I have a 1772 code, I replaced the valve body and the code stayed and the problem is just different.
Before it was like it was always in 3rd or 4th gear accelerating very slowly.
After the fix it accelerates faster.. sometimes, its sparratic to say the least. Even though now it accelerates it doesn't seem like its actually engaging into the gears. All advice is appreciated.. thank you!

So I reset the battery overnight.
I got a c1109 and c1130. I started the car the check engine light was off. It seems like it wont go into first gear but all other gears are working correct now.
Around the block CEL light on back to p1772!
What is going on??

The codes show these are the causes
From 1109

Faulty Anti-Lock Brake System
(ABS) Module Actuator (Electrical / Control Unit)
ABS Module harness is open or shorted ABS Module circuit poor electrical connection Blown ABS Module fuse Low battery voltage
And
From 1130
Faulty Engine Control Module (ECM)
Faulty ABS actuator and electric unit (control unit)
Control Area Network (CAN) communication line
Blown ECM fuses.
After unplugging the Battery it fixed a bit, but the original code came back.
What's happeninh??

P1772 is still complaining about the low coast brake solenoid as I stated in the other thread. The C* codes seem to be wiring and ground issues....which could be causing the P1772.

Follow the FSM on the P1772 issue as it walks through testing the component

So since I changed the valvebody and still no avail I read this online
-Low coast brake solenoid valve is turned “ON” or “OFF” by the Transmission Control Module (TCM) in response to signals sent from the PNP switch, vehicle speed sensor and accelerator pedal position sensor (throttle position sensor). -
So I'm going to unplug and try to clean the tps sensor while I have a new one on it's way in the mail.
I'm currently selling the car to work on my D21.
This will help the resale value for sure!
