Piston Slap: The Snow, The Lease And The Tranny

I lease a 2008 Mazda3 2.3L with an automatic transmission and 30K miles. I have had the car for two years and have been very satisfied. I am strongly considering buying the car at lease end. Here is the problem. After one year of ownership, I got stuck in some snow and needed to aggressively rock the car free. It took so long to free the car that the transmission temporarily failed.

I put it in reverse and just revs – no power to the wheels. Then I put it in drive – same result. I assumed that I overheated the transmission fluid and let it rest for two hours. I went back to the vehicle after it cooled down and it worked perfectly. It has worked perfectly since, with no noticeable damage. I recently brought the car to the dealer for an unrelated warranty repair and the service advisor recommended a transmission fluid change. He said the fluid looked dark and needed to be changed. He knew nothing of my snow escapade. My question is – Has the transmission been damaged badly enough that purchasing this car would be a mistake? Would a transmission fluid change be enough to mitigate the damage I caused? Do I buy the car at lease end or turn it in and run away?

  • 28-Cars-Later I cannot remember what happens now, but there are whiteblocks in this period which develop a "tick" like sound which indicates they are toast (maybe head gasket?). Ten or so years ago I looked at an '03 or '04 S60 (I forget why) and I brought my Volvo indy along to tell me if it was worth my time - it ticked and that's when I learned this. This XC90 is probably worth about $300 as it sits, not kidding, and it will cost you conservatively $2500 for an engine swap (all the ones I see on car-part.com have north of 130K miles starting at $1,100 and that's not including freight to a shop, shop labor, other internals to do such as timing belt while engine out etc).
  • 28-Cars-Later Ford reported it lost $132,000 for each of its 10,000 electric vehicles sold in the first quarter of 2024, according to CNN. The sales were down 20 percent from the first quarter of 2023 and would “drag down earnings for the company overall.”The losses include “hundreds of millions being spent on research and development of the next generation of EVs for Ford. Those investments are years away from paying off.” [if they ever are recouped] Ford is the only major carmaker breaking out EV numbers by themselves. But other marques likely suffer similar losses. https://www.zerohedge.com/political/fords-120000-loss-vehicle-shows-california-ev-goals-are-impossible Given these facts, how did Tesla ever produce anything in volume let alone profit?
