  • Incorrect transmission fluid (cost: $50-60) - Most COMMON PROBLEM! (even in 2010)
  • Computer needs retraining (try this as soon as you’ve changed the fluid)
  • Solenoid pack (cost: about $60-$160 plus labor. Might be clogged and fixable.)2ND MOST COMMON PROBLEM
  • Ground strap broken/missing - may be misdiagnosed as needing a new transmission and/or computer.
  • Clogged hydraulic “brain” ($0 to $150)
  • Bad input sensor (common) - “Can be seen on scan tool screen as input rpm —if it’s 0, replace the sensor.”
  • Computer firmware needs upgrade (Chrysler dealer should do this for free but might run up to $200)
  • Incorrect filter used in last fluid change
  • Loose electrical connection
  • Torque converter

I have my friends '02 Dodge Caravan, it's showing 2 trouble codes on my scanner, P0700 and P0605. I've already changed the fluid and filter, no change. Switched out the Shift solenoid assembly...


Get it to a dealer or a trans shop and see if the tcm will communicate with a scan tool, the po700 dtc means it's strans code and the 605 normally means the tcm is shot! I see it more on sebrings then Neons but if it's the same engine and trans combo it's quite possible. If you drive it like that you can really damage the transmission so get it fixed asap.

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 !

After getting the up to about 55-65mph then slow down to under 40mph it seems that the trans will not go back in to over drive, and now when it happens I get a low end tap as I go over 45mph and a light...


You need to have the solenoid inside your transmission replaced. That is the P1776 code, and it is what is causing the P0700 code.

Also, make sure to do a transmission fluid flush and change, along with changing the transmission filter.

Codes P0731, P1782, and P0700


It means you have some or just one sticking or defective solenoid in the trans valve body. You will need to take it in before you become stranded and or destoy the transmission. Even if the fluid was low and you had these symptoms these codes would not be related. These codes are electrical related, not pressure

Car is still drivable, but code P0700 is coming up... is this repairable??


The p0700 is a generic code for a transmission issue. If there is a Auto Zone around your area, have the car scanned for any DTC codes since it's free of charger there. Check the transmission fluid level after going for a drive to warm it up. Make sure that the transmission fluid is not low and that it's not burnt. If your due for a transmission service, take it to a transmission shop to have the transmission fluid and filter changed. Ask them to hook up the tech 2 scanner on the car to look for any DTC codes that indicates why the P0700 was triggered. Good luck and hope this helps, most transmission shop will scan for free of charger if your getting the transmission serviced there. Keep me posted, be glad to help.

Engine light on code p0732, p1782, p1787 and p0700 twice


P0732 Gear 2 Incorrect ratio
P1782 P/ES Circuit Out Of Self Test Range
P1787 2-1 Downshift Error
P0700 Transmission Control System (MIL Request) Malfunction

Here is the deal, u have some serious transmission related faults, in order to sort this out u will need to take this to the dealer, allot of testing is required to get to the bottom of this, if I had to guess I would say the trans is going to have to be overhauled.

RAM 1500 OBD CODE p0700/p0740


I had the same problem and a friend suggested that I get a filter kit for the transmission. My dodge ram 1500 stopped pulling and had to be towed home. I got a filter kit for the transmission and now the truck is runniing good again and the transmission is shifting ok.To get the code off by going to
Auto Advance and used their code reader to erase the code. My truck has 249K on it and I know the trans will not last forever, but as long as it is running ok. I will live with the codes but make sure the trans fluids are changed every 10k.
