I did a drain and fill to get out the break in materials in the 4 speed auto tranny in my '13 Corolla with 15k. I did one drain and fill Of exactly 73 oz at 10k miles and today at 15k a second drain and fill of about 72oz as measured.
I use Toyota WS atf as i should. I keep all measuring tools clean and wiped out. I did today's drain and fill and took it for a spin. Up to operating temp. Shifted great/same. Fluid was slightly purple-pink rather than the bright pink of the new. I felt good that i got out the wear in materials out and fresh fluid in. All was well. I checked fluid level on a level surface at correct temp and procedure by the book. Official toyota procedures. No leaks. I even compared the temp of the fluid out to the new fluid going in and it was within 10F differential. I was god [censored] scientific abouy the whole thing.
Then after sitting for a half hour in 50F. I took her for a spin again and she shift FLARED on the first two stoplight accelerations through the 2-3 shift. Id say the flare was quick and a flare of about 150--200 rpm just momentarily. Then if shifted fine.
Did it do damage?
Is this a normal hiccup?
I checked the level again at operating temp and I'd say it is literally hust a hair below the way it read on the dipstick from the factory fill. There is two hot zone notches and it is just past the first notch.
Should i add an ounce or two more? Could a freaking ounce or two make for a shift flare when it cooled for just a half hour?
Im bewildered and scared to drive it tomorrow morn after it really cools and fluid contracts down to the 40F ambient here.
