hello have a 2002 taurus ses with about 34000 miles on it. 2 months ago got a transmission fluid flush around 30000 miles i follow the maintenance book. just got an oil change today and in the past week and a half when the speedometer get to 45 miles per hour theres a lot of vibration, hesitation to accelerate and the tachometer flies up to 3000 then back down to 2000. at the mechanics today they told me a half shaft is broke, or leaking. and that the transmission fluid smelt very bad, burnt. they drove it and felt transmission slippage also. whats a transaxle? how does that go hand in hand with the transmission? which company would be responsible for any damage to my car? place i got the transmission flush 2 months ago?
