Many aftermarket shifters concentrate on shifter stops. Pro-5.0's Power Tower goes a step further, offering a straight-line shot that keeps the handle from going from side to side on the way from Second to Third gear during aggressive upshifts. Transmission damage happens most often from missed 2-3 shifts than from overshifting, which is prevented with positive stops. The Pro-5.0 Power Tower saves expensive '83-'95 Mustang T5 and '96-'01 T45 five-speeds from damage caused by bad shifters and miscalculated upshifts.

Danny Walker of Grapevine, Texas, owns a '95 SVT Mustang Cobra with the T5 five-speed transmission. (Although our project vehicle in this case is a Fox-4 Mustang, this shifter will work very well in a vintage Ford fitted with the T5 transmission.) He found out the hard way about misguided shifts, which is why he's opted for a Pro-5.0 Power Tower shifter. He managed to negotiate the rather challenging zigzag path a stock shifter yields from Second to Third gear. But at 6,000 rpm, he shoved his stick too hard into Third and broke off a shifter fork in the stock T5. Shifter stops would have prevented this.

The forks slide the synchronizers back and forth over the gear clusters with the movement of the shifter handle. If the distance is 1 inch, the forks move just that 1 inch. This is the stop you feel when shifting from gear to gear. Using excessive force tends to damage or break the fork. With enough abuse, forks fail.

The Power Tower takes the abuse instead of the forks and synchros. This not only makes the T5 or T45 easier to shift, it also helps them live longer.
