Tremec Problem

[sixtnine]

I have a 69 Camaro with a 406 and Tremec 5 speed with a UPR shifter. I went to bang 3rd gear and missed. When I did I noticed my shifter hung up about halfway in. I had to muscle it to get it back to neutral. It felt as if the shifter was going into a gate between 3rd and 5th gear. Now it wont go into 3rd unless I ease it in. I spoke to a tech person at Tremec and he thinks the internal rail mechanism has some strained parts. He is sending me some parts for free to fix the problem. Has anyone ever had this happen? Any input would be great. Thanks
