my honda hr215 hma  quit self propelling.   There was no oil showing on the dip stick.   I added 2 ounces and dip stick reads full.   I need to how to bleed the transmission.  I understand there is an involved process to do this.  there were no sign of a oil leak anywhere on the transmission.  It was working when I put it away in the fall.   I'm sure it needs more oil than i put in.
