Chrysler Repair: Code 41 from the transmission controller, testing electrical circuits, solenoid pack

Question
QUESTION: Hi Roland. I previously described my problem with the 41TE Chrysler transmission I have been having. The code 41, L/R solenoid circuit. I am not sure what to do anymore after testing and replacing the wire from the solenoid to TCM connector. It still has not corrected the problem. In your opinion, could the new solenoid pack be defective? It was installed prior to replacing the battery. Could the battery have been shorting out and possibly damaged the solenoid pack? The ohm readings seem to be normal but maybe under load it is failing. This has been a real puzzle. The only items left to replace are the TCM (with new), another solenoid pack, and the valve body. If it was indeed the valve body, would there be a different code other than the code 41?

ANSWER: Hi John,
The best way to sort this out is to go thru a test procedure for code 41 which should sort out the possibilities and give you the answer. I have the 6-page procedure from a '92 trans manual which is no doubt applicable to your vehicle. If you will tell me a postal mailing address I will xerox and postal mail them to you. You can do that by using the thank/rate tab where there is space for a comment. I think you should assume the 41 code is correct, particularly if when you disconnect the battery for a few minustes and then drive the car you still get limp in and a new code 41 (in addition to a 12 code for the loss of the battery power recently). So that is the approach I would recommend. I don't see how the battery could damage the contoller or the solenoid pack unless it was hooked up backwards.

QUESTION: I received the test procedure you sent. Thank you very much. While I'm familiar with testing electrical circuits, I am not familiar with the method described using a DRB11 to "probe" the circuit. Is this the scanner that one would connect to read the codes? If so, I guess I will have to have someone with a DRB11 scanner to do this. Am I on the right track?

Answer
Hi John,
Yes, but I think almost all of the measurements are resistance measurements which you can just as well do with a digital volt-ohmmeter. So try that, and if you don't get a reasonable answer just note it and continue. Then consider the big picture when you get thru the whole procedure. I would just measure between one of the ground wires and the test point. You can probe a wire if the connector has to be attached to do the measure by inserting a very fine staight pin thru the insulation.
