Manual Shift no worky

Roscopcoletrain · April 12, 2018

So shifting to M, the +/- does nothing. I took off the column plastic, orange cable seems fine. Tow Haul button works. Is there a fuse or ??

What do you mean by it does nothing? Does the gear indicator on the dash change?

It does not work like a manual mode where you can upshift and downshift at will. You use the +/- button to set the highest gear you want the transmission to be allowed to go into so it is really a "limiter". After you set that it shifts by itself but will not go higher than that gear (for example if you set it to "M5" it will never go above 5th gear).

The wires normally break inside the handle near the button. Here is how you test it. Disconnect the orange wire and using a voltage meter goto the Ohms setting and touch (don't cramp them into) the terminals on the switch side. Toggle the + and Minus button and you should see the resistance value change higher then lower. If it does not, you have a bad shifter switch.

meaning if I go int M_1 I can't + to M_2 or from M_2 down to M_1

Yes it will do that just be careful about downshifting too soon. But sk is also right, if you set it to m4 it will not shift into 5th or 6th unless the computer thinks it's going to over rev.
