Not a whole lot of built 7AT running around and for reason. The 6MT is a stronger unit if boost is in the plans.

To answer your question though, a cooler certainly doesn't hurt and maintenance is going to be a big player. I imagine you should do new fluid every 30k miles so it stays fresh for the clutches. There was a member who went through level 10 for a full build on his 7AT and ultimately parted out his car after three or so rebuilds of said built 7AT.

1-4 appear to hold boost better than 5-7 (from what I gathered on the Z forum). So, if you stay out of boost in those gears it should prolong the life of the 7AT if it isn't built. Ultimately, I think a VR30 7AT is the route to go if you want to boost your auto car. Takes a bit of modification and know how but those units are built to take the additional torque vs. what's in the G37.

Interesting, I never knew! So, the "JATCO RE7R01A TRANSMISSION" is found ONLY in the Red Sport? If so, that makes the Red Sport a little more interesting (cuz otherwise it's not that exciting vs the competition).

I am new to Nissan/Infiniti, had my G37x since Oct/Nov last year with 119k miles.... I thought the 7AT sucking/hesitating/slipping was due to age, mileage, condition or just needed a fluid change and maybe a valve body upgrade. After further research and reading, it seems the 7AT just sucks big **** from the factory

I too am considering how hard it'd be to swap the 6MT and ditch this 7AT... . It can't be any harder than swapping the VR transmission. Could probably save a little weight and while it's out could add some upgrades to make it bulletproof i.e. upgraded clutch, flywheel, etc.

His prices are very reasonable imo. $260 shipped is not bad at all

What are you tired about?
Unlikely that you should be outpowering your transmission.
Built trans usually come with a better TQ, possible upgraded Valve body and maybe some clutches but shift logic will continue to be the crappy one.
I recently had an interaction with John owner of IPT and they stand by their products.
The goal for asking in forums is to get the best advice for you.
Maybe what you'll need will be VR transmission, more tinkering in getting it to fit however great results have been shown

Again, without knowing your complaints, driving styles, goals and budget we cant help much.

After my albeit brief research about our 7ATs... reading forums, checking prices on parts, checking out vendors i.e. Level 10, IPT etc... thinking that short of a full rebuild of the 7AT, the best I can do to "help" it not suck so bad at shifting or lurching/hesitation etc is to get the ECU tuned, change tranny fluid, maybe upgraded valve body. But that's about it. Outside of a full rebuild complete with a better torque converter etc, I don't think there is much help for us auto guys.

I wonder why more auto guys don't just swap to a 6MT? I haven't looked into it, but I can't imagine it's any harder than swapping the VR (Q40/50/60?) transmission into our cars... and people have done that so.....

I just can't understand nor justify the prices of a fully rebuilt or even slightly modified 7AT + upgraded tq converter etc unless you were "going all out" for some special build or just had the money to burn. I think last I checked (going off of memory in my head so don't quote me), it was something headed towards $10,000 once you build a "bulletproof" 7AT + the valve body + torque converter + install yatty ya blah blah.... whereas what's got me curious about swapping to a 6MT if/when I need it is this: OEM 370Z/G37 Manual Transmission that Z1 sells for $2116.89. And that's BRAND NEW! Even adding all the extras and goodies i.e. upgraded clutch/flywheel, CSC elim kit etc, you're still UNDER $4000 total....

Please someone step in and tell me how crazy I am or what I don't understand or why more people don't just swap to the 6MT? Imagine finding one used, then rebuilding/upgrading that thing to the max... still gonna cost you less than a fully built Level 10 or likewise transmission. So do people stick with the 7AT cuz they don't know how to drive a manual? Because they have a wife and kids and "it's just easier to drive an automatic"? Or is it because a fully built "bulletproof" 7AT is better than a fully built/bulletproof 6MT?

I think you should visit this thread:

https://www.myg37.com/forums/build-t...l-worklog.html

That's the culmination of going all out on a 7AT. TL;DR - even a fully built 7AT isn't going to cut it. Owner eventually parted out to move onto a platform that could handle what he's looking to do.

For a platform, tuner one at that, that's been around for over a decade, if the 6MT swap was that easy, you'd see more of them....even one - there's a reason you don't; it's much more involved than you think. You'd need, at minimum, engine harness, manual trans & clutch, all of the interior parts (clutch pedal, gear shifter and the panel for the shifter), ECU, and a new gauge cluster that’s for a MT. Then, you'd need the TCM to the ECU to the BCM to play nicely together. It's going to be significantly more expensive than 4k; especially if you need to rely on a shop.

If boost is in your plans, and you don't want to drop the necessary cash to build the 7AT or go through the trouble of swapping in the VR 7AT, sell your car and grab the best condition 6MT you can find.

Just to add - a G37x with CAIs, HFC, exhaust with a tune is a potent combo. Add in good (not the damn eBay specials everyone flocks to...) coilovers, sway bar, wider & lighter rims with good rubber is a lot of car while being super reliable with proper maintenance.
