2004 Intrepid SXT 3.5L In Limp Mode
I know that there have been many, many, way too many posts on this problem but I am at my wits end and out of money on this one with no resoultion. I have a 2004 Intrepid SXT 3.5L that goes into Limp Mode after driving for about 20-30 miles. It gets stuck in 2nd gear when I slow down to 35-40mph. Once you put the car in park and restart the car it's fine until you slow down again.
Now that I've just reiterated the same problem that many people seem to be having here is what has been done to the car while it's been at the mechanic for the past 6 weeks.
First step was to do a trans service and check the valve body date code. It fell outside the TSB's recommened date so they replaced the entire valve body. $1k later problem still there. Generic P0700 codes given each step along the way.
Second step was to completely rebuild the trans. $2,500 later and the problem still occurs. I was told that both speed sensors where replaced during the rebuild. (I suggested they try this because of the many other forum posters with this problem)
Third step was a suspected faulty Solenoid Pack within the new Valve Body. They replaced that and still the problem occurs.
Fourth step was to swap the entire trans out with a new rebuild. No dice, the problem still occurs. They roadtested the vehicle for many miles after doing each step.
Fifth step (remains to be seen what happens) take the car to Chrysler and have a complete diagnostic run on the computer and electrical system.
Does this make any sense at all and are there any other steps that could concievably be done? They claim if it's the computer I will be out another $1,200 for a total of $3,700 plus tax in repairs. The vehicle barely blue books to that amount.
Any suggestions are greatly appreciated and I promise to post what the fix actually was "if" it ever gets fixed. I notice that alot of people ask for assistance but never follow up with the fix.
