the lucas honey by itself cannot pass through the filter on these transmissions, it needs to be mixed up thoroughly before pouring it in. (I bet the trans pump is noisy too at this time)

removing the sump and changing the filter then filling new ATF can most certainly bring it back to whatever condition it was in previously.
