Yeah, do more than one but spread 'em out. I have no idea if it should be 500 miles apart, 5000 miles, etc though (no one does!).Yes do a drain and fill. As already mentioned do several of them but well spaced out with correct fluid.
Use the Toyota oem fluid from your dealership. Ask the dealership whether to change 1/2 or all.the transmission fluid has never been changed. Recently i feel the transmission slipping . Should i changed the fluid completely or just a partial change of fluid. The fluid looks more dark than red. any other ideas
This is what i'd do also.I would do a full exchange, then again after 5k.
If the trans is damaged, it is damaged. Doing a bunch of D&F to be “easy” on the trans won’t change any existing damage at this point.
Changing the fluid at this point likely will cause more slippage. Your tranny had a good life but it's on borrowed time.the transmission fluid has never been changed.

This is an 03 Camry with 300k miles. Sure, to the $300 flush, but the cars not worth throwing a new tranny in imo, at least in my area a rebuilt tranny and labor is worth more than the car.It a misconception about only doing a FILTER service on a automatic transmission. Dilution of fluid does not work because you are still contaminating the remaining larger amount of fluid that is still in the transmission . If it is starting to slips with that many miles dropping the pan will not really tell you to much because what you WILL FIND in the pan and filter there is not really a way to indicate how long its been there?
The only real way is to have a specialized Transmission shop do a complete evaluation which would and should include a basic filter, electrical component test and pressure testing . They may if they determine that the material in your pan is more then say 50% of the clutch friction material and not large chunks of something like metal of friction disc materiel (lol) do a complete replacement of fluid. The procedure is about 300 at our shop. In your case if you were my customer I would first recommend to shop for a rebuilt or guaranteed low mileage transmission replacement. This way you can think about what is going to be the best option for you.
I dont even recommend an oil analysis because of the history of none maintenance and that it is starting to fail signs.
