Hello, 1998 Grand Cherokee Laredo, check engine light-code: P1764, governor pressure sensor volts too low. How serious is that? One mechanic said it was a bad sensor, another said it was a bad transmission. Thanks.
1998 Jeep Grand Cherokee V-6 4.0 liter
After 1 mechanic from a national chain said it needed a new transmission, another mechanic from another national chain said it was just a bad sensor or connection. Neither are transmission specialists. In the past, the check engine light on other cars was not a big deal, so should I just take it to a transmission specialist or is everybody yanking my wallet? Again, the code is P1764. Thanks.
Most commonly this means that the governor pressure sensor and transducer need to be replaced,a volt code normally does not mean that there is a mechanical failure, normally this is a sensor issue
I use a fluid evacuator to pull the fluid out of the pan before I remove it so I don't spill it all over, if you do not have one be sure to leave one bolt in but loose on the side that you feel the fluid will drain from best and on the opposite side leave one bolt almost all the way in so as the pan comes loose it will tip to the other side and the fluid will poor out, than when removing the pan the rest of the way be careful since it will still be full of fluid
To avoid overfilling transmission after a fluid change or overhaul, perform the following procedure:
CAUTION: Do not overfill transmission, fluid foaming and shifting problems can result.
When fluid level is correct, shut engine off, release park brake, remove funnel, and install dipstick in fill tube.
I hope that this helps
if you need more information just let me know
