Guy, I'm having some kind of problem with the forum. I got your first message, now can't go back to look at it, or others. No option that I can find, control panel, nothing, will do it. Maybe use PMs instead.
Now, having found this post, which is what I saw in the notifications, now gone: Sorry I was a little short with you. Usually, "don't have a clue" means individual is at a loss; no matter what I can say, won't instill the experience and probable technical ability needed. Now, let's look at the original problem, give me a bit of time:
I have a Transmission Solenoid problem. First, I was getting an error code of P0751 for Solenoid SS1/A. I replaced the whole harness and Solenoid A and car worked for a little while. Did it work AT ALL, before solenoid replacement? Yes, it worked before the solenoid replacement, just not well, like now.
My check engine light came on again and I did another diagnostic and received a code P0761, which is the SS3 solenoid or Solenoid "C". When I got home, I did another diagnostic on now received a 2nd error code of P0751, Solenoid SS1 or Solenoid A. So, now I am a little confused. Can One solenoid affect the other? No. But solenoid malfunctions can confuse the PCM, and then codes get thrown which are misleading.
Could Solenoid C have gone bad and then affect Solenoid A or vice versa? Extremely unlikely.
I never previously had a Solenoid C issue, only A, now I have them both after a full harness install.
Both Solenoid C and A are replaced, but received same error codes again when driving about 400 miles, first P0761, then P0751. I thought maybe it was the PCM, so I replaced the PCM, and it worked for awhile, then bam, I am getting the same errors, so I do not think it is a PCM issue. Does it always work for awhile after attempts to remedy? It always works after I switch the PCM's, then it goes downhill and then I get error codes
I do not think it is the PCM Power Relay, but I could be wrong. Power relay failure kills everything.
I know I can test the voltage on the Solenoids, to see if they really are bad, correct? No. Presence of VOLTAGE at a solenoid, or any other "output device" of the PCM, tells you NOTHING about the condition of the device, save for that it is not shorted to ground. I am not understanding, JK080 and a others on here have stated that I can check through the PCM and the PCM Power Relay the Solenoid to see if it works or outputs the correct ohms, I have seen others do this test. You are saying the test is invalid and tells nothing of the solenoid and if it working or not?
Or is there something else that I may be missing, connection from the harness to the PCM perhaps or something else? I checked all fuses, great, all relays work, but I never did test them, just visual. HTH can you tell if relays are "working" by looking at them? Can you tell if their contacts are properly opening and closing, delivering power to the devices they control? Yes, I visually checked the harness for any issues with broken connections, bent wires rusted or corroded connectors, partially broken wires or loose wires. I am not sure why a visual check is not warranted.
Is there something I can do to do further testing? Anyone know if I am missing some steps here or looking in the wrong direction?
You did not indicate in the start of the thread, exactly WHAT was the transmission doing, or not doing. Expecting to solve as complex an issue(s) as might exist here, by just viewing codes is like pissing against the wind.
I know I haven't helped, but then I'm not alone, right? What was the original problem(s) that led to all this? imp
I am not sure if you read through the original thread, but I posted this in one of my responses to JK080:
When I last spoke to JK080, I was hoping he could give me a little more direction in how to take off the covers to the Overdrive Servo's and the like as it seems to need a special tool which I can barely find on ebay. Also, I have to remove part of the exhaust to get to it, which is not an issue, if I felt comfortable in taking off the Overdrive Servo cover and working on the components inside.
