Govenor pressure code with erroneus shifts

[hulkmn069]

on my 99 i'm getting the trans gov press code p1757 and it's not been shifting correctly between first and second. I am wondering is the govenor and it's components bad and if so how much should i be paying to get it fixed... i'd do it but i'm afraid of auto trans.

The problem could be the pessure solenoid or pressure sensor could aslo be the govenor. You have to drop the Trans pan to get at the solenoid or sensor. You will need a manual if you are going to do it your self. My guess is the sensor and probally 2 to 300 at a Trans Shop.

thanks for the reply i went to a shop and already the first thing he said was 2200 for a rebuild so the quest goes on.

I don't know how similar a 99 is to my 95 but I just went through the exact same experience. My 1-2 shift was messed up, shops say I need a rebuild, I do more research, decide to swap out my Governor Pressure Solenoid and Transducer and now my trans is shifting back to normal. I did the swap myself but I've also been tinkering with cars for 20 years. It's a very easy swap but if your not comfortable, you might buy the parts from the dealer then go to a shop, tell them you only want those parts changed out and to give your old parts back to you. You might also give them the MOPAR fluid to refill your trans with. My transducer and solenoid ran $300 but your 99 parts might be cheaper. For reference my trans is a 42RE.

In case you are wondering......and remember yours may be totally different......I dropped the pan, then the filter. Disconnected the wiring harnesses from the transducer and solenoid. In my case, the solenoid and transducer are mounted to a cast/machined aluminum housing. Housing is held in by both hex and torx head bolts. The housing assembly drops straight down. You can now see the clip that holds in the transducer in the side of the housing. The solenoid just slips in from the bottom. I cleaned my pieces with electrical cleaner (no residue) and sprayed the mating area on the trans. replace the housing, torque the screws and hook up the wires. Install new MOPAR filter and gasket and refill trans. It's a messy job but I knocked it out in about an hour and most of that time was letting the fluid drain off the valve body. Good luck!

thanks for the info i am definately going to look into it more i am going to try to find a trans book on this and possibly do it my self. i am not incapable by any means i am just inexperienced in the trans dept.

how much are the parts for this and can you get them through NAPA etc. or just the dealer??

[1BADGTO]

I bought mine through the dealer and was $300. I'm sure aftermarket is cheaper but this is a job I want to only do once. I've seen these parts on eBay stores for a little less than the dealer but I don't know if it is an OEM part or not. My parts from the dealer came in sealed baggies with parts soaked in tranny fluid.

hey, can you post part numbers as well, thanks

Do not use aftermarket solenoids,the suck!!!!!!!

As for a rebuild if the trans has large amounts of metal in it the new solenoids will fail soon due to the fact the transducers and solenoids are magnetic and pick up metal.

also.... most important...it cost me $700.00 to find out that an independent trans OH shop used a metal retainer on the transducer and gov solinoid, it grounded out the expensive parts to junk right off the bat , and he did this 3 times ..went to the dealer and he said the retainer had to be non metallic , and that you do not put steel parts in the electronic transmission, the car runs like a young pup now ... lesson learned the hard way

well all i know is that this is going to be a bigger headache than i was hoping for ah well
