DIY: ATF Flush, With Pics.

[johnnydd]

rich29 cal =stated he used Mercon V to flush his trans, My owners manual for my 2001 SR 5 V-8 says to use DEXRON 11 Or 111.
Does the 2002 use Mercon V? Someone with a 2001 that has flushed the transmission with mobil syt. what did you use?

M1 ATF Mercon V is understood to be compatible w/ Dex II or III. My '02 calls for Dex II or III and I used M1's Mercon V.

Lots of discussion on this issue here...

Awesome info guys. after I do the diff changes on the 4runner, this is next on both!

Can anyone tell me if the procedure is the same for flushing the trans on an 04 4Runner? (it has the factory cooler too).

I'm assuming the outlet on the top of the cooler is the return line to the trans, like the Tundra's?

Any other tips/ tricks for an 04 4Runner?? Do they have the screen in lieu of a traditional filter as well?

I am getting ready to do this and have a few questions:

1. My book says the volume of the ATF is about 2 qts with a drain and refill. I know there is some ATF left in the system but why does it take 12 more qts to flush it out? Is there THAt much still in there?

2. What about the gaskets Haynes mentions on the filter? You didn;t reference them so I wonder if they were in good shape?

3. When applying the gasket (on the pan), shouldn't you go both inboard and outboard of the screw holes to seal the screw?

4. After you reassemble the pan to the truck, should you let the RTV cure for an hour until it forms a skin before you refill and then flush?

Thanks for your comments. Your post with pics is great and I would not have even tried this without seeing how it's done.

Thanks, Baxter

1. Yes
2. Yes, mine was fine
3. Someone suggested in this thread somewhere that you should. Of course, I didn't and, knock on wood, no leaks so far.
4. Yes, the instructions for the RTV specifically says so. If I remember right, I waited longer than an hour.

Good Luck, let us know how it went.

Thanks, if it ever stops raining here in Seattle, I'll get this done...

Should the amount of oil you put back in after the drop the sane amount you got out?

Awesome job! I have to replace my cooler...its leaking/seaping from one of the spouts. I think Ill replace my fluid at the same time. Your pics and description really made it look easy!
Thanks!
