Auto shifter disassembly

You have to push the bottom surround down. Exposing 2 screws. Pull the side plastic that surround the buttons. And its easier to cut the od button wiring as i tried to disassemble one once and it exploded with springs flying out and such. Cut and resolder.

Remove the panel surround.

 

Unplug the blue connector the OD button is built into this fwd of the shifter

 

Pull down the collar. 2 grub screws

 

Remove the OD button with a flat screwdriver. VERY CAREFULLY.

 

The only way to remove the OD wiring is through cutting it IMO, it will save you lots of headache. Stagger the cuts so you can identify which is which (they are just both plain white cables)

 

Fit your new nob, or gear surround, solder the OD button cabling and refit back together.

 

It's a pain of job.

Pretty sure there's 4 wires for the overdrive button, 2 for the switch, and 2 for the bulb inside.

100% only 2 or was on mine.

 

Weird. I've had a dismantled J-Spec one in my desk at home for months, and it definitely has 4 wires. 2 for the button, and 2 for the bulb. White wires are for the button, green are for the bulb.
