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.
