I have a 2005 Toyota Camry with original OEM transmission fluid in it, it’s at 150,000+ miles. Should I change it? I have read that if your fluid has never been changed and you have high miles, you can do more harm than good by changing your fluid. I’m long over do, so should I just leave it alone?
I checked the dip stick, and to my surprise, the fluid is very red! It’s not black or burnt at all, looks very clean. I’ve heard that if it’s long over due and your fluid is black and disgusting, just leave it alone, new transmission fluid will flush out all the debris and you’ll loose friction etc…
So I seem to be in the situation were I’m way WAY WAY overdue on changing the fluid (150,000 miles, 15 years old), but the fluid is still red and looks clean!
Should I go ahead and change it or would I be doing more harm than good?
I think the original owner neglected servicing it because in the maintenance manual, it doesn’t even call it out at a certain miles, at all in the Chilton maintenance book.
