4l60 to 4l80
#1
hey guys im getting ready to do my swap in a week or 2 i was just making sure i had everything i need, i got the tranny, already has the shaft mod installed, got a new TQ converter, pcm pins, and ned pigtail for the speed sensor. ill be getting a retune and fluids soon. now i know ill have to cut and weld the crossmember and send my drive shaft off. i was also wondering about the trans lines, do i need to upgrade them or will my 4l60 ones fit/work? i noticed that in the swap the guy did alittle cutting to make sure the headers would clear. the passengers side looks good do i need to worry bout the drivers? ill keep posting in here if i got any more questions. thanks for the help guys
