Thanks for the info. I took the car to the local Porsche shop yesterday and they're going to perform a fluid service on general principles. I told them to go ahead and take a sample of the fluid for lab analysis if they thought it was worth it and I would pay the extra.

Question about the failure mode of the torque converter - if the lockup clutch fails will the car leave me stranded on the side of the road? My inclination on my new-to-me 100k mile Boxster is to drive it until it totally fails. Right now the car drives fine once it warms up - nice firm shifts and solid lock up. Maybe I'll be lucky and the service alone will correct it but if it doens't is there any harm or risk from driving it with a weak torque converter?
