Got an 04 330 just hit 140k miles. Transmission was serviced at around 80-90k miles. Want to change transmission fluid now. Would a drain a fill be sufficient? Or should I drop the pan and change the filter out? The fluid is getting quite dark small hint or red mostly dark though.

with filter

i would just drain and fill.

I would replace the filter and pan gaskets as well. Probably cost no more than $60 online.

I replaced both in my wife's 08 RX350 at 115K miles. I also do a drain/refill every year religious (~10K miles). Now at 135K miles and the car still shift very smooth.

06 RX330 245,000km, Drain and fill only every 50,000km still running smooth. Do 2nd time within a few days if you hate dark colour.

I do the drain and fill at every oil change when my oil was dark until the situation stabilized. I bought a vacuum pump from Amazon to do this so I don't need to remove any drain plug and get a new washer. I do this while I am doing the oil change so I get a head start... I know it isn't perfect ...

With the vacuum pump, you can also replace all the steering fluid and replenish with fresh fluid. The steering system uses the same ATF fluid...

Automatic transmission fluid exchanges every 30k since purchased new, currently at 248,700 miles. Never touched the filter or pan. Solid vehicle.

I had filter changed at 180,000. Pan was very clean, no shavings at all, filter was still ok. Doesn't seem like it was necessary in my case. I do d&f everyb10k miles, seems like that was worth it.

Drain and fill, proven reliable. Toyota uses WS Transmission oil now. But the Type T-IV is still available.

Never done the filter, just drain and fills after 100k. Wish I had started sooner, but still runs/shifts perfectly.

Had to replace the transmission and I updated the planetary with hardened gears also welded the caps on the planetary gears this is what causes the trans to go out.
Using Valvoline MAX-LIFE full synthetic transmission fluid and also in the power steering added transmission cooler for the So Cal hot weather.
What I meant above the caps come loose on the planetary gears and the bearings get loose and this causes the trans to fail.
The reason I use synthetic trans fluid had 3 cars go 529,000 405,000 and 300,000 miles and all the trans went the distance including the power steering.
I change the oil at 20k and the filter at 40k I now have 187,000 on my 2001 RX 300 going for 300,000, I use the new Mobil 1 annual in the engine change it at 15,000 miles.
