Now that I've actually read your post...
When the 'T' is present, it means that 'x' permission is has not been given on the directory/file. If you give 'x' permission then a 't' will be shown.
You can set the 'T'/'t' with a 4 character permssion, rather than a 3 character. 0777, for example, whould give rwx to owner, group, and world. 1754 would give rwxr-xr-T permission.
The first character controls the SUID, SGID, and Stickbit.
0 = All bits off
1 = Sticky bit on
2 = SGID bit on
4 = SUID bit on
5 = SUID and Sticky bit on
6 = SUID and SGID bit on
7 = All bits on.
