The problem I have is your going through hoops to bandaid a problem. So what if you get one for less than $5k. You still have a transmission that can break... or you can get a fully built trans that can take whatever you throw at it. To me it's a clear decision but that's probably because I have built so many of these cars that I am at a point to spend money where it counts. Going cheap just means double the labor in 90%+ cases... and then buying the right part the after I spent money on the cheap fix...

Also we are in the middle of moving into our new space. Once we are settled we will have a big open house. I would expect it to follow Zdayz. Until then we are heads down on completing orders, moving and designing new products for the VQ and new VR platform.

Party at Bobby's house?

Ok ok, I thought you were talking about the Jatco 7sp trans found in the QX56 and some Nissan Titans. Also uses a RE7R01 trans like the Zs, but have a higher torque rating.

That is the part number & price of the transmission factory installed in the Z,,,model #'s are JR710E/JR711E & yes- they are built by Jatco.
I didn't know there was a discussion about installing the larger version's,used in the SUV's etc...

jchammond · 03-30-2017, 08:32 PM

Heck,,,just put a Lenco in it.

Well that's what I was saying. We don't know if we can use the larger version in our Zs. Probably not.

The newest 5.6L V8 Titan truck puts out 390hp & 394tq @flywheel...just say's 7sp.A/T
unsure of model # or power handling of it.

The one with the Cummins 5.0L & 555tq. comes with an Allison 6sp.auto & not a 7sp Jatco...Looking like 400'ish TQ is about the limit on stock 7A/T's...& being able to have one built to withstand 800+TQ 1000HP is pretty good,considering 1st gear is nearly 5:1

shadow85 · 03-31-2017, 06:37 AM

400 ftlb ~= 540 Nm of torque. This is pretty good for a stock trans that wasn't designed for forced induction yeah?

Except the 370z does not have 400ftlb from factory.
Forced Induction & 7AT 370z Info

The 370z has the RE7R01A, the B is the higher rated transmission in other Nissan/Infiniti cars which has been discussed if possible to just put in a 370z but never done. Probably because in is just cheaper to build the factory transmission at that point.
Torque Rating:
RE7R01A: 400Nm (295lb)
RE7R01B: 600Nm (442lb)
