Almost a year (last December) I changed the transmission fluid using the Valvoline Max on my Lexus RX300. Everything seemed fine untill a week ago. When I shift, I felt a jolt (or jerk however you say it) and there was no Check Engine light on. So I decided to change the fluid using the Toyota Type I-V, about one gallon +. The jolt disappear since. My guess is that although the Valvoline Max claimed to be compatible with the Toyota one, maybe only for 10 months or less than 1000 miles. I wouldn‘t do it again next time, just for the sake of saving a few bucks.

This thread was about the power steering rack leaking. I don't know how transmissions even entered the conversation.
I would NEVER use anything but Toyota T-IV transmission fluid in my transmission. In the power steering, Toyota requires DEXRON III ATF. Valvoline Max Life is a synthetic DEXRON III ATF that CAN be used in the Sienna's power steering system.
