    1995 Ram 1500 V8 5.2L auto with overdrive, 2 wheel drive, SLT, 160,000
    miles with trailer towing package. Codes 12, 37, 32, 55. 12 battery
    disconnected, 32 EGR and 55 end.

    refers to 3 items,


    1:Shift indicator light failure, 5-speed I GOT AUTO TRANS
    2:part throttle lock/unlock solenoid driver circuit (87-89)

    WRONG YEAR

    3:solenoid coil circuit (85-89 Turbo I-IV)
    WRONG YEAR & truck is NON-TURBO


    4: Trans temperature sensor voltage low (1995 and on;

    see NOTE 2) Note 2 From the 1995 TRUCK manuals: the trailer towing
    package includes a transmission coolant temp sensor while the standard
    package doesn't. This may cause the low (no) voltage indication.


    I Checked around the transmission and found a 2 prong connector coming
    out of the wiring harness and its not connected to anything. I can't
    find anything to plug that into on the transmission. There are three
    other cables connecting to the transmission, all on the same side, one
    in the front by the shifting levers(3 big wires), a small 3 prong
    connector somewhat in the middle and another 3 wire one on the back
    end. Also when I am doing about 55MPH and depress the gas pedal down,
    not enough to kick the gears down, the RPMs pick up about 200RPM and
    the speed starts to creep up. The truck drives just fine.
    Advance Auto had a sensor with two pins but I can't find it on the
    transmission.


    Questions: Where is the temperature sensor for the transmission
    coolant. What is that dangling 2 prong connector for?


    Help PLEASE.

    I installed a new EGR valve. Ran the truck for 15 minutes on the
    highway, no engine lite. YEA!!!
    Why this would make code 37 go away is anyones guess.
