It's probably fine fine for your personal campaign but it wouldn't work for most DMs. A 13 HD dragon w/Str 17 would be similar to a Juvenile White Dragon (12 HD and Str 17).

It's missing feats. There's no Str bonus to attacks? Which attack is primary?

4 telekinetic slams + 13 ranged (2d6) belongs in the stat block somewhere. Note: your creature has Int 10 not 12 and so gets no bonus from Int.

Special Abilities have a designator: Ex, Sp or Su.

Telekinetic Slam (Su): In place of a breath weapon, this dragon can take a standard action to perform four telekinetic attacks with a range of 30 feet. These attacks have an attack bonus of BAB + Intelligence modifier and are not touch attacks. They deal 2d6+Intelligence modifier damage each. These attacks can be used to perform combat maneuvers such as bullrushes, sunders, trips, and disarms. When doing so, the dragon loses any size modifier it may have and uses Int in place of Str or Dex for any stat check. After using this ability, the dragon must wait 1d4 rounds before using this ability again.

Generally with special abilities, there is a save to avoid the damage or to halve. If there is no save, you should state this.
