Thanks. I guessing you're talking about the wrapped wires running from the TCM/PCM down along the firewall.
How does a person test these for a short without physically taking the wrapping off and inspecting them?
Part of the reason I never believed that a short was the problem was how all this started in the first place and the fact that my issues never happen in a short drive of 5-10 miles, but instead every time its when I'm out for a couple of hours. And not really highway driving but basically 2 lane roads and going 40-60 MPH with some hills.
You wouldn't expect a street driven and clean engine bay with no disruption of the wiring harness to suddenly have a short in a protected wire.
The transmission guy keeps telling me that he thinks its a computer problem even though he could make a lot of money by rebuilding the whole thing and not just changing the solenoid pack which cost me $700. He has just suggested that the new computer will "learn" and solve the issues, although since I've changed it (twice), I've had at least 5-7 different times of it going into limp mode and coding 1775 and 1776. So the "learning" thing doesn't seem to be happening.
He actually has another 2005 customer with the same issues. And I directed that person to Wranglerfix as well. Not sure if he ended up getting a new PCM or not.
But any advice you can give on testing the wiring would be great. Thanks
I am in agreement with what everyone has said regarding checking your wiring. The alternative seems to be way more expensive so why not try that first before even considering a full tranny rebuild/replacement?
As far as only happening in the heat, wiring gremlins can manifest themselves in all sorts of weird ways and it's smart to rule it out if all possible and feasible.
My thought process...
I am in the camp that the fundamentals are where problems usually exist. For example, bought my tj off a girl who told me her main bearings had gone on her engine, which she said was confirmed by her mechanic.
I picked up the TJ from the mechanic's shop and spoke to the mechanic who confirmed what she told me. Told me it wasn't worth putting any time into that engine.
The end result was that the engine had a lot of smaller issues, but the true culprit of the jeep not being road worthy was her that she had a broken timing chain spring and leaky power-steering hose that made it look like an oily blood bath in her engine compartment. In this case, the mechanic looked at the oily mess, the noise, and didn't check the basics, and called her jeep dead. Ended up being good for me, but bad for her.
Not saying it can't be a bad tranny, but resist the urge to jump to conclusions without hard data to prove it, or hard data proving simpler things are not it.
Based on what I have read, and what you wrote, data tells me it's probably not the valves UNLESS your shop didn't do what they said they did, you very unlucky and got shity parts, or these are some other things that is making them fail fast.
Since you replaced them based on your receipt, check the wiring or pay someone to check it for you.
As far checking the wiring( never tested the exact circuit you are testing, but have a multitude of others.), is simply look up the wiring diagram, find the ends, IE where the wires originate, and any junctions that have connectors you check and check for continuity between the ends using a multimeter, and for shorts to ground. If this is beyond you, I would pay for that check before I paid for the replacement tranny.
