That is actually the same trans in the G37/370z... The RE7R01A/JR710E is rated for 295lbs. You are thinking of the RE7R01B.

No, I am talking about the same model tranny but it is changed. They tweak each model tranny from year to year. The Q50s is rated different across the board. Look at the FSMs. If you reference each FSM you can see the slight changes made to the different tranny sub-models throughout the years. Not all RE7R01As are made the same it would seem.

Hmm interesting. I just assumed it was the same with beefier clutch packs. Time to do some research.

So is that just for the Q50 or is that also for the 370Z 7AT? I.e. could the later models have a stronger tranny?

Yes, there are different variants of the Nissan 7 speed transmissions all with different build specs and control software. Torque management, engine variables (programming) and even torque convertors will help prevent damage and help maintain transmission life.

The magic number for our cars is still below 400 ft-lbs of torque and its the 4-7 gears clutch packs that are in danger of being slipped around that torque range. It's amazing how just little material is in those clutch packs.

There is no magic solution to this problem. If you want to boost a automatic car and have more power and torque than stock, you need better clutch packs, torque convertor and heat management. OR eventually you will burn out the transmission .... period. Just like a manual clutch will eventually fail from more power than stock.

Consider a upgrade to the automatic transmission clutch packs, cooling etc for a car you want to boost and make more power. Or don't boost because you will wind up paying way more in the end.

The parts you need are out there and any competent shop that's local can do the work for you. If you want the best and can afford it, Level 10 is the shop to use.

There are NO shortcuts

So you think the clutch packs (in addition to a trans cooler) are the most important upgrade over the trq converter or flex plate for a car running high 300s/400ish trq?

I would do all of the above .... only as strong as the weakest link

I agree, outliers notwithstanding, flex plate, torque converter, valve body, clutch plates, transmission cooler. It's my understanding (and maybe it's just favorable marketing) that the upgraded clutch plates take someone with experience to install them due to the extra thickness of the plates? Which is why lots of guys have their transmissions shipped directly to Level 10. The valve body is matched to the TCU so you need to use the one on your car, again necessitating shipping it out.

It's kind of why I was interested in the "B" revision transmission. At least it's rated at 400lb ft. out of the box. Figuring out which cars/SUV's it came on has not been easy though.

:wtf2:
any mod feel like pruning this thread and moving the 20 pages to the 7AT & power sticky? There's alot of decent info in the discussion about the 7AT in here which will probably be hard to find to anyone searching

No one in here with a 6 speed is spending 20 pages to figure out if they will need to change the stock clutch to go FI

Get your tuner to ramp the timing down before the shift point like the OEM's do and hope for the best or cough up for the upgrades required from Level 10 or whomever

Yea no kidding, let's get back to why we were brought into this thread. This kit being produced! Any new updates fellas?

brucelidat 07-11-2017 02:10 PM

They said it's coming pretty soon, exciting stuff. It's really great that an older platform like the 370 is still getting some great new after market products and support.

If we pruned the posts about ATs and the posts about possible hood designs, this thread would only be like 2 pages.

brucelidat 07-11-2017 03:39 PM

hood designs are relevant because they are necessary and specific to this kit

Ape Factory 07-11-2017 03:57 PM

So is the 7AT and those who own a car equipped with one who are considering this kit.
