Here are a couple of things you can try for free if you are mechanically inclined, if you are unsure don't do this yourself.
i can't think of the exact wording for 1787 but is either shift control or torque lock up.
1)If this is the first time you have had a scanner on it since the new tranny was put in, this code could have been set when it did not shift that day, it will stay in the memory until cleared manually, if it only happened once,it could be why it did not set the check engine light.
2) Now you are going to have to get dirty,Dodge is known for having leaky connections on the tranny thus allowing fluid to get into them from the inside. Get yourself a pair of safety glasses with side sheilds, a small can of aerosol brake clean, and a can of compressed air (the kind you clean computers with) and a tube of di-electric grease.
Do this one connector at a time,PUT ON SAFETY GLASSES,disconnect then spray a little air in them to remove fluid then spray a little brake clean on them do not soak them then spray air to dry, repeat this 2 or 3 times apply a liberal amount of di-electric grease re connect

You can save yourself some money by doing this yourself or have a friend do this for you
If you want to erase the code, disconnect the negative battery cable for 30 minutes, do this while you are cleaning the connectors,
If the code comes back up,it ia probably internal

Hope this helps

I have a 3.1 litre 1999 dodge grand caravan, there has been a smell from the transmission, like it was leaking when its driven for a while. we took it to mechanic and he said ther weren't any leaks. now...


Dodge has a reputation for transmission problems in the past. The trans can be replaced or rebuilt but there is likely no simple fix for what you are describing. Make sure in the future to have automatic transmission serviced at least every 30K miles to help them live a long happy life and avoid replacement/rebuild cost.

What does these codes mean P1781, P0731, P1784 AND P0700 AND HOW DO I FIX THEM.


p1781 is manufacturer control transmission, p0731 is gear 1 ratio incorrect, p1784 is manufacturer control transmission, p0700 is trans, control system malfunction. all of these codes refer to tranny.This code normally points to a faulty transmission control module, but this is an expensive part and you should have an experienced Dodge technician diagnose the problem first. or a transmission specialist. the other codes are probably associated with the p0700 code. have a good day !

My 1997 grand caravan did not pass the smog check because of p1787, what does this mean? how can it be fixed?


It indicates a transmission problem. If your not experiencing problems in that area with shifting or anything, then I'd consider having a transmission filter and oil change, using ONLY ,Mopar fluid from dealer,and you might as well get filter there as well. It will probably be as reasonable a price as the rest. After change, have code erased to see if it comes back, and if it does, you'll have to get it to the dealer and have tranny checked by them to isolate the problem before it cost big money for a repair that could have been avoided.

2002 Dodge Caravan Transmission not upshifting


Hello,
I also was concerned about my tranny in my 1998 dodge caravan. I replaced the fluid & filter and it worked for a while. I finally had to bring it to AAMCO Transmission and they gave me a free evaluation of it & an estimate for the job. I had the option of ignoring their evaluation results and bring it home or just bite the bullet and have it repaired. I thought I could get a lot more miles out of it so I had it fixed for $1400 with no regrets.

Perhaps if you can find a similar place with free evaluation & estimate then that would be the thing to do as you seemed to have covered all the other bases.

Good Luck!
