You need the part from Speed.inc . A short harness that elimantes the block to 2nd gear on a up shift. In another section mot250 tells of it and even has a picture showing everything. I ordered it and put on my 6speed R/T yesterday . Now I'm happy . Total cost including shipping is $28.18 . This harness is used on the Corvette also . But same trans as we have and the Viper.
