Can i get the CAR TRANSMISSION replaced here?

I got a 10year old ford car.mercury sable
have 150k miles in it… Just got a transmission issue…
the local mechanic, who has some great reveiws, says it requires rebuilt and gives 6 months warranty.
and says, if all goes fine, this transmisssion can go for next 150k miles.
he quotes 2300 for this… Is it worth to take the risk.
i can't afford to buy another car now. Even a used one.

If you think you can trust the mechanic, then do it. A rebuild is an expensive process because it takes them many hours of labor to do the job. If you don't think you can trust the mechanic, take it somewhere else for a second opinion (and another quote). Don't tell them what the first mechanic said because that can prompt them to say the same thing.

Find a shop that deals with transmissions only. They will likely be able to rebuild yours and give you a two year warranty. Your guy may be a great mechanic, but transmissions are better left to specialists. Go to atra.com or shops recommended by AAA are the highest rated.

Its a tough call.

6 months isn't a very long warranty. And $2300 is a bit high.

You say you can't afford another car, but can you afford 2300? What if a few months after you spend that kind of money, something else goes wrong? Before you make any kind of decision, look around for a cheaper price. I needed a new transmission for my 93 Camry recently, so I went to my old mechanic (in L.A., where nothing is cheap), and he said 1600, then I refused, 1200, and I got it done at a place my current mechanic knew about for 900. 2300 is more than the car is worth anyway.
