Question about Cycling
Trying to fix the module on the grip-shift is always a waste of time. The best thing to do is replace the shifter.
The shifter pulls the cable tight toward the shifter and uses a rachet mechanism to insure the chain is always in alignment under one gear and does not fall between two gears (like the original multi-sproket bikes from the 1970''s and 80s).
The derailer near the sproket has a spring to pull the cable back for the smaller diameter gears when the shifter is turned the other way.
The light-weight pastic gears and rachet mechanism in the twist grip tend to strip and fail. The small plastic gears are not available as replacement parts except for the highest end shifters (trigger shifters). The twist shifters are considered low-end to mid-range and replacement parts were never available that I remember.
To replace the twist grip, make notes how the cable routes to the corresponding derailer. Detach the cable near the derailer and pull it through to the shifter. Remove the shifter from the handgrip. Pullt he cable through. Pull the cable though the new shifter and mount it onto the handgrip. Route the cable through the rest of the frame as needed (see notes you made earlier). Adjust the cable to just tight enough to keep the derailer above the sproket indicated on the shifter. You may need a pair of locking pliers to hold the cable tight before locking downt the nut on the derailer. There is a fine adjustment screw on the derailer to make final adjustments if needed (they usually are).
Shifters are available at most bicylce stores. You can also find many fairly new bikes on craiglist that you can strip for parts (as little as $25 for the bike). Sometimes they are given away for free on craigslist and you may find an exact replacment - we did!).
Shifters from the bike shops cost $20 to $50 for a Huffy (depending on the bike store).
Good luck, I hope I understood what you wanted from your question.

Most bikes are just static frames with a bunch of aftermarket stuff hung on them.
Everything on a common bike is found on just about any other brand of bike and the individual components are usually documented at the manufacturers' websites.
Places like http://www.parktool.com/blog/repair-help document many of the repair and adjustment procedures.
Google will find tons of How-to videos.
If it's Shimano try http://techdocs.shimano.com/techdocs/index.jsp
