My 2003 Caravan SXT broke down last month. One thing led to another and after $600 in repairs and 3 weeks in the shop, they tell me that the issues I had after I picked it up was because this "computer" needs to be replaced. It's part PO4727721AE. They called Chrysler (which I know from the get go it's a no no especially for a car this old) and they quoted them $1000! I don't think so. My van is not even worth that much, it has 167K miles on it. I need to replace this part so my van can last me another year or so until I can get a new car. What do you suggest? In the meantime the mechanic told me I could take it back home until they find the part. Would driving the car like that be an issue? (The gears have trouble shifting in low speed, but once it's 65mph it's fine).

 

You could try your luck at a u-pull for the part or check craigslist for a similar vehicle being parted out.

 

What does the bill say the $600 charge for? If there were multiple problems, and the $600 was to fix something else, then maybe that part of it is ok. But if that's not the case, a $600 diagnostic fee (i.e. fixing nothing) is borderline criminal. That aside, $1000 for a TCM is criminal. The online parts outfits sell TCMs for around $200, programmed for your vin. Or you can take a shot at one from a boneyard for $50 or less. And it's a VERY simple job to install a TCM. Sounds like you need to find another shop asap.

 

The $600 was for several things that was done to the car (power steering pump, speed sensor, belts, a/c, etc). When I took it home, after a day or so, the "speedometer" would flicker between 10-20 mph when the van was stopped at a light or stop sign etc and when I accelerated it to continue my journey, the transmission would "jump" (gears). Took it back and an electromecanic diagnosed that it was the "computer". That's the part # from the pic they sent me. Apparently the transmission is fine, but the computer is messed up.

 

Yes, that part number is the TCM, which is a transmission computer. If you want to stick with this shop, you should ask them why this part will cost you $1000, when they are available online for around $200, which typically includes a 1 year warranty.

 

That part number from Chrysler is discontinued and only one dealer shows one. The price is $410 if it were available. Nice mark up for the other shop.
