Full rebuild video. Driving with this rebuilt part daily. Works better than before! This is also a follow up to a previous rebuild video where 45ml 100k fluid was used. It began to wear down after 50,707 miles. Deleting old videos so that this better video is found.

Symptoms: binding/pulses of resistance/thuds during turns at low speed only. And only when transmission is hot. Symptoms do not present themselves with a cold/cool transmission.
