Shift kits.. do you really need one????

.............I have been using trans-go kits since the mid 80s and yes I have expiramented with different things and have found what works and what doesn't, but for someone that has limited knowledge I strongly recommend to get someone that knows what he/she is doing.......depending on how u want it to shift u can make it shift nice and firm without cranking up the line pressure without a shift kit....kim.........
