Adding Paddleshifters

[BORN2SKI]

This pic got some ppl thinking, is it possible to basically hack the trans and add paddle shifters?


Here is a wiring diagram for the 4t45e (Is this what we have?)...


I was thinking that you could somehow tap into the tap up/down switch signal and send a signal that the manual shifter is being pushed, even though it isnt.
Does anyone have a pic of the shifter with the centre console removed?

And feel free to post ideas, maybe someone could actually give this a try! That would make one unique G6!

Re: Adding Paddleshifters

it certainly appears that it would be a relatively easy conversion...

but we would need to see a wiring diagram from the car the wheel with the paddle shifters came from to determine how they are wired and interact with the PCM...

Re: Adding Paddleshifters

im pretty sure it would work, all you would have to do is extend 3 wires from the shifter assembly where the contact points are, and if you just put them in paralel you could use either the paddles or the tap shifter..............BUT im pretty sure you would need an 09.5 wheel with the switches with the paddles on them, as the 09.5 modules dont fit in the 09 and old wheels if i remember correctly.......this is gonna be a project i have for my GT whenever i have some extra $$ laying around, and if i like it im gonna add it to my GXP............

on a bit of a side note.........does anyone know if i can put the 09.5 climate controls in my GXP? its is already automatic controls and i see no reason why it would comunicate with the BCM in any way.........any buddy know for sure?

sometime in the futere im also gonna try to pick up an 09.5 cluster and wireing harnesses /wheel and see if i can get it to work by cutting and spliceing some wires lol but thats gonna be a project for the GT haha at least for the test anyways........dont wanna go cutting up harnesses on my new GXP just yet unless i know its something that will work haha........

Re: Adding Paddleshifters

Did some thinking and talked to someone at the place that does the electronics installs in Toronto for GM. They said that the steering wheel audio controls are all resistance based, and to change the function of an audio button would require changing the resistor. I think that the paddle shifters would be the same, also see picture...

I have a limited electronics background, but from how I read this, you would need to add a circuit in parallel to the existing tapshift circuit (see pic). This new circuit would need to have the listed resistors, and would require the trans to be in manual mode.
It seems that the resistors for manual shift more are only active while the trans is pushed to up/down shift.
I think that the easiest way to to this us to use a momentary switch to initially test, then eventually find a wheel with actual controls.



If there is anyone with an electronics background (*COUGH* Calvin *COUGH*) that could chime in on this, please do so.

Re: Adding Paddleshifters

I somewhat doubt your current wiring harness has the necessary wires, so you'll probably need to start there. See if you can find a steering wheel on eBay that has the TAPshift switch. 09.5s officially have steering TAPshift.

That's how I'd approach it.

Re: Adding Paddleshifters

I was thinking more along the lines of adding a completly new circuit that goes from the trans to the steering wheel and back, not using the existing wiring harness

Re: Adding Paddleshifters

I am not extremely electronic competent, but from what I see... I don't see how this wouldn't work!! You are correct that the shifter needs to be in the tapshift mode to enable this (pretty sure)... But I don't see how you couldn't just wire the right paddle into the upshift and the left paddle into the downshift...

I am by no means an expert tho so I could be way off!! But I was thinking something like this:

Re: Adding Paddleshifters

The reason for adding a second circuit is to maintain the existing tapshift

But the way I did it it would too wouldn't it?? (Realize that I don't really know anything about this) But if you just wired it directly into the wires behind the up and down shift... wouldn't the computer see you pushing the paddle and pushing the shifter as the same exact thing?? Thereby giving you the option for both??

Edit: I do see what you mean too... Because that would totally work too (as far as I know), but wouldn't mine be a short cut?? If not, I will let the big dogs talk this out!!

Basically putting a switch in series with the tapshift controls?
If so, that would not work because you would have to push both the tapshift, and paddleshifter at the same time for it work thereby completing the circuit.

hence why i chimed in LOL, i took colleged electrical/electronics engineering classes the last 3 years of HS and have been playin round with electrical/electronics since i was like 5............built an entire control system that uses the computer to run my backyard powerline and built my own amp in HS for my sub lol...........

honestly i will be willing to bet that the resistors are already in the switches from 09.5 only thing you have to remember is those switches wont fit in the older wheels so youd have to get the whole 09.5 wheel.......

i definately want to do this but i got some mods id rather do to the GXP first so whenever i get some extra $$ i can be the gunea pig if no one else has tried it yet lol...........

I know it would be crude, but what about improvising something using just a basic momentary switch recessed into the '06 (or w/e year you have) steering wheel?

Oh ok... that makes sense I guess!!

SexyG6: I wasn't going against what you were saying... I realize I am not the electronic guru you are; I just thought maybe I was thinking simpler then you!! But I think I would replace the whole steering wheel anyway because I wouldn't wanna try modifying my current one and BOOM the airbags go off!!

Re: Adding Paddleshifters

also, not 100% sure on this but i dont think its like matt has is as far as the left and right as in all the pics ive seen they have a plus on both sides so im thinking that you push either on of the forward to go up and pull back to go down but i havent driven a 6er with tapshift so i dont know, and yes it would have to be in paralell not in series and according to the diagram you should only have to run 2 wires, it looks as if the resistors are internal to the switch, and that the switch thus only has 2 conections...........
