush and fill

That and ATF temp. When you do it at Infiniti, they have to wait until the temp of the fluid is between 98-104 degrees to do it accurately with their equipment.

Me thinks the GTM one day turnaround is a core exchange.

The Uprev modification increases line pressures by increasing expected power
parameters. It does affect downshift response, by needing more throttle input.

Im going to revert mine back to stock.

Actually, FSM states around 40c. Not more, not less. The fluid level is very sensitive to temperature change. So you dont want too much less than 40c either.
