Trans fluid change advice/help?

[RichR]

Just rolled 10k and want to do fluid and filter to get out initial wear particles.
Does anyone now the model designation # of the trans in a v-8 4x4 Access cab Tundra.The place I get ATP kits only has 2k and T100 listings.I've had a few adventures with the 2 applications for Camrys,you dont know it not right until you've got it apart.
Does any one use ATP? I think they are the best.I will not use Beck-Arnely ever again/had a bad gasket detieration in 10k.Any help wuold be great,TIA

What is ATP? I get the impression that it is some kind of auto transmission filter and gasket kit. If that is the case, you don't need it. The 2000-2002 Tundra 4x4 A340F auto transmission has a drain plug for draining the fluid (4 quarts of it at least - you can't "drain" the fluid from the torque converter) and it doesn't have a filter per se. It uses a wire screen mesh filter on the pump suction and magnets in the bottom of the pan to catch any metallic particles. The filter and magnets only need to be cleaned, but due to the design, this should be a rare need. I don't think the maintenance schedule even lists a routine cleaning of the auto transmission filter screen or magnets.

Routine automatic transmission fluid drain and refill (4 quarts) should be more than adequate for a long life trouble free transmission, especially if you switch to synthetic ATF. I did a 4 quart fluid change to Mobil 1 Synthetic ATF at 10,000 miles and then again at 30,000 miles and will continue doing every 20,000-30,000 miles thereafter. I would do a transmission fluid change at least every 30,000 miles. Maybe at around 90,000 miles it would be worthwhile to drop the transmission pan to clean the screen and magnets. If you are towing heavy loads frequently it might be better to increase the frequency of these fluid changes and filter/magnet inspection.

regarding "2000-2002 Tundra 4x4 A340F auto transmission has a drain plug" - how about the 2002 tundra v8 4x2 auto transmission. Does the transmission on it have a drain plug as well?

Yes it has a drain plug, same scenario for the 4x2 tranny.

Yes ATP is a manufacturer of filter/gasket kits.I was told exactly what you are telling me by Toyota tech/partsmen.But I'm in there anyway to clean it out,and need a new gasket.I also feel better replacing the filter.
I have a 99 Camry I change the fluid/filter every 10k.40k so far so good.
I feel ATP has the best gaskets I've used.
Thanks for the trans designation!When I get a kit# I'll post it.
Sometimes the manual dont list some things you should do.No mention of the PCV vavle on the Camry.Happened to see it @39k and changed it.It was pretty gummed up.

The transmission "filter" is just a metal screen. Why don't just wash it off in some solvent and put it back in? Rather than aftermarket, I would just get a factory Toyota gasket for the pan.

Let us know what you find on your transmission screen and magnets.


By the way, 2wd Tundras use the A340E auto transmission. The only difference between the A340E and A340F is the tailshaft on the A340F allows mating to a 4x4 transfer case. And as far as I know, there have been no changes in transmission type on 2000-2002 Tundras or the upcoming 2003 models for that matter.

Good luck finding that gasket. After checking several parts stores and being told they didn't show any in their inventories, I begrudingly went to the Toyota dealership expecting to pay out the wazoo for a pan gasket. The fellow behind the counter looked a bit puzzled, checked his database, and finally told me he wished he could sell me one but he couldn't. Seems the Tundra transmission pan does not have a gasket! Just clean the mating surfaces really well, slather on some sealant, and bolt that puppy back on.

Good luck.

Shoot, that is even better. Just get a tube of that grey RTV silicon (OEM product for Mercedes and most imports - good stuff) at Autozone for about $3 and you are done.

I have been talking to SoCal company that makes aluminum transmission, differential, valve covers, etc. Replacement Transmission Pan would provide: Cooler Temp, Increased Fluid capacity, Mag Drain Plug and Temp Probe boss.
If there is enough interest they would start prototyping and tooling within the next month or so for our Tundras.

If interested reply to the poll "Transmission Pan" in the Engine & Drivetrain section

Just got home and popped the plug on the trans pan.I plan on letting it drain while I sleep.
I noticed the dipstick tube is part of the pan,and looks like it could be two pieces.Looks like a joint halfway up.
Is it two pieces?Or do I have to unbolt it and remove the whole thing?
I found ATP kit B-211 .The gasket looks like it lines up,I'll see this afternoon if the filter is the right thing.If any problems I will report back.

The lower part of the tube is part of the pan. The upper portion is a seperate part.

ok , The tundra does have a drain plug in pan, no there is not a gasket , it uses a sealer that does not become stiff, it remains pliable . Your local toyota dealer will gladly supply a tube for around the same cost as permatex sealers.
the dipstick is a 2 piece tube and is easily seperated by 1 14mm bolt.
As far as the filter just clean the metal screen with some brake clean product.
Just be careful when retightening the trans pan bolts, dont over tighten for they can and will break.

anyone know how much trans fluid it takes to refill the tundra tranny if you just pull the drain plug and put in some fresh fluid. thanks

3.75-4.00 quarts for a transmission drain and refill on my 2000 Tundra V8 auto 4x4. Others here have posted similar amounts. The owner's manual says something like a shade over 2 quarts - it's wrong.
