Hello all! So I was able to dump the ROM from my RE5R05A transmission in my 350z by using Nisprog. Dumping and flashing to the ECU on our Z's is done using a VAG-COM cable which goes through the K-line. The TCM dump was done using the same VAG-COM cable through K-line.

I'll attach the dump below if anyone would be interested in checking it out! But we have access to the dump, but now it's trying to find a way to flash back onto the TCM. Here's the information I have so far;
Bosch GS19
MPC555 CC_OFF
BB020209.BDM_RBerk
1270H00114
ERCOSEK V3.0.11 OAK (C) ETAS Feb-25-2000
DAC14932
CF40ARX1596 (CF40A is the ECUID for the TCM)

For my Z, the TCM is contacted through the K-line which is also what NIssan's Consult protocol goes through. Does anyone know how to flash onto a TCM like this or have any advice on figuring out how to flash onto it? (Flashing is supported for sure)

I am pretty inexperienced when it comes to figure out how to flash to a TCM so I'm hoping that some people who have much more knowledge than I will be able to chip in!
