Thread: ZF 4HP22 Gurus. Advice needed.

I used a water based degreaser then dried and flushed everything with new atf before installing parts. Torque converter was renewed as it was sus...filled with 2 litres atf b 4 installing.

Not sure how you would clean the tc...fill and drain I guess..but they take ages to drain😐

this car sat on a driveway for 3 years. gofer :-)

I use warm soapy water, rinse with hot water, dry it then wipe it in fresh atf.

you cant completely drain the TC so just get what you can out fill it with some more, turn it a few times and repeat.
