A bit of an odd questions, but hoping somebody can help. Friend of mine works at a general independent garage has an RX8 transmission in house they are looking to get rid of. (They brought in an engine to swap into a dead car, and it came with a trans.) I asked if he could identify which transmission it is, and all they sent me is the below. Any ideas from anybody? I googled the numbers on it but no luck. The reason for my question is, the engine they got in appeared to be a 4 port, with a manual transmission on it. So, I'm trying to figure out if this is a JDM 5 speed, a 6 speed some previous owned had swapped on to a formerly auto car, or something else.

 

Googling "R510K0" returns this result which calls it a 5MT.

Thanks! I swear I'm not hopeless. I googled that number several ways and got nothing useable. Appreciate it!
