"DIY" shift kit with 2 new GM 2-3 springs is going in my '97 next fluid change (soon). Why not? Go to the dealer and order springs, go to ace hardware and pick up the rest. Profit. Transgo all the way, but too involved for my DD that needs other things... Installed a Transgo valve body kit in my old K1500 and I love it. The stock 100k mile trans shifts great! Better than the 30k mile rebuild that I smoked last year...
