I am using my 5AT ECM. Do you think re flashing the ECM to 6MT would fix the PNP and reverse switches, or just get rid of the U1000?

 

I've never done it before, talk to @seymore4 he would probably know.

I'm pretty sure that's the problem though, the 5AT ECM is looking for a TCM which isn't connected thus U1000, P1065 might actually be sent because of "no power to TCM".

 

There could be something else going on, but at minimum you need to flash the ECU for the 6MT swap. The ECU thinks its an automatic still so its going to give you all kinds of problems . I'll send you a PM

 

Did you ever get your G sorted @FrankenG I did a 6 speed swap in my 03 sedan begining of this year, and was not so lucky to just send the ECU to get an Uprev tune. My ECU is the half year that is not supported....lame.

 

@southdown The reverse lights are easy enough to hard wire, and once I got the car tuned to MT the cruise started working even without the pnp hooked up. I don’t think you’ll be able to get it working if you can’t tune it

 

I have the auto trans still and currently doing the cd009 gen 2 swap into my 04 g35 sedan. Thinking I can just pull the tcm from the trans, plug it into the wiring, zip tie it to the side of the manual trans and as long as it sees neutral safety and shift lock it should work like an automatic motor to a manual trans, only thing is, it will think it’s in a different gear than it’s actually in and won’t adjust the iac accordingly when I push the clutch in. Usually there’s an increase in rpm because the car goes into idle mode between shifts and changes the torque stall speed to match the shifting revs. So when I push the clutch in to shift, it’ll either think it’s in let’s say, park or drive and continue the motor at it’s course instead of reacting to each shift like a manual ecu would. Anybody know how true this would be, or have an alternate solution that doesn’t require buying an ecu or reflashing one?

 

The car will probably just limp mode because it won't see the turbine input/output speed data and will think the transmission is slipping or not functioning.

 

Just get the ECU flashed for the manual swap. It will make your life so much simpler

 

Hey man what’s up? I just bought a 2004 Infiniti G35 2 days ago and I just found out yesterday that it was converted to manual and my reverse lights don’t light up when in reverse and also getting a P1706 (park/neutral position switch) and a U1001 (controller area network line malfunction) along with other codes. I’ve only been in the g35 game for about 4 months with my last G35 but it was auto. Please any information on how to get the reverse lights to work will be helpful like as description on where I can locate these sensors and how to run any type of wire. Thanks man 👍
