would replacing the seleniod get rid of the sluggishness?

 

Cross connected or bent pins in connector. Also, did the solenoid and pressure sensor connectors seem to fit correctly?

Wires are crossed, pinched, or not connected tight.

 

Connectors were good and everything fit together with ease.

 

Check and see if you are indeed getting 12 volts back on the sensor signal wires.

 

Today replaced Governor pressure solenoid, and sensor. 2 codes disappeared. now I am stuck with the p0753 and p1763. from what I can tell is its in Limp Mode. Auto zone says 0753 relates to the actual shifting solenoids inside of the transmission.

 

First off, how many miles on the unit and how much sludge on the bottom of the pan? Second off, here's the definitions for your two codes:

P1763 Governor Pressure Sensor Voltage Too High
P0753 - Shift Solenoid A Electrical (either high/low voltage, no response, or the vehicle is in a gear different from the one the PCM is attempting to select or thinks it should be in)

What this tells me is either a connector somewhere isn't hooked up right or all the way, such as the 8-pin on the outside of the tranny, or the one connecting to the valve body, or the internal harness has somehow been damaged, either by being pinched, or (on 100K+ or trannys that have overheated) the internal harness rubber on the wires has become stiff/brittle and so when it is disturbed it breaks causing a short. If you are SURE that all connectors are CLEAN (NO grease, ATF, dirt, etc.) and TIGHT, I would begin to wonder about the internal harness. And yes your transmission has been forced into limp mode. Hope this helps.

 

From my experience with a similar but worse problem, the torque converter clutch refused to unlock, which would cause a sluggish feeling, also if the tranny is in limp mode (either 2 or 3rd) it will feel somewhat sluggish.

P1763 code can show up from shorted wires on downstream 02 sensor. I know, what does that have to do with the tranny. Evidently it's on the same circuit path to pcm and is not listed as a possible cause on most (look up your) code sites.

 

I want to thank everyone with their assistance. Its fixed and working, no codes. Now I am officially calling myself an idiot! The problem was the connector on the outside of the transmission, it became dislodged when I installed the o/d lockout solenoid. Connected it and cleared the dtc's and it works like a champ. Thanks again.
