Hello, I swapped in a 4L60 tranny into the Carlo and I am having difficulty adjusting the original shifter linkage so that I can use all four forward gears. I am finding there is not enough ajustment available when using the original shifter rods and linkage. I was thinking I should extend the arm length 1-2 inches to allow for more movement. Has anyone encounter this situation and if so did you swap in a different rod and linkage assembly or did you modify the original parts.
Any help would be appreciated
