Transmission fluid change part numbers
I thought it would be a good place to document part numbers for parts needed when performing a transmission fluid change. Not all parts would be needed, but in the event of a stripped plug, or damaged pan or gasket, a part number would be nice to have. I'm not 100% sure on these part numbers, so any confirmation would be helpful. I'll update the first post as needed.
Transmission pan 35106-30260
Pan gasket 35168-60010
Filter (AWD) 35330-30080
Filter (RWD) ???
Drain plug 90341-10011 (need confirmation)
Drain plug washer 35178-30010
Level plug 90341-10021 (need confirmation)
Level plug washer 35178-30010
Fill plug ???

One comment on the fill plug "washer" which is an o-ring. The fill plug appears to be identical to the V6 Camry 2007-2011 fill plug and that gets a flat aluminum crush washer however the part Lexus had for the GS transmission is this o-ring. I don't know why but that's what it is.

I think it would be a good idea to document which vehicle you're talking about here. I speak with no authority but my research has turned up at least 6 different transmissions in the 4GS250/350/450 range. The 2012-2013 model GS350s with the A760E 6 speed have a different gearbox to the facelifted model with the AA81E 8 speed and the AWD popular in the north has a A760H. The part # may well be the same, just thought it was worth noting. Your RWD part numbers look spot on, they match mine. It appears that I forgot to order the fill oring..dang!
I found these torque settings for the A760E
AT drain plug 20nm
AT refill 39nm

My 2013 GS 350 does not recommend replacement of the transmission fluid - only to inspect: 'Transmission for signs of leakage' through 150,000 miles.

Lexus Australia doesn't mandate auto services but they do recommend them every 75000kms. I'm only guessing but given how differently the vehicles are positioned on opposite sides of the globe, Lexus USA went with the 'sealed' angle to reduce the 'cost of ownership'.

That's rather scary. Lexus USA is doing their customers a disservice, in the notes section your service booklet states that the transmission is a sealed unit and not to be serviced.

I would wager the percentage of high mileage owners coughing up to have their old cars serviced by a Lexus dealership is pretty low. I would have paid 10% of the car's value to get it's last major service.
We could probably get good life out of the engine if we increased the oil change intervals out to 25000kms. The fact is there is old oil with broken down additives. I haven't searched through the 3GS forums but I'm sure they're having issues with their transmissions as they age - some of us share the same transmission.
