Could be a hunk of lint or thread on the blower fan or a piece of paper or such caught in the fan or where the blower fan hits or comes real close to it so making for severe airflow disturbance (causing the whine), or the motor or fan blade mounting bolts loosened up and it is just nicking the housing - but at that age I would say likely shot bearings on the motor because Trane motors tend to have a pretty short life - 10-15 years from my experience, as opposed to some high quality brands like Carrier that can commonly go at least several decades.

Depending on model and general accessibility to the furnace and especially on whether an integrated motor-blower or not and also highly dependent on whether a multi-speed or continuously variable speed motor or not, could run anywhere from about $75-150 if motor does not need replacement, commonly more like $60-300 for after-market or $200-600 for OEM Trane motor (or combined motor blower in some brands and models), plus commonly around $150-300 labor to replace it. If the control module for it (if multi-speed or variable-speed unit) could add another few hundred $ real quick.

However, there are horror stories out there about labor charges of over $1000 for blower replacements - I saw one case like that which a neighbor asked me to give an after-the-fact opinion on, where the blower motor was front-mounted with 2 pull-off wiring harnesses and 4 sheet metal screws - a 5 minute max job to replace, so if the price quote comes in real high get competing quotes from other providers. I would say for normal single-speed fan replacement probably $300-500 range would be the normal range, and maybe $500-800 if multi or variable speed unit.

And no - lubricating it is generally is not an option on a motor under about 20 years old unless you disassemble the motor and do it yourself. Most techs these days are "plug in the part" guys, not repairmen - plus manufacturers in their greed for bucks from replacement parts usually no longer provide greasable/oilable or readily replaceable bearings or bushings even though that is almost always very easy to do in the design stage, so now when bearings/bushings go out replacement of the entire item is the norm, at much higher cost of course. This is pretty much true of all appliances and even many parts on cars these days.

Heating and AC would be the Search the List category for a technician to do this repair - and don't leave it for long, because it can go from whine to failure in as little as a few days - though sometimes it will go for years also, you never know.
