System Information
Operating system and graphics card
win 7 ,,i5
Blender Version
Broken: (example: 2.69.7 4b206af, see splash screen)
Worked: (optional)
blender 2.71 d919218
Short description of error
transformation constraint does not work correctly when at certain axes
Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps
open untitled.blend just follow inside .blend file..steps were given.i guess this is bug

Checked the file, followed steps and can't see any problems.

I couldn't get it to speed of the track rotation to change.

The track is moving when Bone's X axis location.

Need more details on what exactly isn't working.

the speed of track in certain direction,.from the file.blend, the x axis does not rotate constantly compare to the speed of track in other directions.

first from top view u just move in x axis in local coordinate system(which is in global y coordinate system ) back and forth,u will notice no motion of track if it can just really slow.
but if u rotate any directions and move the object from top view(just play around from top view as given.),the speed of track constantly rotates.
here what i really confused.
why in global y direction the track does not move or slow in motion.but other directions it works perfectly.

You are just misunderstanding what local space is. For a root bone, it’s the same thing as Pose space, i.e. the armature object space. Which X axis is aligned with world X axis. Everything works as expected, no bug here. Thanks for the report anyway.

complete_tank_bug_transformation.blend this file from cg cookie ,which mean made by tutor from cg cookie,and still not working,the track sometimes goes crazy when rotate ant certain position,the constraint used is transformation constraint ...COULD YOU MAKE TANK TRACK WITH TRANSFORMATION CONSTRAINT ...PERHAPS YOU CAN CORRECT ME WITH TRANSFORMATION CONSTRAINT THAT U MAKE.. FOR NOW I DONT HAVE IDEA TO MAKE IT MOVE SMOOTHLY AND WITHOUT ANY FLIPS
