So i just bough the 02 4runner last week. 57k miles on it. The last 3 days its been downshifting into the lower gears real hard. Sometimes knocking into gear or a like thud. Also does this when i accelerate from a stop.

I have been reading alot of helpful things on the Message board. I took it down to the dealer where i bought it and they said it checks out fine. I do have a 3 month warranty. So they just might not wanna pay to do anything on it. Not sure if i trust the dealer

So i wanted to see if its wort getting my fluids changed.
1 - Flush transmission fluid
2 - Front and rear differential fluid
3 - oil change

Most likely 1 and 2 have never been done before... Is this a good idea? I hope it helps!

Thanks everyone.

Not sure if flushing or changing the fluid will help your shifting problem although a fluid and filter change wouldn't hurt.

Maybe have the filter/fluid change done at another dealership and also have them drive it and take a look at your issues.

If they find an issue take that to your purchasing dealer.

If the fluid level is fine (check it using the owners

Make sure you take a test drive with the mechanic to demonstrate the problem. That way they can't say that it could not be reproduced.
