SRAM S7 Clickbox - whats inside?

I have a good new bike, aprx 18 months old. The gears suddenly stuck. Dismantled the shifter assembly and took it to the shop. A guy who said he was a mechanic claimed the Clickbox was shot. I find this hard to believe, as the bike is barely used.

I took the parts home to work on myself. The shifter on the handlebar opened easily, all parts are apart; shifter, wire and clickbox. But I cannot get the Clickbox apart.

Does anyone know - can the clickbox can be opened and serviced?

Best,
Jan

Thanks but still unclear

Thanks for help!
A lot of good mechanic tips in the TM, but I didn't see any info on actually taking the Clickbox apart.
They say there is a spring inside, which I know.
Best,
Jan

I have an older Sachs 7 with that clickbox, and I am afraid of it. My plan, for now, is to try to find a backup one from Ebay (or somewhere) to cover me when it goes belly up. Good luck, and please do let us know how your repair attempt goes. I will be interested.

Before you go tearing into the clickbox, there are some other possible sources of your problem you should rule out first. Ensure the locating sleeve is firmly snapped in place. That's the red plastic do-dad that the clicbox fits over. make sure the tab is in the alignment notch of the outer shift rod sleeve. Also, with the ckickbox off, push in on the shift rod. Both the rod and the outer sleeve should offer significant resistance and should both spring back out when released.
Of course, the alignment marks in the little window need to line up in 4th position, assuming you have the mini clickbox, which I belive all the newer ones do.
Internal malfunction of the clickbox is unlikely, but possible.
