Speedo gear fell into transmission HELP

[brad4176455]

So today i decided to pull the speedo gear house out because i thought it was leaking around the seal. So i disconnected the cable loosened the bolt with the clip and proceeded to pull out the housing. I then notice the speedo gear laying in the hole. so i reached up to get it and it fell into the transmission. Stuck my finger in and tried to fish it out put now i cant even feel it. WHAT SHOULD I DO? i did some looking online and saw alot of people have had this happen and said to just leave it in there. What are yor guys suggestions
