Seeing as you've provided no details, you cannot expect more than just general advice. That said, probation screams either a serious onetime infraction or a pattern of sub-par behavior.
Your program is concerned about your ability to thrive on your own. I would treat this as purgatory, halfway between redemption and getting your @$$ booted to the curb. Looking at it from a stakeholders perspective:
-Program perspective: Probation shows they still want to invest in you--which they should as it's a pain/risk to replace a resident, looks bad for the program, and can damage morale in the class. At the same time, their enthusiasm to retain you will be in part predicated on whether you are felt to be capable of completing the program and eventually passing your ABIM exam. Your PD doesn't want to waste their time or yours. For them, this is the ideal time to interview for your replacement (they will be at a disadvantage if they start looking in March). Further, if you fail your boards after barely squeaking by, you will hurt the program's pass rate metrics. In other words, they are taking somewhat of a risk by giving you a chance.
-Your perspective: Forget about transferring to a different program. You would be forfeiting your current spot in order to apply at a disadvantage elsewhere (late in the cycle, other red flags on record, lack of institutional support). Treat this residency as your lifeline, and don't screw it up. This means get your **** together and act like a model resident. no complaining, arguing, tardiness, laziness or ego. Touch base frequently with your PD and chief residents so they can see your effort. Remember, the decisions you make over the next half-year may determine whether or not you will ever be able to pay off your student debts, own a house, or earn a physician's salary--How much are you willing to sacrifice in order to earn 250K-350K/year as a board-certified physician vs 30K/year working overtime as the most educated employee at Macy's? I know it's stressful but it should be.
