A343F Fill Procedure?

Removing the old FIPG was the worst part. A flathead screwdriver on edge pulled back toward me was the best tool. I also used a razor blade scraper to get the big stuff off the ridge. It comes off the trans face much easier than off the pan.

For cleaning the pan, I used shop towels and Simple green to get the residual fluid out. Then I used MAF cleaner (won't leave residue) to wash it down. Make sure to spray some inside the dip tube and let it run into the pan. Finally use an air gun to blow out the tube and the remainder of the pan. The little magnets just sit back down into their valleys. Remember to turn the magnets up in the northern hemisphere and down below the equator. :)

The FIPG comes in a tube with a winder tool. Put the tool on the end and turn and it gives good flow control. Don't try to lace the new FIPG around the bolt holes. Just give a good solid bead, flatten it with your finger, re-apply if there are any gaps, and then punch through the bolt holes with a scrap bolt or screwdriver. The FIPG is going to squirm on re-install anyway.

Once started you have about a 10-15 minute window. So this would not be a good time to take a phone call or have a crying baby. Getting it back up onto the trans requires a little bit of planning: start with the rear portion first - you come up at an angle with the front sloped down. Once clear of the cross-member raise the front level and make contact with the pan. Have the bolts ready so you can start them immediately to hold the position. I started one on each side about mid-pan and it held it fine. Get the remainder started with the nut driver and finish off with the torque-wrench (a step I skipped).

Finally the flushing. First, fill the pan through the dipstick. I used a small funnel I have. It fits perfect in the mouth of the stick and had a canted opening - perfect for filling at an angle (no pic :frown:).

A full pan of fresh AFT is the start. Now you want to use the trans pump to push the remainder of the fluid through the TC and cooler to drain. To do so, you remove the return line near the bottom of the radiator as shown below. The correct line is the one on the passenger side directly below the alternator. The one just to the right is the supply from the trans. This trans pump is very effective; you'll get about a qt every 8-10 sec if you pull off the supply hose. :( There is more dynamic head going through the cooler so I'd roughly say about a qt every 15 sec out the return. Not shown, but I had a 2nd vice grip on the return above the coupling to the clear section to restrict flow. You don't need to pinch it much.

Connect a hose extension and drop into a bucket. Start the engine and watch about 1-1/2 qts come out. Shut down, refill, repeat. It would help to have a partner at this point and you might be able to do a continues flush without the need to stop/restart if the fill can keep up. You'd need to cautiously verify this on your own as you would not want to starve the trans pump. During this process, you'll want to cycle P-R-N-D-2-L to get all of the actuators purged.

I put a total of 14 qts of new Amsoil in before I stopped. After I reconnected the hose and checked the level running I needed to add about another 1-3/4 qts. So you'll want to have a minimum of 16 qts on hand.

Do also note that this requires removal of both front shields - the rear fiber plate and the front metal plate.

Correct line to disconnect:

Nice writeup.


The only thing I would add as someone who goes into his own A343F every year: if you have access to air and a die grinder, your ability to get the OEM FIPG off is significantly reduced with the grinder and a scotch brite pad. Clear FIPG in a few minutes with a grinder. The cleaner you make the mating surfaces the better.

As I saw at the factory, Toyota loves FIPG. And I don't blame them.

It's good s*** and well worth the money.

FAQ material.

Torque specs?

What are torque specs on the trans pan?

Great write up. The photos definitely help.

Does anyone happen to know the torque for a '99 transmission drain plug? I haven't come across for this year, just the newer years with the overflow plug.

Thanks!

I got mine :banana:tight. Honestly, I have no idea the correct torque. You just need to get it tight enough to deform the crush washer a little. About the same was what you'd do for your oilpan drain.
 
Thanks OregonLC

Just wanted to say thanks to OregonLC for such an informative and helpful post.

Did my AT fluid exchange today (w/o dropping the pan - didn't want to mess with or have the time to do the FIPG). I did the pan drain and then attached a 5' long tube to the hose shown in OrgeonLC's pics and a gallon container inside a 5 gallon bucket - no mess - no spills whatsover. The 5' hose allowed me to stay close to the drivers seat and the ignition as I did this by myself and ran a quart and a half through and then shut the engine off to refill an equal amount.

I followed the thread almost to the letter; even pinched the hose so as to slow the fluid exchange. A very clever idea!

Taking OregonLc's advice I was cautious and only exchanged 1 1/2 quarts before topping off so as not to starve the trans pump.

I am confident this excellent thread not only saved me time but also frustration from wondering if I was doing things correctly. I printed the thread with pics.

Anyway, thanks again OregonLC!:cheers:

Glad it worked well for you! How did your fluid look coming out? Any chance you reserved a sample to send off to Blackstone Labs?
 
I could see a noticeable difference between the old fluid - reddish brown but more dark brown and the new deep red Amsoil Synthectic. I didn't think about a having a sample ananlyzed as I have a tendecy towards OCD :) and didn't want another thing to worry about. That's why I have AAA.:)

I did notice smoother shifts, an obvious added plus. I'm anxious to see how cold weather starts are now.

When I have more time I'll drop the pan and clean the magnets. I took Beno's advice and purchased a die grinder to make short work of the old FIPG.
 
For those looking to do this, the one thing I would ask is that if at all possible you send a sample into Blackstone. Would really like to get some data points on what is normal for the LC A343F.
 
[STRIKE]Are the cooler lines 3/8" internal diameter?[/STRIKE]

The cooler lines are 3/8" internal diameter.

I did this a few days ago. Drove it for the first time today. It shifts much smoother now. I took out 12qts plus whatever spilled at the beginning. I put 13qts of Mobil1 D/M ATF (~$3ea at Target of all places) back in. and after driving to work today, the dip stick reads right at the cold notch. I'll add .25-.5qts when I get home and see how that does.

If I were to do this again, I'd run a second hose from the transmission inlet nipple into the bottle of fresh ATF. Theoretically, it would suck up the new ATF at the same rate that the cooler line is squirting it out.

Anyone done that? I might try it with my exchange this weekend.
 
Does anyone know the part number for both the transmission drain plug, and the plug gasket for a 1999 LX 470?

Someone posted this number: 35178-30010 for a 2005, but they use a different transmission. Anyone know?

From toyodiy for the '99 LC:
drain plug: 90341-10006
drain plug gasket: 35178-30010

So yes, it happens to be the same parts for the drain plug and drain plug gasket for 99 or 2005 despite having different transmissions.
Also you can plug in those numbers to toyotapartszone (as an example) and it will show you the applicable vehicles (click show all 'cause it's a long list) and you'll see the various LC100 models come up in there for these 2 parts.

This isn't stickied in the FAQ yet, but it really should be.

E? Trunk?

Great write up. The photos definitely help.

A bit late on the draw here, but the torque specs for the transmission pan bolts ar 65 in*lbf, or about 5.4 ft*lbf.
The drain plug is 15 ft*lbf, as mentioned earlier in this thread.

Thanks for this write up. I changed my fluid and the shifts are noticeably smoother!
 
I realize this is an old thread, however I wanted to let you know it is still being appreciated.

Being a visual person, I would like to thank you for the picture of which line to disconnect. I have the fsm, but a picture from the actual job is worth so much more.
