Re: Grand Cherokee laredo P1763 and P1762
It's a transmission related problem, that you should have looked at a.s.a.p. to avoid costly transmission repairs down the road. Have it scanned at a reputable transmission repair place, dealer, or mechanic you trust. The drain pan will have to come off to perform repair, so have a transmission service (filter & fluid) done while your at it, unless it was done recently.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repair professionals here in the US. click here to Talk to a Mechanic (only for users in the US for now) and get all the help you need. Goodluck!

probable. implies asking us to guess? wildly the 7 codes
P1 mean factory code, (so only jeep codes work) the 7 means tranny errors.
please read the page in the FSM that explains each. YJ jeep it is; (usa) click emmision chapter 25 page pdf #15 , see?
The Governor Pressure Sensor input is above an acceptable voltage level. (so in all cases) 1: the sensor is good and not fibbing 2: or is bad. or has bad wiring connections to it. if #1 the transmission needs service, might have bad pressure reg. do the line pressure tests?
does it shift oddly. does it pass the stall test. in the manual.
both those codes are for your transmission governor pressure sensor .and your pressure sensor .to fit them drop the pan in your gearbox .remove your filter chance to change that will it is off. now you can see both your parts.pull off the plug from your governor pressure sensor and replace.now pull off the pressure sensor and replace it.i do not know your level of skill to understand this.you may need a garage to do this.
P1762 1T CCM 1996-2003 Cherokee, Grand Cherokee
Governor Pressure Sensor Offset Volts Too High/Low Conditions: Key on
or engine running. Gear selector in Park or Neutral. PCM detected an
out-of-range Governor Pressure Sensor signal for 1.3 seconds. The fault
must occur 3 times on one trip to set a code. Possible Causes: Governor
pressure Sensor VREF (5v) circuit is open Governor pressure Sensor
ground circuit is open P/N switch is damaged or has failed (not
operating properly) Transmission fluid has excessive debris or it is
contaminated PCM has failed
HI. Ok, this may be a false reading. In most cases, driving into a large puddle in a rainy situation , will cause this false reading. I would reset the PCM and drive it for a while to see if the code returns. if it returns, simply, replace the Governor pressure sensor switch and solenoid. the total price, including parts and new trans oil, will be around $165.00.
Your right about the two codes. It's really a transmission part.
As soon as you open up the transmission pan, it right there.
But, I would leave this up to a transmission place. It may need a special type of calibration tool for the new sensor.
