Thread: Adding Performance Shift [*]

This HOW TO write-up on Adding Performance Shift has been added to the How To Section and can be found HERE

I posted this on the KC and STL Boards, but I figured I would post it here as well.

Its just the installation portion of the PS wiring to the PCM. Everyone varies on how they setup their switch for the PS option. Whether it be the Shifter Button or a flip switch located somewhere else. This is the part is the trickiest for most people.

I hope you all find it useful

GREAT write-up James. I moved this to the How-to section.

LOL I was wondering what happened.

Sorry I did not see this section in the first place.

Thanks for the change sir!

Very nice write up

i have a 2k gtp and i have this option, but has anyone ever noticed the performance shift on the gauge cluster? how can i getthis to light up?

Not 100% sure on this, but I believe that if you have the DIC that has "performance shift" then that is the one that will light up. If you dont have it on the DIC, then the cluster one will light, but you cant have both.

It was about 4 years ago that I read something on that, so I may be wrong, and never checked into it because the DIC lights up fine for me.

1998 is the only year Perf Shift will light up in the Cluster as far as I know, otherwise it will light up in the DIC. You can add the Perf Shift in the cluster too as long as you have the right socket + blub.

I added it to mine so when Perf shift is on my DIC lights up and so does the cluster. I added it because I had a spare blub and socket laying around. Figured what the hell, right? :-)

NOTE: I don't know if this will work on 2001+ that don't have Perf. Shift factory wired up.

I think is mostly correct. My DIC was the one that came with the GTP package so it had the PS indicator there. I never saw it on my dash. I only knew of it on my DIC. And never looked at my dash that closely to see if it was even an option on it. But any of the DICs that had the BOOST feature on it, also had the PS indicator on it as well. They went hand in hand.

so what would i need to do to get that to light up? would the socket and bulb be something i could find locally or would i have to find on to take off another gp? i think it would be cool to have both light up also.

I had a spare cluster so I took the blub and socket out of there. I donno where you can get one honestly. Dealer may sell replacements for your cluster. Either that or go to a junk yard and yank the blub/socket. Several of the idiot lights are the same blub/socket including the oil pressure. Take out your cluster, you'll see exactly what i'm talking about. The socket is opened on the Perf Shift light. Just put a blub/socket in that hole and thats it. It lights up blue, just like your brights light

This statement is true. My PCM was a stock PCM that several people in my local club have helped modify through changes for performance and added the PS in the tranny tables.

First off you do NOT need the performance switch leather knob to enable your performance shift. If you read my write, I said in there you do not need the shift knob to activate it. You need simply a flip switch to activate and deactivate the PS mode. You just need to have the wiring setup for the PCM to switch it on and off. And you can have a grounded flip switch on the dash or center console if you want to do the same thing as the leather shift knob would do.

Its really just a preference to keep my car looking as close to stock as possible inside.
