Synthetic Transmission fluid questions
I have 2 questions regarding a Toyota Corolla with 146,000 miles.
1. I've heard that a tranny flush on a high mileage vehicle can cause problems with dislodged material. Is it risky to just drop the pan (or drain if there's a plug) and top off the fluid? Does that adequately refresh the fluid? Right now I don't have synthetic, but would like to go there - is it OK to mix synthetic with the non-synthetic that's already there?
2. Regarding the power steering fluid - same question about mixing non-synthetic with synthetic.
The specs on my Corolla say Dexron II for both the tranny and power steering.
Thanks!
