The second kit "26-4L60E-E" is for a 4L60E converted back to a 700R4 transmission kit and the shift's as controlled by vacuum like the old school turbo 350 transmission.

The first kit you have posted puts you in command on to your shift points up or down but ill have PCM conflicts to the 98's and newer vehicles. I personally stay away from shift kits unless internal parts have been replaced.

For the 4L60E transmission, there are simple thing you can do like replace the;

1. Boost valve to 0.500"
2. Replace the servo's with Corvette servo's
3. Removing the checkball from its cage in the case in the rear of the trans should help shift to be faster fro 3-4.

Start with this few things that should keep your transmission running 100% and the shift points can be reprogrammed by a tech2 scanner or any HP tuner.

Good luck and keep us posted.

The Corvette servo's have a larger are then the stock servo's so they have more pressure on the bands giving the transmission a much more firmer shifts. The Servo's can be replaced in about 30-45 min without dropping the transmission and it's located on the passenger side of the transmission.

Here is a link on hot to replace the servo's and the cost is under $45.00 and can also be found for around $25.00 on e-bay.
