I have 2012 XC70 T6 with 85k miles and so far love it. Overall the car runs and drives great, great MPGs.
Just one odd thing, at low speed, if I am off the throttle or at part throttle ( like coasting to a corner, in a neighborhood, or in a parking lot ) and I return to give the car gas to accelerate there is a very brief lag or hesitation before the transmission seems to hook up and start to accelerate. Sort of make it a little jerky, even with gentle throttle.
Reminds me of an older car with an auto trans a quart low on fluid and cold.
Any experience here? I hear all sorts of advice on these cars with trans fluid flushes, so I don't know if that is a possibility or if it could be software.
