I just bought a 2002 S60 Base Model Non Turbo..When I Accelerate The Car Hesitates And Lags sometimes i changed all 5 coils and spark plugs seem to be in check. what could be the problem? Also when i put the car in gear such a drive or reverse the car jerk's could this be my trans? it only does it sometimes.. pls help thanks - AMVO

 

There was a transmission software upgrade. Could be that your's hasn't had it done yet.

 

Ok so how would i obtain this upgrade ?

 

Probably have to go to a dealer and let them put it on the computer and see if it's been done. When I had my S60 there was a lag sometimes and the software update took care of my problem.
