Manual, yes.
An auto the F23 uses has the ecu for the engine and trans on the same one. H22's do not... So I don't know if you could put on an h22 auto, use the manual f23 ecu and h22 auto trans computer... Or not. It makes sense but either way getting another auto is kinda taking a step forward that will eventually just go back. A manual will take a step forward, and stay forward.
