QuestionQUESTION: Hi Roland,
My 2002 Chrystler Concorde went into limp mode after a very long drive a couple weeks ago. I had my fluid and filter changed and my transmission tested for codes at transmission shop, none came up. After driving a good amount this weekend, I went into limp mode a few more times. Each time I turn off the engine, it resets and the car runs fine for a while. A few months ago I had the main computer of my car replaced and it caused a few problems with my headlights and break lights because of programming issues. Have any thoughts of what may be wrong with my transmission and if it's possible that it could be in correlation to my main computer?
ANSWER: Hi Michael,
If it goes into limp-in it will almost always set a code. Try a free readout at an Autozone parts store, which they usually will do gratis. Then let me know the code. The transmission relay being flaky will also cause it to go into limp-mode but there is a code for that too (

QUESTION: Hey Roland,
I took your advice and the following codes came up. P0700, P1776, P0871
ANSWER: Hi Michael,
There are several possible causes for the these codes:
Check fuse Q in the power box under the hood and look carefully even if it appears to not be blown to see if it might have a subtle crack in its internal wire that might open and then close spontaneously with use.
Then try swtiching out the transmission control relay (3rd from the inboard edge) with another relay in the box that shows the same part number but is not critical to driving the car.
See if that improves things.
If not, then I would believe that the solenoid pack should be considered for changing out which can be done without removing the transmission. It is on the driver's side of the transmission. The 0770 code is a general notice that there are other trans codes to be noted. The 871 says there is an issue with overdrive pressure switch circuit and the 1776 is for a problem with the low/reverse pressure switch circuit. Both of those could be due to an issue with the fuse or the relay or actually a problem with those switches. The wiring to the solenoid pack should be checked to see that the switch wiring circuits havenn't been damaged, however. In any case, I don't see a need for a rebuild in these codes. Look for an honest competent shop to check these issues out.

QUESTION: Roland,
I checked the Q fuse and it was fine. I took my car to a transmission shop that had an opportunity to rip me off in the past but didnt. They checked for codes and came back with 1776. They told me I needed a new Solenoid Pack and Value Body based off nothing but the 1776 code. They quoted me for $650.00 plus tax. My concern is it might be a smaller issue. What do you suggest?

Hi Michael,
If there were no issues with the wiring then I would agree with the solenoid pack repair/replacement diagnosis. To do that you do have to remove the valve body to which it is attached. My only question would be whether the valve body also has to be replaced? Why not inquire on the cost of doing just the pack and then seeing if that solves the problem and if not then doing the valve body as a separate repair? There is obviously going to be a greater cost if you do both separately, but what are the odds and cost saving of changing only the solenoid pack as opposed to doing both at once? Are they certain you need the valve body and was is its cost? Might it be serviced rather than replaced? I would be curious to know what you learn and what you opt for and the outcome.
Roland
