shifting question

Had a ait leak in 13 speed pete in knob itself. Mechanic put on used knob and I think its a 15 speed. What can I change as far as the air lines in the knob to make high side on low side of switch and low on high side of.switch to get my top yop 4 to split up and down. Can shift up but going up hills I cant go to high when I come out of 12th I have to go to 10th.

 

Haul lots of sterl just dont want yo lug so hard and lose so much speed.

 

Lol

 

Any advice.

 

Get the right knob. Other wise you will end up with a back box full of unmated pieces. They have a factory lock out for a reason

 

Wow I would of turned around and took it right back to the shop.

 

Gotta run. Can still drive it just have to lug it to 1300 before going from 12 to 10, 10 to 8, 8 to 6

 

What color is the splitter? 13 is red, 15 is blue. I would think everything would work the same, but if it doesn't work right tell them to get the right one.

 

The first one was red 13 speed. This one is blue 15 speed. But 13 high sides split. 15 low sides split.
