Manual transmission still making noise after fluid top off
Topping off the transmission fluid can quiet most gears, but a specific gear like 6th can continue to wear down and grow noisier if internal components are already damaged. This persistent wear leads to total gear failure, effectively turning a multi-speed transmission into a lower-speed unit.

“It was making a noisy whirring sound for a last couple weeks. We topped it off with ford DCT fluid and the rest of the gears quieted down but 6th seems to be getting noisier. Is the trans hosed?”source ↗
