Check out the following demonstrations and thread on the possible pitfalls of adding additives to your car's lubricants (e.g., engine, tranny, and gear oils).
In short, it is suggested that the addition of "anything" throws off the "balance" of the base lubricant. In this case, while adding Lucas' additives might increase the "crawl/stickiness" it doesn't include additional anti-foam additives, so when the gears get moving, air becomes trapped, you get cavitation, and less lubrication.
