theDreamer · 01-30-2013, 08:58 AM

There seems to be a lot of people wanting to discuss the 7AT and forced induction and now there is a dedicated thread for Q&A, info, build links, etc.

Factory Transmission:
Nissan/Infiniti JATCO JR710E 7 Speed Automatic transmission: Link

Torque Rating:
RE7R01A: 400Nm (295lb)
RE7R01B: 600Nm (442lb)

Quote:

FR 7-speed AT has realized a wider gear ratio range by increasing gear steps, and improved fuel efficiency by reducing friction. Furthermore, it has expanded the slip lock-up area from low driving speed to high accelerator position angle, achieving both high fuel efficiency and running performance.
The latest control technology realizes impressive driving pleasure.

GTM: The GTM transmission upgrade takes advantage of better friction discs from OEM D-0530-31 to GTM D-0880-88 which allows for a better heat capacity resistance (35% over stock). Clutch friction plate surface area by increasing the number of clutches from 32 to 44, increased torque holding capacity by up to 40%, and separator plates specifically made from high-quality steel to ensure durability.

Thanks, will add that to this and the finished builds thread.

m3chhawk · 01-30-2013, 09:22 AM

Just as a heads up 310 kW is 416 HP for us dumb Americans

tower74 · 01-30-2013, 10:26 PM

I know I had you cross mine off the list but it was 481hp and 427tq on an 7AT at 9.5 psi.
Only saying that to show the tranny CAN handle the hp & tq. I know a lot have said I didn't "drive" the car but those around KC know better

.
I put the kit on my car at 2600miles on the car and I'm taking it off right now at 20,800miles.
Before the tranny was tuned (somewhat) I noticed I was slipping between 3rd and 4th. It was actually upreving before shifting into 4th gear. After some tweeking to the shift points I never had a problem again. I also never drove the car hard in the automatic side.

My question to the ones that had their tranny blow up on them..Was it tuned? If so how long did it last after the tune?

Z eliminator · 01-30-2013, 10:56 PM

How did they tune it ? what was different in the tune ?

thanks

Jordo! · 01-31-2013, 05:03 AM

Hmm. Definitely curious to learn more about the apparent failure rate and failure vs power/torque levels.

Rod Saraiva · 01-31-2013, 04:35 PM

Today I'm up the presure to 0.8, and at night I'm going to test it

G37sHKS · 01-31-2013, 05:25 PM

Does G37 with 7AT count as well?

valpozguy · 01-31-2013, 05:37 PM

Subed. I'm f. I. As well with auto. 490whp 400wtq. Uprev tune and uped line pressure. 6000 miles with no problems.

[QUOTE=Z eliminator;2139712]How did they tune it ? what was different in the tune ?

I was sent emails (tunes) until I felt it was better. Noticed a lot of the tunes had really hard shift points but as we went along those issues disappeared. No slipping or the engine revving up before it would shift to the next gear. Uprev can and does do these and your tuner should be able to do this as well.

how hard have you pushed yours with the 7AT that its still holding up good with no transmission mods besides line pressure?

valpozguy · 02-01-2013, 05:52 PM

I hammer on it multiple times every time I drive it. So far so good. Trans cooler is only mod.
