Filtered out those observations with zero density both before and after the gear change, as this will bias the estimates of the gear change effect downward

I also switched back to using the raw gear change estimate (unadjusted by rate of change calculations). I think adding in this extra estimation uncertainty just further confused the estimation issue. Better to go with the slightly conservative but less variable estimates from before.
