I drive a 2011 RX350 with 180k miles. Had a transmission flush and fluid exchange, had to drive 8 hours afterward for business. 20 miles down the highway I got a message on my dash that the trans fluid temp was too high, pulled off on the side of the road and let it cool. I figured the trans just made a new friend for the first time and had to work it in so I cruise controlled at 65 for the 4 hours up. Halfway through my way back after spending the night (6hours in) acceleration got very sluggish, took forever to get up past 55, and I’m not sure the car will let me past third gear but I don’t know much about cars so I’m not sure. Made it home. Advice?
I think a phone call to the dealer enquiring about the recommended fluid would be helpful. Ask what they think about MV. It may be fine.
