02 duramax shift problem

[iowatruckpower]

i Have an 02 Duramax edge with attitude , Have used a Bullydog speedometer tool to adjust stock speedo for 315 tires . also did a Bullydog shift kit,springs in the valve body, My 3 to 4 shift is jerky.Is it the edge doing that? Can I run the edge with efi live and defuel ecm to get it to shift right? I havent ordered efi live yet

you dont want to run anything with efi. just get efi and run it by its self. it will allow you to adjust for larger tires. also i would get rid of the bullydog shift kit and get a transgo. not transgo jr. the full kit

I agree, run efi by itself.


Nothing shifts good with edge. get rid of it.
