Q: For the Taurus 8AT transmission, is it necessary to use a circulation machine to change the transmission oil? Is it required to remove the oil pan for cleaning?

You can't use a fluid exchange machine for this transmission because you can't remove the oil pan or replace the filter. Using a fluid exchange machine can cause sludge to clog the filter, leading to poor transmission oil circulation and insufficient pressure in the torque converter.

Don't change it, changing it might actually affect the transmission.

I've driven 46,000 kilometers in over three years, and I'm unsure whether to change the transmission oil. Should I do it or not?

Has anyone followed the manual's recommendation of not changing the transmission oil for 240,000 km and driven over 200,000 km? [I want to be quiet]

The 4S shop said to use a recycling machine for replacement.

It's not possible to remove the oil pan. You can choose between circulation or gravity. Generally, gravity is recommended, but shops might suggest using a circulation machine to make more money.

I got it replaced at the 4S dealership with a circulation machine.
