Transmission Paddle Shifter Issue - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

DP Valentino · 11-10-2014, 10:59 AM

I just recently dropped my car off at a local Chevy dealership where I live, and described my problem to them about how when I put my transmission into Sport Mode. That my paddle shifters won't switch between sport, M1, and M2. As soon as I said that. The dealership quickly said it could be my Hurst Automatic Shifter(Stick and plate) I installed. I still have the steering wheel paddle shifters factory, and have not modified them. The steering wheel paddle shifters just stopped working a couple of weeks ago. I had my Automatic Hurst Shifter Kit installed 6 months prior to this issue. So my question is can that cause problems with my steering wheel paddle shifters? Keep in mind I can shift to Sport Mode fine. It's using the paddle shifters afterwards that is the problem.

If you can shift into sport mode but the tapshift feature won't work I don't think it's the shifter.

The Hurst Comp Plate and Stick kit that you have installed on your car has absolutely nothing to do with the operation of your paddle shifters. Our kit is an aesthetic piece, not an actual "shifter". All that you have changed is your shifter handle and the surrounding bezel.

That what I explained to the dealership. Thanks for the additional input!

The shifter handle plays no role in tapshift ( with the exception of my shifters), the shifter itself plays a limited role by mechanically moving the linkage to the transmission.All electronic functions are in the transmission itself(TCM) wiring and tapshift switches.

Quick question, will the tapshift buttons do anything, such as shift down once or up once or do they do nothing?

The tapshift did nothing once I pressed them. I figured it have to be a electrical connection. I also told the dealership this issue, but they seemed so focused on my shifter handle. I think they are trying to use that as an excuse to whesel out on doing warranty work.

I had a new steering wheel put on and for some reason the electrical connections were not hooked up, which gave the same error as you described. If that is not the case then the modules themselves are bad. Either way the dealer must start troubleshooting at the steering wheel.

Good luck, and if need go to a different dealer.

The dealership just called me and told me they were getting back feed from my audio amplifier I had installed in my car. In order for them to continue to diagnose my problem. I would need to go to the audio shop I had install the audio amplifier and have everything disconnected. Then have the dealership continue with the diagnostic. The tapshift worked even when I had my amplifier installed! I may have to have a professional electrical car shop do a better diagnostic! Ugh!!!

Typically, it's not difficult to determine if the problem is the switches, wiring or TCM. If in fact the audio system is causing the issue it should be easy enough to determine. Are there any codes stored?

DP Valentino · 11-10-2014, 06:03 PM

I will ask the dealership if there was codes thrown when conducting the diagnostic.

CFD · 11-10-2014, 06:17 PM

There are several codes for downshift/upshift switch circuit errors that may show. I'm not sure how the audio equipment would affect tapshift. The tapshift switches work by varying resistances not voltage.

What tool is used to read the transmission codes. I have an OBD2 Diagnostic Tool. Is done by plugging up to panel underneath the steering wheel column?

I think that will read them. I believe they are PO815, PO816 and PO826

You need a tech tool for BCM, TCU codes or a program like solus. The ECU codes can be read with a basic code reader. This is from my experience of having 4 BCMs replaced and trust me dealership did the same thing blamed everything including my supercharger that had nothing to do with it took it to a good electrical shop and they fixed all the shorts
