Looking to change transmission fluid in our 2009 C70 auto. It is an AW55 so takes the JWS3309. Local dealer told me they use Pensoil Dex6 full synthetic and not even the Volvo branded oil.
Part I am bit stumped on is exactly which hose to disconnect to do the pump out method. Looks to have two challenges from the older cars here
1. The transmission oil cooler is slightly differently on this car as a rectangular box bolted to radiator. Seems the same old procedure of hooking up 1/2 hose to output, pumping out 2 quarts and refilling but the hose to bucket would need to be connected to the transmission cooler block instead of output off radiator

2. refilling; the dipstick tube looks rather difficult to access from above ..
