I have the TWM short shifter. From what I've heard it's better than the TRD. I installed the TWM a few weeks after I purchased my GT and don't remember noticing quite an improvement. The stock shifter is squishy due to the plastic shifter frame and rubber bushings. I mounted the TWM steel frame to the steel on the dash/chassis and it's a little rough, would like soem thin poly bushings to get rid of the harshness.
