Dealer found transmission leaks on first oil change to my 2016 MDX, saying it was a faulty end-cover sealing gasket. This is, however, not what I am asking about here. Dealer called me today saying that Acura hasn't sent dealers the proper tool to replace the gasket yet, so instead they will need to replace the whole transmission. Insane, right? To be honest, I don't know how to think about this. It will be at their cost and apparently it will be a new transmission. On the other hand, my MDX only has 4k miles on it and it runs great. There is potential risk with such repair, and I don't even know what kind of impact to the car's resell value (it will show up as a major repair on record). Should I push hard to not have the transmission replaced, or do you guys think this is not a big deal?
