VR transmission swap

I watched a video by Infiniti Brothers where they swapped a VR (Q50/Q60) transmission into a G37. Has anyone done this for the their car yet or know how feasible

Default VR transmission swap

I watched a video by Infiniti Brothers where they swapped a VR (Q50/Q60) transmission into a G37. Has anyone done this for the their car yet or know how feasible this is? Can't afford the built tranny quite yet, but word has it the newer trans can support up to 500wtq.

Looking to start a discussion about it and maybe a DIY thread in the future.

Yes guy on Facebook, it’s a straight forward install and pretty much bolts right up. Something with making a crank trigger switch hole bigger. I’ll try to find the link

So, it looks like what's needed is:

-Need to swap TCM from the 3.7 7at to the 3.0TT 7at
-Need to make a new hole for the crankshaft sensor on the transmission bell housing
-Need shorten driveshaft 1/2" (might not have to do on the Z because it's shorter than the G?)
-Need to fab a custom transmission bracket

What would a shop charge for labor? $1,000-1,500 or so?

I wonder if this would be worth it for N/A guys? The transmission does seem to shift faster from videos in the facebook groups

Being the G(Z) TCM is used and that's what dictates shift speed, are you sure the Q transmission (hardware) is doing the faster shifting or is there a tune involved feeding higher load commands to the TCM and making the Q trans shift faster?

My 7AT shifts pretty dang fast with the TCM getting higher load % via the ECUTek tune.

What's the FB profile name?

Look up Adel Taw in the "VQ35HR / VQ37VHR Discussion" group on FB. He's the 1st one I believe that did this swap on a G and has a few videos. His G is supercharged so there most likely is a tune involved making it shift faster.

Also, so far I haven't seen anyone attempt this swap on a 370z.

I think he did the video linked in my original post.

He swapped the solenoids from the G transmission to the Q transmission as well, i believe.

I agree that the shifting may also be adjusted with a tune, but I've also heard that the Q's transmission will hold more power.

Thanks guys maybe a viable option when OE Z/G transmissions let loose.

He did reuse the G solenoids as he said it would not shift with the Q's installed. Probably a disagreement with the G's TSM. I don't see why it wouldn't go in a Z as well as the 7AT's are the same between the G/Z.

This could be huge for the guys who realize their stock 7AT isn't up to the task once they catch the FI bug.

Just swap the bell housings. The trans itself is still a RE7R01A-there are differences in gear ratio’s-see attached. Only reason that you would have to swap valve body’s that have the TCM integrated would be due the logic for ECM mapping or for some reason the VR 7speed TCM software has some discord with the 3.7 ECM-though that shouldn’t be the case since the 3.7 has the same internals as a VR 7 speed. Looking at the wiring diagrams for both-only difference is the 3.7 uses pin 4 for ‘k’ line to the DLC. See attached pics. Also side note... a long time ago when the 3.0 first came out I wanted to see if a 6speed mated up with a clutch installed, and it sure did just crank position sensor holes were off.

Can’t just swap bellhousing, the transmission code is the same but got different internals, the reason you can’t just swap the bellhousing is because the vr30 torque converter is bigger than Vhr and it won’t fit in the VHR transmission housing, now you thinking maybe try the vhr torque converter and bellhousing and I say no it won’t work since the output shaft is longer and vhr torque converter won’t work.

So this is probably something I’ll never do because I’m not boosted but it is an interesting swap. I’m curious though for the people that are killing the stock trans is it the torque converter that fails or the internal clutches? I ask because rebuilding automatic trans can be fairly easy and straight forward (although I have no first hand experience on this particular trans) so does anyone just sell a higher count clutch pack for the stock trans? Typically in other trans (again no first hand on this one and it’s been a long while since I’ve done an auto) there is room to fit more friction disc, often they’ll add more plates and those just get used as spacers so you can remove some of the plates and add more friction disc. At least at one time this is how automakers would use the same trans with different HP ratings etc. if this is the same trans with different bell housing and torque converter then I wouldn’t be surprised if it’s using the same carriers with just a different friction disc to plate ratio.

I’d think this would still be an easier route than having to have a driveshaft made and doing all the missing but maybe that’s me.
