The engine and trans are out of my 57 Bird.   I think I have read where the trans can be modified to start in low and upshift to 2nd and high when the shifter is in the drive spot, making it always use all three speeds and operate like a newer transmission.   Can these modifications be done?   The trans will be rebuilt by a local shop, but I would like to know if this can be done before taking it in.   If this has been posted before please redirect me.   Thanks in advance.   J
