Can Auto tranny harness work with 5 speed

[skeeterone2]

I have a 92' lumina 3.1MPFI and i am going to change it from auto to manual and i was trying to figure out if i had to change the harness to a manual harness or keep it as the auto harness... i was thinking all that would have to change is the chip... am i right on thinking this? and if i do have to change the harness WHY?

You wouldn't have to change the harness or the chip.. With the 3.1L you'll have a 440t4 auto transmission in your car.. it's not computer controled so you wont have to worry about any of that.. when you do how ever changed over to a 5 speed you'll have to do something about by passing the nutural saftey switch and wiring in clutch saftey switch and also reverse lights switch..

You should swap to the 5 speed chip so the IAC is programmed better for the manual, along with the fuel and spark changes made, especially decel. You dont need the clutch switch as long as you know to start the car in neutral or with the clutch pressed in. Reverse lights, I gotta do that still on mine. There are only 4-5 wires you need to deal with, pocket-rocket or oldskoolgp should know which ones they are.

Yeah, we figured out a couple of other things with the harness that I haven't told Jon about yet. I'll probably do a write-up about what needs to be switched.

Cool, let me know...or just submit it as news and ill post it up.

Does it have anything to do with my code 56...cause I cant remove what doesnt exist...yet pops up anyway.

[skeeterone2]

that write up would be nice. thank you for your help.

[OldSkoolGP]

It's 80% done now. I have to go back and confirm with my buddy some things to be totally accurate. I'll try to have it to Ben today.

awsome yeah i forgot about the ignition wiring and the backup lights..... i was thinking too much on the mechanical end of things.. and that damn steering column. that would be a great help.... is changing the steering column a big deal? with the ignition an all?

[skeeterone2]

Hows that write up coming Old skool?
