Silencing and slowing a Bachmann 44 ton switcher

[CAB_IV]

I have a 44 tonner i just installed DCC in. while it was never quiet ( and i haven't used it or most of my other trains in a while because of the switch to DCC) it seems much louder than before.  I know i was servicing a bunch of my locomotives, and the 44 tonner did have big glob of lubricant from the factory jammed in there (literally), and i cleaned it out.  Its still loud.

Whats more though, is that it doesn't creep like i'd like it to.  at speed step 1 its still moving kinda fast. 

What can i do to improove performance?
