Transmission Flush supplies

Alright, as part of my 4R's refresh project I am going to have the transmission flushed with new fluid. I've been trying to figure out what I need but the information seems limited...

What parts do I need? Any gaskets, washers? The filter? Does anyone know the part numbers for them? What fluid does she need?

 

Try a search. There are a few well documented threads on this. Also at the other T4R site.

A flush requires the pan to be in place. A flush does not require the pan to be removed and does not require gaskets.

Get the fluid from the Toyota dealer. ATF WS for the 4th gen.

I just did the 4qt pan drain, pan gaskets, metal screen and o-ring. All good. A flush is a 12-15 qt event and requires opening the trans cooler lines.

 

I've found information on the 4th gens, but not he 3rd. Do the 3rd's use WS or that Toyota IV? And I do want to drop the pan and to have the filter changed, so I presume there is a gasket that would need to be replaced and maybe some crush washers?

I will check the other site.

 

How'd it with the flush? Where did you find the info? I'm thinking about doing a flush on my 2002 4runner soon and would appreciate any help. Thank you

 

Older thread so they may not come in to reply.

The Aisin A340 uses FIPG, though if you opt to remove the pan, you'll see replacement gaskets sold by various retailers.

Personally I'd recommend you use FIPG instead of a gasket, since that's what the factory used and its lasted many of us over 200k miles.

The filter is easily removed with just a few bolts after you remove the pan. Since there are often 2 replacement type filters, I would suggest you buy both from an auto parts store, and return the unused filter. I opted to simply clean mine with brake cleaner as the filter is really just a mesh screen.

Make sure you have a scraper tool so you can remove the old FIPG from the transmission and pan itself.

Here's a pic of when I did it on my Tacoma (same transmission) -



And here's your part number for the FIPG -

 

That Tacoma filter is not the same as my 2002 4R 4wd. Either get both or the TOYOTA parts counter will get the right one for your VIN. I don't recommend aftermarket.

Also, a traditional "flush" is not recommended. A flush is something the dealer or the Jiffy Lube guys will do with their machines. You want to exchange the fluid via the transmission cooler line. That lets the tranny pump fluid at its own speed. Look up the Timmy Youtube video where he does it. His vids are great because they are like 4R for Dummies and he explains everything. He also rips open an old filter and his verdict is DO NOT CLEAN THEM AND TRY TO REUSE.

If that filter has never been replaced, it's time to do it. While you have the pan out, check for shavings. I had 250k miles on my transmission and it had NEVER been flushed. The fluid was black as used oil. I expected shavings everywhere but there was nothing more than a bit of dust in my pan. If you see shavings...the amount will give you an indication on what life is left.

I went with the Felpro gasket. While I agree that the TOYOTA sealant is super great stuff, I didn't want to clean off an replace bunch of sealant if I need to get in the thing again. The age of these things will probably require getting back in there again.

 

Ya I just drain two quarts when I change the oil. Top it off with two quarts of fluid through the dipstick tube. Good to go....

 

Thank you for recommending timmy the tool man, his videos are very detailed. I'm going with his method but I was wondering what oil should I go with? Either valvoline brand or transmission oil from the dealer?

 

This is what I will do going forward now that I did a full replacement and changed the filter. If you do it every or every other oil change, it should be enough to keep the fluid fresh.
