Good source for genuine T-IV fluid - RockAuto
 

Yesterday I picked up a very clean Volvo XC70 as a driver and ski car for myself. It uses an Aisin transmission and T-IV fluid. I was looking around again for 10 or 12 more quarts of T-IV or equivalent shall I need to flush it based upon what I find/last service date. Usually Summit Racing is a good source as they have Mobil JWS3309 in 6 qt cases affordably.

I found RockAuto now has Aisin T-IV for $4.84 before the ubiquitous 5% discount. Shipping was very reasonable, 10 qts from Texas to Seattle was ~$11.00:

At these prices, using MaxLife or other less ideal fluids makes no sense - these units do run better on T-IV/3309 from my experience and also that of others.
