Code 1762 - tranny guys!!!
popped a 1762 today, truck felt really wierd getting off the line.. felt like i had a higher stall converter in it.. took some RPMs to get it moving..
P1762(M) Gov Press Sen Offset Volts Too Lo or High
The Governor Pressure Sensor input is greater than a
calibration limit or is less than a calibration limit for 3
consecutive park/neutral calibrations.
straight out of the PDF manual..
you guys got any ideas? this has happend before .. at the carwash that has an underbody spray bar.. rolled over that a few times as was doing the same thing.. cleared the codes and ran perfect..id like to nip this in the bud.... assuming a connection or sensor had gotten wet.. reason why im looking at a moisture problem is b/c its been raining alot out past few days....

Got this off the DodgeDakotas.com

There is a whole list of testing procedures but you need a DRBII scan tool to do the tests. If you want the testing procedures anyway, just email me ecallenIL@hotmail.com
SYMPTOM
P1762-GOVERNOR PRESSURE SENSOR OFFSET VOLTS TOO LOW OR HIGH
WHEN MONITORED
Continuously with the key ON and the engine running.
SET CONDITION
This code will set if the governor pressure is out of range in park or neutral for 1.3 seconds for three consecutive bad 3.0 second tests and sump temperature > 10 °C (50 °F) and <
127 °C (260 °F) are required to set the code.
POSSIBLE CAUSES
Powertrain control module
Powertrain control module - 5 volt supply high
Powertrain control module - after 5 volt supply shorted to voltage
Powertrain control module - after 5 volt supply shorted to voltage in trans
Repair the 5 volt supply circuit and check the PCM
Replace the trans solenoid assembly and check the PCM
Intermittent condition
Powertrain control module - internal fault
5 volt supply circuit open
Check for other trans DTC's
Governor pressure sensor signal circuit shorted to voltage inside trans
Check trans fluid level and condition
Governor pressure sensor signal circuit shorted to voltage
Park neutral DTC present
5 volt supply circuit shorted to ground
Governor pressure sensor signal circuit shorted to 5 volt supply circuit
Governor pressure sensor signal circuit shorted to 5 volt supply circuit inside trans
Governor pressure sensor signal circuit shorted to ground
5 volt supply circuit shorted to sensor ground
Governor pressure sensor signal circuit open inside trans
Governor pressure sensor signal circuit shorted to sensor ground
GOV pressure sensor signal circuit open
Governor pressure solenoid
Governor pressure sensor signal circuit shorted to ground inside trans
Powertrain control module - 5 volt supply circuit low
Sensor ground circuit open
Transmission line pressure low
Governor pressure sensor signal circuit shorted to sensor ground inside trans
5 volt supply circuit open inside trans
5 volt supply circuit shorted to ground inside trans
5 volt supply circuit shorted to sensor ground inside trans
Sensor ground circuit open inside trans

That means you go to your local Dodge dealer, grab the Governor Pressure Solenoid, Transducer, 2 gallons of Mopar ATF, a filter, and gasket and change them out. It takes about 1 hour total to do the job in your driveway.
Youmight not want to go the dealer route and pay big bucks for the Governor Pressure sensor and Governor Pressure solenoid. With a little online searching I found Transtar Industries, Inc. at www.transtarindustries.com Part numbers where 20A-120A for the sensor and 5A-303 for the solenoid. The prices quoted me were just over $120 for both parts. This was $100s better than what the dealer quoted me. This was for a 1997 46RE transmission.

RE: Code 1762 - tranny guys!!!
I'd run the wires (all of them) that connect from the tranny to the PCM. Look for worn spots, cracks in the insulation ... I suspect you've got a sensor grounding out somewhere ... especially after reading all of the above ... a lot of stuff about 5V grounding or low.

RE: Code 1762 - tranny guys!!!
I had a similar problem with mine after i took it through a pond. Mine wouldn't shift outta 2nd though. I let it sit for about a week thinking i ripped the tranny out and it was fine when i got back in it. I would like to find a way to better insulate the wires.
