I have a G35x and I need to replace my TCM/valve body.
I came across a M35 TCM/valve body which appears to be a match on the TCM, however I have a question about some markings on the valve body?

This is the valve body from the M35 (possible replacement) What is MCA #2 ? Compared to MCA #1

Just to make sure you're aware, the TCM and valve body are two completely different parts and there's usually no reason to replace them both unless both have failed. If there's nothing wrong with your TCM then just keep it and swap it to the replacement valve body, or vice versa.

You can also just replace all the solenoids on the valve body if that's the only thing wrong with them. You can buy them as a kit or individual.

 

Also check out these two pages on the Sonnax site about the various valve body configurations for the RE5R05A so you can figure out exactly which one you're dealing with.

You can buy replacement rebuilt Sonnax valve bodies through Rockauto if you order by part number, I think they're $300 plus shipping.
