Rear derailleur will not stay in new gear. keeps defaulting back to smallest sprocket. I've lubed everything in sight. I've recently had the cable disconnected from the derailleur, lubed it, then crimped it back down. When I shift, the derailleur moves, but does not ''stick'' in the new gear

What kind of gear switcher do you have?
It sounds like the problem might be there...
That should be the part that keeps your chain in the proper gear..
Does the Switch stay in place or does it go back?
if it does....
Is the cable properly tightened to the raer derailleur?
If so is the cable crimped to loose so that there is to much **** in the cable?
The two screws on teh derialleur itself are only to adjust the maximum outer position and the maximum inner position.
The 400LX is from the Shimano Deore line i think...
From what i here you need a new control switch to keep the gear in place.
I gather this from the fact that you say when you shift up if goes, but does not stay in place and whn you then want to switch down it does not do anything (the switch)
I dont think that you can repair the switch itself,
and from what i read you have done everything in the correct way.
sorry about the typo's just noticed them and i can't find a edit button.
