I found this shift kit eBay Motors: TRANSGO 4L60E 4L60-E SHIFT KIT GM CHEVY TRANSMISSION (item 4593056937 end time Oct-08-08 21:47:55 PDT) Will it work? Also do I ''NEED'' a shift kit with billet servo's? Or will it run fine without? Also What about this Stall? eBay Motors: 98-up Chevy Trailblazer, 4.2L Rebuilt Torque Converter (item 150218481258 end time Oct-18-08 13:27:09 PDT)
