Ok I'm trying to identify what transmission is in my car it's a b18c motor and has a 6 speed which everything I read that this is impossible unless you buy an Expensive aftermarket market one I checked numbers on block and head and it is definitely jdm b18c

Honda never made a 6 speed transmission in a b series. There was a H powered car with a modified setup and running a 6 speed long ago.
