the only concern i think may be there when using a non at-temp method is possibly a density diff between the old and new oil. but from what i can see, very insignificant diff (if any at all).

Toyota would be wise to add a sight glass to the pan, then checking the level would be so much easier vs having to watch fluid fall out of a riser tube.
I dunno about that. The level check is done via the overflow tube, so whether you measured accurately or not, it's full when you get a dribble from the overflow tube (at the correct fluid temp). The fluid expands and contracts with temp, so getting the level exactly correct, DOES require the fluid be at the right temp IMO. They say these tranny's are sensitive to fluid level, so it's something I'd want to know was done right.

#1 will not get you a new filter, ............ you should get a new filter in there.

now, you have to be creative to pump in the oil, look around for the pumps that go onto the qt bottles, you need a fill hose that will fit snug into the check port, etc. you should plan to pump in 2-3 oz more than what you took out to account for minor spillage and not being able to get every drop out of the bottles, etc.

i have a thread somewhere with some pics, search for my posts, you should be able to find it.
appreciate the answer, but i wasn't asking about the engine oil change, i asked about changing the transmission oil!

thank you again for your time guys!

i dont even bring it to temp, i just drain and drop pan, measure what i have, and then put back the exact same amount. i used one of those transfer hand pumps from HF and this allowed me to turn bottle upside down so every drop got into the pump.
To get every last drop of fluid in the line into the transmission, I simply blew into the hose on the other end. Very scientific.

I did this the last last weekend and just want to say thank you to everyone who made this a diy thread. I dropped the pan and changed the filter/screen, cleaned the magnets and got about 5.5 quarts total with draining and dropping the pan. I did x2 more drain and fills which yielded about 3 quarts each. So, roughly 12 quarts total. Dropping the pan was a little more involved and required taking part of the exhaust off that crossed the pan. One question: does anyone know the percentage of new fluid is in there now? Thanks.

Just like to share a trick for tranny fluid refilling. I accidentally lost some tranny fluid when doing a radiator replacement work. This thread has good ideas of how to refill the tranny fluid. However, access to the tranny fill hole under the truck is tough. I just used this little trick to add tranny fluid. I removed the returning hose (the top one) of the tranny Oil Cooler in front of the GX. Pour the fluid into the hose. The fluid will return to the tranny through the cooling path. It slowly drains with gravity and needs patient. But it works.

how do you know how much you lost?
I lost about a quart. I did not check the exact refill. I guess to add oil from the refill hole, you need to use a pump. You can use this method to be accurate.

yeah, but car has to be at operating temp which is like 104 to 113 degrees before you do that top off.. The fluid expands as heated so this is a critical step

What about using a temperature gun to check trans temp? I saw a guy do this on a hyndai.

This is copied and pasted from the instructions.........."Connect terminals between CG (4) and TC (13) of
the DLC3 using SST (09843−18040)"



Do you just use a jumper wire connected to these terminals?

yes and then go through series of shifts , etc, watch for blinding light once at operating temp, which is when you top off. Once light is solid, it is above top off temp. Instructions are on this forum that go step by step. The fluid expands when heated and this is why this step is critical.

Blinding light?Where will I see that?Coming from the dash? Do you mean that the 'D" will become very bright?

Taday I did an oil change and was scoping out the transmission .I took some pics to make sure I have everything in order before I tackle this. The drain plug is easy,can you or someone else confirm the fill port and the over flow plug. I am confused because what I think is the over flow plug(its a hex fitting facing the ground,I thought it would be on the side of the pan).Its not much higher than the drain plug,is,that right? See pics below.

I see what I think is a fill plug on the side of the transmissin above the rear of the transmission pan. I put a socket on it and its 24mm,is that correct?
