On my 1999 Dodge Durango 4WD 5.9 liter is showing code P0753.?

I have replaced the trans control solenoid and the trans speed sensor and neither one helped. It blows the 20 amp fuse in the power distribution center and shows the same code. Could anyone give me some more information on how to check the wiring for a short or any other suggestions on what to look for?
No I did not replace the wiring harness with the solenoid. I was unable to get to the top connection on it to change it. I did not know how to get it out. Is there a way to test it? Or how do you get to the top plug? Is there a way to test the PCM or use a jumper wire to check it?
 
Sounds like you have a short in the wiring harness. Could possibly be the PCM but unlikely if that's the only code set.

Did you replace the harness with the solenoid pack?

SYMPTOM
P-0753 TRANS 3-4 SHIFT SOLENOID/TRANS RELAY CIRCUITS

WHEN MONITORED
Continuously with the key on.

SET CONDITION
This code is set if the voltage detected on the 3-4 Shift Solenoid Control Circuit at the PCM is different than the expected voltage.

POSSIBLE CAUSES


Fused B(+) feed to the trans control relay open
Transmission control relay defective
3-4 solenoid wiring harness intermittent def
3-4 solenoid wiring harness observably def
Shift solenoid control circuit open
Shift solenoid control circuit short to ground
Solenoid and harness def (solenoid connector)
Solenoid and harness def (solenoid control ckt)
Transmission relay output circuit open
Transmission relay output circuit shorted to gnd
PCM def (3-4 solenoid/transmission)
PCM def (trans 3-4 sol/trans rly ckt)
PCM def (3-4 solenoid control circuit)
PCM def (solenoid harness and pack)
 
you need to keep in mind before you start jumping wires over on that one you need a wiring diagram on it unless you want do further damage to it,you can easily short it out and burn up some really expensive parts,get a good repair manual for the wiring diagram and be extremely careful,good luck.
