I have not seen a broken one yet, but I would not hesitate the weld it and rebalance the assembly.

that's great, yeah its about 700-750hp the brazing goes, had 2 or 3 old customers that had it happen at the strip. there used to be a gear shop in Australia that sold a laser welded replacement but it was almost $700 for the one gear/shaft.

I've been getting grinding in 2nd gear and crunchy shifting in 3rd. Do you think a rebuild is a good option for me? This is my DD.

I changed my trans oil and differential oil this weekend to MT-85, still grinding, requires double clutch to shift smoothly.

So I read this whole thread but can't find where I can get a hold of these upgraded synchros? I've had my car for 4 years (been boosted for the last 3 years) and it's always scratched if I shift into 5th or 6th too quickly. I've just been living with it but I'd love to find a solution!

Question. Is our manual tranny the same as in the 350Z?

JARblue · 10-24-2017, 02:13 PM

Doesn't look like it.
The 350Z MT part numbers start with 32010*****
The 370Z MT part numbers start with 320B0*****

Hey man. The Transmission has been doing GREAT. Been in just over a year now and number track days on it. Still feels very smooth in and out of gear.

I cannot thank you enough for the rebuild. It's been nice not having to worry about it now.

From what I can tell they are the same inside. Both have the same gear ratios.

Gear ratio
1st 3.794
2nd 2.324
3rd 1.624
4th 1.271
5th 1.000
6th 0.794

Chrisc3 · 08-03-2019, 07:48 PM

I lost 5th and 6th. I need a rebuild. Any updates

scope22 · 08-03-2019, 11:17 PM

Seems like one person knows which are the correct syncros but they will not say

USMCram · 10-06-2019, 09:21 PM

Bumping this guy up. Have 5th gear grinds. Would like to get some more info.

Spooler · 10-06-2019, 09:34 PM

It would be nice to know if he has a forged (billet) input shaft for us boosted folks who break them.

Wezzley · 04-17-2020, 11:01 AM

Bumping this up.

I have my old transmission apart, lost 5th and 6th. Found the shift fork rod was completely sheared. A few gears were grinding prior. I put a brand new trans from Nissan in however I would like to build my old transmission for high power and reliability as this car is becoming a dedicated competitive drift car.

I have found ZERO information on where to get any upgraded internals available after reading through this entire thread. Some guy from Carver Motorsport or something like that?
