hi your sts has a 4t80e transmission.this is a complete electronic transmission.this has to go in and have the electronics tested first.this car could also be in limp mode,designed to make you take the car into be tested and repaired.with electronics just because the trans.is acting up doesnt mean its the trans.engine performance or electronics can affect the trans. as well.your freewheeling is because of transmission design,put it in manual low and then lift your foot,should have no freewheeling then.

you have burnt out the 3rd. gear and overdrive. you will have to have it rebuilt or replaced.
A common problem with alot of Volvo's is the Overdrive. Basically the high gear. If it wont shift into high gear it means that the "Overdrive" is activated and won't shift into high gear. You need to see if there is a little upwards pointing arrow on your Dashboard Cluster. If there is then you need to replace your Overdrive Solenoid.
Because it does not have an overdrive gear.
There is no overdrive, per se, but a mode switch called "Power Mode" that doubles as an overdrive, allowing more RPMs per gear.
if it is an automatic leave it in overdrive. the transmission knows when to change into the overdrive gear. if it is a manual listen to the motor. if you have in overdrive and it bogs down while accelerating then down shift to a lower gear.
