StageaNM35 triptronic gear stuck 2002 model Stagea When moving from automatic to the triptronic gears , the gear remains in 4th . It will not move up from fourth gear nor move down to other gears. This seems to happen on a highway trip of about an hour or more. If I turn off the engine and re start the engine the problem seems to disappear. Any possible idea as to what is happening?

Hello everyone, BEFORE I START PLEASE ASK QUESTIONS IF YOU HAVE THEM For a few months now I have been thinking about changing the controls on my old Triptronic steering wheel to audio controls and this weekend I actually sat down and did it. I must say that it was quite the bitch, and I went through many different designs before I had the final version, and this final version, in my opinion, is the best way of doing it. This guide isn't a step-by-step walkthrough unfortunately because I have already installed the system into the car, I am writing this in retrospection so other people can also do this on their cars, as I have seen it asked about many times. First I'm going to cover other designs that I have seen which are either stupid, needlessly complex or just wont work as expected FAILED DESIGNS Using a 4-way transmitter and reciever (As seen in THIS video) (Would work but needlessly complex and many POF) Wiring resistors inline and running wire from steering wheel back to head unit (A steering wheel rotates //2short) Using a pre-existing PCB and wiring it in on the "dash-side" of the steering column (Ribbon cable in wheel boss wouldn't support enough inputs) OK, Now that that is out of the way. We get onto the good stuff. Below is 3 things. REFER TO THESE INCASE OF UNSURE OR COMMENT 1. A video of the finished product AND a talkthrough of how it is all wired (I rambled a bit) 2. A rough wiring diagram for reference 3. The notes of which wires are connected to what and the pin layout of the PCB. ALL WIRES MAY NOT BE 100% REPRESENTATIVE OF YOUR CAR (ie. Different Colour or Pin) SO PLEASE CHECK WITH A CONTINUITY TESTER FIRST WHAT YOU NEED Steering Wheel Control Harness (Most often comes with your stereo as a 3.5mm jack) Universal Wired Steering Wheel Controller (What I used) (I MIGHT SELL PEOPLE JUST PCB's WITH THE WIRES PRE SOLDERED ECT IF YOU WANT ONE PM ME) Soldering gear and experience Plenty of wire OPTIONAL: Desolderer (Expensive and doesnt need to be used but makes light work of desoldering PCB) HOW YOU DO IT ALL WIRE COLOURS THAT ARE UNDERLINED ARE THE STOCK WIRES, ALL IN ITALICS ARE THE WIRES I ADDED PLEASE TEST THE CONTROLLER AND 3.5MM JACK IN YOUR HEADUNIT BEFORE INSTALLING ALL COLOURS AND PINS MIGHT BE DIFFERENT IN YOUR CAR SO PLEASE PLEASE PLEASE CHECK BEFORE YOUR CUT ANYTHING Prepare the PCB Take apart your Universal SWC and remove the PCB. It should have a number of tactile switches on it and a power cable Test and notate which pins are Ground and which pins the actuation pin is. (This can be done with a continuity tester) In my case the whole board shared a common ground between all switches Desolder all of the tactile switches Solder new wires to the actuation pin for each switch Solder a wire to the common ground for the board. You should now have 5 wires soldered to your board (4 actuation + 1 ground), as well as the 2 original power cables IF YOU DONT HAVE THE TOOLS OR SKILL FOR THIS I MIGHT SELL A PRE-SOLDERED PCB FOR THOSE WHO WANT ONE (PM ME IF INTERESTED) DISCONNECT THE BATTERY!! Remove the Airbag Remove your key surround, upper column cover and lower column cover to gain access to the steering column (5 Phillips head screws in Lower cover) On either side of the steering wheel there is a plastic cover which covers a Torx Head Screw holding in the airbag. Remove both covers and screws Disconnect both plugs on either side of the steering wheel behind the previously removed covers. The airbag should be able to be pulled out now Prepare the Switches With the airbag removed you should be able to see the wires for the switch relay. Find where the two switches combine into a single output in the centre of the steering wheel and cut just before here, so that the switch wires are seperated. Solder the "COMMON GROUND" from your PCB to the YELLOW wires from each switch. Solder the "UP" from your PCB to the GREEN wire (One Side Only) Solder the "Down" from your PCB to the BLUE wire (Same Side) On the other side, "Next" -> Green // "Back" -> Blue Connect PCB to Loom On the passenger side of the steering wheel there is a plug, make sure it is disconnected. On the upper plug, follow the wires back to the cut you made earlier. Clean up and hijack the BLUE and YELLOW wires. Connect the POSITIVE wire from the output of the PCB to the BLUE wire, and the GROUND wire to the YELLOW wire Tap Wheel Harness On the back side of the of steering wheel boss there is a cable with a yellow plug (the wire itself is also probably covered in yellow tape) which runs back into the dash. Locate this plug and strip back whatever is covering Cut the 2 GREEN wires on the PASSENGER SIDE of the plug (Make sure to leave enough wire to solder to) Solder a POSITIVE wire to the INNER wire that you cut (INNER to the centre of the plug) (Make sure its long enough to run to the back of the stereo) Solder a NEGATIVE wire to the OUTER wire that you cut (OUTER to the centre of the plug) Connect Harness to Audio Jack Make sure you have enough wire to reach the back of your stereo Solder the POSITIVE wire to the "INPUT1" wire on the SWC audio jack Solder the NEGATIVE wire to the "GROUND" wire on the SWC audio jack Plug controller jack into Reconnect battery and test if working If working DISCONNECT BATTERY!!! Cable manage and protect your PCB with whatever you can (I used heatshrink) Reassemble airbag (remember to reconnect plugs and TORX screws) Reassemble steering column If not working Check your wiring against mine in the diagrams and the handwritten sheet (The handwritten sheet is the notes I took on the day so they are 100% correct for my install) Use a continuity tester and check wiring if able Write a comment and hopefully I will be able to help ENJOY THE AUDIO CONTROLS Conclusion If you need help with anything dont be afraid to comment and I'll help out the best I can. I have seen tons of people asking about how to do this for a number of years now but I believe this is the first tutorial. I posted a couple videos to facebook of it and there seems to be alot of people who are interested, however, I believe that people think its a lot less time-consuming of a job than it actually is.
