2010 CX-9 Transmission needs replacement

My 2010 CX-9 has about 70K miles on it. Couple of weeks ago, the engine and AT light came after I was driving back from the dealer after an oil change + break fluid flush + Coolant flush. The dealer flushed the transmission fluid (it was one of their recommendation which I declined before the problem occurred) which fixed the problem only for few days but now it has resurfaced. The dealer is now telling me that the transmission needs to be changed and quoted me a price of about $5K including labor. Few questions:

1. The light came after the work was done so am I right to be suspicious on the timing of the problem ?

timing seems suspicious, but the work that you did get done (oil change + break fluid flush + Coolant flush) should should not have triggered AT light. so it might just be bad luck, you're in NJ, I would assume you have AWD for Jersey winters ? if so, have you serviced the transfer case ever ?


2. Is 5K reasonable ? I live in NJ.

seems a bit high, most transmission avg about $3500 to $4000


3. I am not entirely convinced that replacing the transmission will solve the problem. I guess it reflects the fact that I do not fully trust the dealer. I am thinking of trading-in for a relatively used car but afraid that I may not get a good deal due to the pre-existing condition. Should I take a chance on replacing the transmission ?

Agreed, need to find root cause first before throwing money at the unknown problem, I bet it's the transfer case if you have one.

They might have disconnected a trans sensor which is why the light is on and you are having problems. Try to find someone you trust for a second opinion

Yes, I do have AWD. I don't recall getting transfer case serviced.

Thanks for your response.
