HELP! Replaced gov solenoid and press sensor, now getting P1762 and P1764 codes

I have a 98 grand with a 318 and 44re transmission. It started acting up a while back. After driving for about 6 miles or so it would downshift hard and the rpm's would drop and then kick back up when stopped. Only twice I noticed it would start out in second gear and it threw a P1757 code I believe it was. Because of this code, and knowing that the gov press sensor and solenoid are common failures in these trannys, Sunday afternoon I dropped the pan and replaced the gov solenoid and pressure sensor with brand new ones and also replaced the filter and fluid. I took it for a ride when I was done and noticed it started upshifting better when driving and felt better than ever. It wasn't holding gears as long and was shifting smoother. It was still acting up when coming to a stop though, but not as bad. I parked it for the night and yesterday morning got in it to drive and noticed it was starting out in second or third gear all the time and it threw codes P1762 and 1764. I have NEVER gotten these codes before replacing these parts the night before. So now my Jeep went from acting up after driving for a while, to un-driveable. Is it possible I got a bad part? Should I replace the gov press sensor again and spend the money on it? I really need some advice, I've gotta have my Jeep and times are tough right now financially. Any and all advice is really appreciated. Thanks for your time!

Oh also I did unhook the battery and let it sit for a few hours and when I hooked it back up the light was still on and still had the same issue...

Anyone? I'm thinking about dropping the pan again to make sure it's plugged in right and if so I will have to get a replacement. I went with an OEM Borg warner "updated" version. This really sucks. I didn't have either of these codes before I changed these parts...

The updated BW solenoid is not the problem, I responded to your post in the thread I started. Go buy the pressure sensor/transducer from the dealer and install it.

I replaced both the gov solenoid and pressure sensor/transducer at the same time. You think I got a bad one?

You bought your parts through Cascade correct?

Lately it seems that there are several people who have received bad pressure sensors/transducers from them (myself included). They claim to use an OE supplier for the transducers, but after installing a genuine Mopar part and having my problem go away, I'm not so sure of that.

No that was someone else in your thread that bought them from there. I bought them from a seller on ebay with almost 100% positive feedback. Here's a screen shot from my phone...

Hmmm...I dunno. I know the feedback is good, but it wouldn't be the first time that somebody didn't get the correct product on ebay.

I can't remember for sure, but I think my Mopar sensor had the part number stamped/imprinted on it. If you're planning on dropping the pan again, I would look to see if there's any indication its a real Mopar part.

Ok sounds good. Yeah I've gotta drop the pan again because the Jeep isn't even driveable at the moment so I guess I'll but a new mopar one and go ahead and put that in. I appreciate your input and I'll let you know how I make out. It will probably be a few days though.

Yeah, no problem, hopefully it turns out to be an easy fix for ya. I went crazy trying to fix my trans issues after replacing those parts. I easily spent 20 hours troubleshooting and over $100 on top of the cost of the parts. I replaced the vehicle side trans wiring harness (which it did need, but didn't fix the issue at hand), the underhood wiring harness and PDC, warranteed an ECM, wired in a trans relay outside of the PDC, replaced the battery cables, and went through 12 qts. of tranny fluid.

Finally I swapped the transducer out with one from the dealer for only $17 more than I paid for the one from Cascade and the problem went away.

Get it a pressure sensor from the dealer. It should run you about $90.
