Well, I finally got the TransGo Street/Strip Shift Kit installed, and let me tell you.... Holy F'ing S! What difference, like night and day! There is absolutely no lag between shifts. When it does shift, it does so in the time it takes you to snap your fingers. Shift points are unaffected as well. Downshifts are crisp and clean. I'm totally impressed with what this kit has done for my sloppy automatic. Under normal Grandma type driving situations, the shifts are smooth, maybe 1/4 throttle, but once you accelerate at 1/3 throttle or above, you can feel the car lurch forward (the neck snapping some people comment about). Under WOT, hold on to your keister mister, the car not only lurches forward, but feels like it launches off of each shift! In fact, with my minimally modded engine, I actually broke the tires loose going from 1st to 2nd gear, and that's with the T-Lok too. Yes! Downshifts are clean as well when cruising along and you punch it. The tranny no longer farts around thinking about what gear to go into, it just goes. This kit also allows you to hold 1st thru 3rd to any RPM, which I haven't played with yet, but I'm sure it would be great for the track if you haven't installed anything else in the tranny yet, thereby converting your car over to a stick (almost). This is definitely an awesome upgrade for anyone who's sick and tired of his or her automatic's performance. The only thing is, I did not install it myself, I did not want to deal with the tranny fluid all over the garage, as I'm sure I would have had the stuff all over the place, but from watching the supplied video and tranny shop doing the install, it is straight forward and fairly easy to do. I would recommend going with the firmer 1st to 2nd gear shift option, and not wait for the test drive first to put it in later, as this option makes the tranny shift just like all the other shift points. Just thought I'd let everyone know about this!
