Transgo kit would do everything you need and can be found on ebay cheap
Thrasher isn't much different than the Intense one.

The basics of the shift kit is that it limits the movement in the accumulator. The accumulator slows the push of fluid behind the piston that engages the gear. By limiting movement, the fluid gets there faster and engages the gear.
and isn't this considered a band aid for an aging trans as well, like when it holds a gear too long?
