Fluid replacement for gearbox

[Howard_silver]

Greetings, greetings, I am preparing to replace the gearbox fluid in my 24 Crown Limited and would appreciate any guidance or resources on the procedure. I have viewed several videos regarding gearbox service for various Toyota hybrids (specifically Car Care Nut's video) and for the latest 25+ Camry, and I am curious if the identical procedure is applicable to the Crown. I was curious about the exact amount of total fluid required for a standard drain and fill without performing a flush. I will undertake this task with my father, who possesses extensive mechanical expertise, yet I still wish to be adequately prepared. I appreciate your assistance in advance.

If you possess a hybrid, which I presume you do, 1. what is the rationale for implementing it on a 2024 vehicle?
Indeed, the procedure and capabilities remain consistent throughout the entire hybrid range.
There is nothing remarkable about it, as it merely involves a fundamental drain and fill to drip, rendering a flush impossible. The fundamental guideline is to remove the FILL plug initially!!!!!!!!! They are extremely tightened. Possess a genuine 10mm hex socket that fits perfectly. Ensure it is fully inserted. You might require a cheat pipe as they are exceedingly torqued. Ensure you select the appropriate plug, as there are approximately four or five similar-looking plugs present. The front's capacity was previously approximately 4.2 quarts. Utilise Toyota WS ATF; however, it is inconsequential as it serves merely as a fundamental splash lubricant.
You require either a car lift or four stands, as the vehicle must be level.
Upon making my modifications, I utilised a narrow-tipped funnel, affixed an appropriately sized tube to it, extending sufficiently to reach the fill aperture, and secured it to the hood strut. Alternatively, you will require either a manual or electric pump to introduce ATF.
Once more, it is devoid of any uniqueness. If the fill plug is stripped, you will need to chisel it to gain access.

I appreciate your assistance. In response to your inquiry The reason is that I am approaching 70,000 miles, so I would prefer to address it promptly.

Which powertrain option? The 2.5?

If it is the 2.5, then the drainage and replenishment process resembles that of the Camry, Rav4, Highlander, and Venza, which share a comparable powertrain. Thus, you possess an abundance of YouTube videos to view. Remember to consider the rear differential.

Indeed, it is the 2.5-liter variant. I understand that fluid checks require reaching a specific temperature beforehand; does this also pertain to this situation, or is it acceptable to perform it after the fluid has been stationary for some time, akin to an oil change? I also discovered information regarding the rear differential, and it appears that the total capacity will be 5.6 quarts.
