I tried 1/3 bottle of this in both my 01 V70 T5 and 01 V70XC at 123k and 100k miles respectively. It seems to help both tranny to run smoother.
The V70 T5 has random hard 2-1 downshifts which seems to be mostly gone.
The V70XC seems to have perfect shifts from P-R and R-D. I recall some hard shifts periodically before. Nothing bad but now it seems to be incredibly smooth.
If you still have shift problems after ATF flush, B4 servo (some models), replaced broken lower torque mount bushing, and have the latest TCM software installed, you might try this before a valve body or transmission replacement.
