I was thinking of buying this kit for $139.00:
After reading the ease of installation from another site but while I was putting in my due diligence in the process, I found one person who stated the following:
I just had my friendly Toyota mechanic install the URD Short Shifter kit in my 6 speed manual 05 Tacoma. It took 0.7 hours or 32 minutes (first one he had done).
Reverse was difficult to shift into at first but it seems to be getting easier as I use it, or I am getting better at it.
One issue: the clearance between the steel transmission tunnel of the truck floor and the bolt in the bottom right corner of the kit was insufficient when the transmission was under heavy load (happened in first and second gears mainly) resulting in a horrible steel rubbing steel grinding sound at times. However it did not take long to figure the problem out. The solution was to bend the transmission tunnel steel up a bout 1/8" to provide more clearance.
After that bug was worked out, I am happy with it as there is a noticeable improvement in the shifts and the shift throws are about half of what they were.
