Replaced
my transmission and still with the same problem code 1768,1773,also the d4 light blinks,speedometer not working. I looked for power at speed sensor connector and there is no power there no wonder if computer is bad,fuses are good.Trans is in limp mode I can drive it in 1 and manually shift it but only takes 2 speeds,If I can find a wiring diagram for the pcm that would help me.

 

When the transmission was replaced were the solenoids reused? If so, check Clutch pressure control solenoid valves A & B with a VOM. You should read about 5 ohms. Also, was the torque converter replaced or reused?

 

P1768- Problem in Torque Converter Clutch Solenoid Valve B Circuit
P1773- Problem in A/T Clutch Pressure Control Solenoid Valve B Circuit

Looks like there is an issue with Valve B. If the speedo is not working it may be the VSS but that would have set a P1791, so the speedo may be out.

 

Converter was change but reused the solenoids I will check this solenoids,about 5 oms

 

Actual reading on both of them 5.2,5.3 ohms

 

Actual reading on both of them 5.2,5.3 ohms,

 

The question is why speedo is not working and pcm is not giving me the code,also no power on harness for speedo

 

If the VSS is working and the PCM sees it then it will not set a code.
Might be a wiring issues where the speedometer connects, or the speedometer may be faulty.

 

I want to take a moment and thanks madmike and jdowens for the help and to let you guys know that my problem was a wiring issue in between connector "d" and the harness that connects pcm and tranny, that's why there was no juice on the sensors sppedo wasn't working etc...I fix the harness and wires and everything came back to nomal tranny is shifthing real nice...again,thanks guys...
