Which Shift Kit
However if you dont mind tearing the trans down a bit or optionally somepeople only to the valve body/servo mods the Transgo Hd2 would be a good choice.

Or also some people like the superior kit as it does not require trans removal to install the complete kit I dont have a link for it, I have used and installed both. The transgo is a bit more involved. Both seem to get the job done.
With a stock trans I dont suggest exceeding the middle settinsg with holes sizes etc.

Is a shift kit required or recommended?
10. Yank Performance Converters can achieve maximum performance and efficiency without the use of shift kits. Shift kits dramatically raise transmission line pressure to increase shift firmness. Increased shift firmness will not increase performance, but create unnecessary stress on the transmission and other drive-line components.
