stevon Hi I'm having trans issues with my 2006 S40, I've heard some models you have to reset the trans after transmission oil change, Is this correct?
Philia_Bear not explicitly required on an 06 S40 unless you have replaced components as well as the fluid What issues are you facing?
Philia_Bear How many km since fluid change and was there any change post fluid change? Have you inspected the lower rear engine torque mount for wear?
