Hi,
I have a 2010 Corolla with about 65k miles on it, bought used about 5k miles ago.
Toyota dealership told me that my transmission fluid is old and has to be changed, which I thought it was odd since Toyota maintenance said it is a lifetime fluid.
So I decided to change it myself, with a regular drain and fill.
After draining I noticed the old fluid was very black. I refilled with almost 3 QT of new fluid.
After driving a few miles, the oil looks dirty again from the dipstick, all the old fluid mixed with the new one.
So what should I do now ?
- Do 2-3 more drain-and-fill again within 1-2 months until the fluid looks cleaner ?
- Flush the liquid and refill with new one by disconnecting the hose from the radiator (heavy and a little risky procedure)
I don't feel confident removing the transmission pan to clean it up now, I am thinking to do it at 100k miles.
Thanks for your advice
