~50K Mile Transmission Fluid Change
Changed out the eCVT fluid again after ~50k miles on my '13 hybrid (150K mi). Just like the last time, I pretty much emptied the 5qt jug of Mercon LV into the case before it dribble out. Last time I went by measured height off the ground but this time I put the tire back on, lowered to the ground, ran for 1 min and let sit for 5 mins (per the service manual) before removing the fill plug and let it dribble out until it stopped. Capacity is 4.5 qts which is pretty much what went back in when I filled. I found that by lowering the car past ride height, an extra half qt or so drained out of the case.
After ~50K of mostly highway driving, the fluid was a darker in color than the new fluid and the highly scientific finger rub test was positive in demonstrating a loss of lubricity. Is 50K mi too frequent? Maybe. The last time I changed the fluid, it was much darker in color but I was also doing mostly city driving.
I'm not sure if my frequent changes have any impact on prolonging the life of the known flawed early build HF-35 or if I'm just wasting my time. I figure ~$50 and an hour of my time every 4-5 yrs is worth it so I hope to post again in another 50k mi.
