    Determine Transmission Gear

    Does anyone have any ideas on how to determine what gear you are in, mind you this is on an older car, a 94 Dodge Spirit, its a floor shift Automatic, I was thinking of making a ribbon controller and then using the ADC on a PIC to determine what gear I am in, but does anyone have any better ideas?

    with an automatic?
    first: why?
    second: you would have to hack the valve body. I'm very mechanically inclined, and I hesitate to mess with valve bodies, unless I have another car to drive. You probably WON'T get it right the first time when putting it back together.

    wrong, wrong, wrong

    REAL simple

    GPS speed / RPM -> program a range


    in other words, if you're doing 70mph and the engine is spinning 2500RPM, you're in 5th gear,

    Maybe I should've worded it differently, I'm going to have a small 4" LCD inbetween the gauges in the dash for Navigation and other Info, and I want to display R, F, N, D, OD and maybe highlight whichever one I am currently in.

    what is "F" ?

    do 4x IR emitter/detector pairs, installed below the shift trim, so that the shift handle blocks a E/D pair, resulting in data

    what is the setup currently, if there is some sort of lighting for this anyways you could likely just mod it

    I meant P not F, i have no idea how I made a typo like that, anyways, the IR E/D sounds like a good idea, but I will check to see if there is any lighting like Anshu suggested, first.

    Thanks for the ideas

    i would think you should be able to use a relay pattern and, and a hacked usb device. when voltage is running through the lamp for P R D..... you could use a relay to close the circuit for a button on a HID game controller

    If it's an electronic tranny, it's likely just a wire with a variable current or resistance coming off the shifter. This is the case on Fords, though I don't know about Mopars.

    Regardless, it should be easy to tap. Those of you thinking about the valve body, you need to think simpler. Position sensing on the shifter is very simple, and as long as he just wants his carPC to display the selected gear and not real-time tranny info, that's all he needs.
