PCM Transmission issue?
1999 Dodge ram 1500, 5.9 V8 Automatic
Alright here is my previous post, I had a PCM Wireharness issue, I repaired the Wire harness and it resolved my No Bus and CCd issue. This issue has occurred after repair.

Before I resolved the PCM issue, the truck shifted fine, When the truck as in drive, it would shift normally 1-3 including overdrive. Never had a check engine light. When I fixed the PCM issue, I got a check engine light, Code, P0753 my symptoms are as follows:
When truck is 100% stopped, in drive it is VERY sluggish like its starting out in 2nd or 3rd gear? I manually shift into 1st or 2nd gear and it picks up and drives with no issues then I put it back in D (drive) it will no longer have the sluggishness and shifts fine. I can turn overdrive on/off but it does NOT engage It does show on/off on dash. From what I can tell, at highway speeds the truck does not shift into overdrive and will not downshift.
I have been following this post with no luck, I swapped the relay from Horn to trans, no luck. I checked the trans fluid, it was low, I filled transmission to proper level, reset ECM, turned truck back on, after 3-5 seconds check engine light is back on. I checked the wire harness and there are no exposed wires. I swapped out the PCM, no luck same issue. I cleaned the electrical plugs on the transmission, no luck. The truck has a repair kit for the transmission wire harness (Solenoid repair harness), to be safe It off, rewired it properly. No luck. I am not sure if this is a power issue, Possible power issue or ground issue? Again it did not do this until I repaired PCM Wire harness.

Shift Solenoid A is for O/D. (as that is the only shift solenoid in the trans.....) If you are also having issues with the trans shifting 1-3, then that code is likely just a symptom of some other problem. Verify you are getting 12 volts down to the trans. (engine has to be running for that.....) Also verify you are getting the 5-8 volts for the pressure sensor.
