Are the old and new Toyota fluids fully compatible-- can you mix them in your system?
I have read about four long threads on sorting and tuning the AHC system on my '05 LX470 but I am not clear if the New fluid has been reformulated thus the newer part number- or if just the part number was changed.
I am going to perform a PADDO flush which flushes out a good portion of the old fluid - but perhaps not all.
I am not sure which fluid is in my system so I felt I better confirm.
