We had almost an identical experience to Moody Blues, and now finally it's completely fixed. During hot weather, our 2003 Dodge Grand Caravan's automatic transmission would go into "safety mode" but we didn't fix it due to money. It gradually went into "safety mode" all the time, so we had to take it to a transmission shop. They had to rebuild the transmission. Because we drove it for so long in safety mode, it ruined the transmission. Even after being fixed, we had to take it in periodically due to the "safety mode" problem again. Recently, with the hot weather again, it started acting up again so the transmission shop checked the engine code, and said the code showed that the electrical relay system was off and therefore not sending the power to the transmission. They sent it to a regular mechanic down the street. After about 2 1/2 days, we heard there was a loose connection (wire), that the mechanic unplugged and replugged it, and cleaned around it. Finally, our transmission is working in hot weather. We've had it back one day. It has more get up and go, also. Hope this helps you not to ruin their transmission when it might just have a loose connection in the electrical relay system.

We have a 98 Grand Caravan LE with the same exact problem. We don't want to spend a lot of money or go to the dealership (because they are going to tell us to rebuild the trans no matter what with the mileage we have on it). Can you please tell me which specific wire your mechanic replugged in and cleaned around so that me and my dad can try the same thing? Thank you very much.

Same problem on 2002 Voyager, 31TH transmission, didn't shift out of 1st when in Drive, no OBD codes. Solved by replacing the governor. As a part of governor valve, there are 2 pistons moving by the centrifugal force of the governor rotation (one of the pistons is also spring-loaded). That way the governor senses output shaft speed and sends that information back to the valve body as a variable pressure. Both of those pistons are moving in their "cylinders" cut in aluminum case. Even though those pistons and cylinders are lubricated by transmission fluid, one of those cylinders got chaffed and its piston got stuck (the one without spring load). By replacing the aluminum case only, the problem was solved. Aluminum case for the pistons was taken off a Neon transmission from a junk yard. Note that Neon governor has different weight of the pistons, most likely the shifting speed is lower because Neon is lighter vehicle than Voyager. So only the aluminum case was taken off of Neon governor; the rest of the governor was kept original Voyager, including the pistons. This post may be too late to help tiger125, but anyway here it is for the record and future forum search.

Thanks for the info. I will call their CS. Maybe we should call NHTSA, you think they can help expedite this process? I'm hoping this is something minor. I'm planing to keep the car over 100K.

I think you have another problem, namely a cold solder joint on your speedometer circuit board. Next time this happens, bang your fist down hard on the top of dash above speedometer.... if it clears up that is the problem. Remove and fix, common electrical problem for this vintage van. Look for my other posts on this issue.

Hello Rick, i also have a 2008tc. DId you ever get a solution on how to check the level. I think taking it to the dealer is stupid to check oil. I notice seeping between the gaskets when i went to change the regular oil. I want to add but not sure which type of oil to add.

We are already having the same problem again, so I'm going to take it back to the transmission shop and find the exact code and name of the part on Friday. Our transmission is under warranty but the part was not part of the transmission so we will have to pay to replace it. I remember last time the transmission guy thought the part was about $60 to replace it but we had no money at the time. This time I will find out the code and just replace it. My husband also said that I was wrong about there being a loose wire. The mechanic told him he had just cleaned around the suspected part. There wasn't a loose wire. I'm going to investigate a little before taking it in. I don't know what "electrical relay system" means. "Ugly guy" mentioned replacing the Speed Idle control (Air Throttle Control) and said it was $66 for original part. Are these the same part? I don't know. I will investigate. My husband is pretty mechanical about normal things on cars. I don't know too much. I will post more after problem is resolved.

We've had the van back a week from the shop, and the problem seems fixed finally! The mechanic said it was the engine control unit that was the problem. The first time they replaced it, I had to return it the same day because it still had the same problem. When I got in the van to go somewhere, it did a hard shift into reverse and when I put it in first, I saw all the boxes lit up. It also drove in "safety" mode. The mechanic said sometimes they get a bad engine control unit, so they would return it and ask for another one. They replaced it, and test drove it a lot, especially in hot weather. So far, so good.
Since we drove our van so much in "safety" or "overdrive" mode so much last year when the weather was hot, it ruined the transmission so that it began slipping, etc. and we had to have major work done on the transmission, plus we had to have this engine control unit replaced this year. The transmission work was $1,700. The engine control work was $600. Better to pay only $600 and not drive it in that mode, instead of both. The repair cost breakdown was $80 for diagnosis, $324 for replacement engine control unit or module, plus about $200 labor for replacing and reprogramming the unit. I asked the mechanic if there was a warranty on the part and I think he said 4 months or 96,000 miles.

Keanezra, I missed seeing your June 07 post until today. I am today sending the second letter to the Chrysler Customer Assistance Center reporting the problem and requesting our van be repaired. I sent the first letter May 23 and received a letter dated May 26 advising our case is being reviewed. Neither us or the Dealer has heard back from Chrylser about the problems with the transmissions. If I can't get repair help by trying to deal directly with Chrysler (and the Dealer), I will contact the NHTSA, our State Division of Consumer Affairs and maybe the BBB. I would certainly like to have any updates that you might have about the transmission problems. Do you know of a practical way to get other owners to join together about this problem?

One owner had just found out that cam phasers could be the problem. I know phasers could cause shuddering/rough shifts. I suggest having your dealer check it out. I'll bring mine asap.
