I agree but if I was willing to own an AT then I wouldn’t be in the VQ community. I’d be driving an ISF. Only left the Lexus community because they stopped making MT.

Granted there are a lot of faster cars.I'm not going to open the can of snakes about MT and AT.Yes I have stick in other cars I own.

I have followed the Z over the years.Buddy bought a new 240Z when they came out.I liked the look of the 370Z.Bought a roadster.It just did not have the HP I liked.

Now I have a car I think looks great with plenty of Horsepower and fast shifting automatic transmission.Whats wrong with that?

Nothing. You build what you enjoy. I have nothing against ATs. I just prefer MT in my sport cars, even though I know the modern AT is ‘faster’.

I've been looking into this a lot for my 7at, running low boost right now until my "fun" budget is built back up.

IPT (Import Performance Transmissions) in New Jersey builds them a bit better than Lvl10 from what I've been told. The guys in Dubai abusing the **** out of their boosted Nissan Patrols (same transmission) send their transmissions to IPT here in the states. I personally know of a guy with a 7at g37 that was built by level 10 and still busted it. Took it to IPT and it's been running strong ever since.

I'm personally saving for the RJM solution. It's worth the cash, they build it up more than the other two solutions. Overkill if you never plan on going past 600 or 700whp but beyond that, RJM's transmission will outperform the other options.

It is a lot of money.
But thats the disadvantage of ATs is their AT upgrades cost hella lol.

MT clutches and tranny hold a ton of tq!

the modern AT isn't faster when you can run 1100whp through the manual lol

we will see
im lucky, i have fully built GTM 7 AT

blueranger · 06-30-2018, 11:12 AM

My built 7AT has been solid for two years at 650whp with weekly trips to the Dragway. Not sure how much more power it can hold once I go 800+ whp.

Would be great if we can adapt a TH400 with transbrake for us dragstrip junkies.

For those looking for a real bulletproof transmission option. RJM released their Transmission package as well as upgrade path for the 7at. Below is what they have it priced at:

Triple disk Carbon clutch Torque Converter (Upgraded disk, twin spring upgrade, reinforced tabs and etc...) - $1200 retail ($300 core charge)

Billet Flexplate (Fast Intentions) - $1000

Fully Rebuilt Transmission - $4500 ($1200 core charge)

The full build should net you $6700

So far they have tested this trans on several cars from the whipple supercharged cars with instant torque on demand and twin turbo setups. Most cars are running around 550-600ftlbs to the wheels and the temps on the trans is not over 200* when paired with a trans cooler. They just replaced a level 10 setup that failed on a AAM TT customer car and the new transmission is insanely good compared to the failed Level 10! In fact they are running nearly 100whp more than the level 10 that gave out.

Message RJM directly. Fast Intentions also has them in stock.

Would a full rebuild be recommended on a 7AT with 75k on it? Also would the full rebuild have larger /stronger clutches in the higher gears? By the time my build is done we may plan on getting head work done if not filling building the motor to see what the SOHO stage 2 kit is capable of. Seeing as one just hit 615WTQ on 93 in second guessing going cheapish on it and not fully building it from the off. I messaged RJM the other day and they replied but told me they were driving so they would get back to me so I'll hit them up tomorrow lol. Thanks

RJM isn't the only one doing transmission.

IPT https://www.importperformancetrans.com/ also do rebuild. I had Level 10 transmission and I blew it 3 times. Did my research and found IPT and he rebuild my trans. I've been beating on it whole summer since July and one full track day and still holding up well. Level 10 couldn't last a month with me. Even on 2nd week, I was having some flaring between shifting, mainly 2nd to 3rd and 3rd to 4th.

*Just a kind reminder* As a user, I'd highly suggest doing extensive research before going this route (think carefully for the so-called 7AT performance rebuilds of our Zs). PM me if you want to know my story.
