1997 getting code P1776 & PO700 What does this mean


The code 700 is a notice that there is a problem with the trans control module, and code 1776 could be a problem with the low-reverse solenoid inside the trans. Code 1776 can trigger the code 700.
The solenoid would need to be tested.

Code p-0700 / p-0740 how to clear code


To clear the codes is the easy part, you can use a scan tool or remove the battery neg terminal for 5 mins but the codes will come back.

the PO700 is a code that tells you there is a ****** code which is the PO740 code. the PO740 code means the TCC circuit has a problem. this could mean there is a bad tcc solenoid or wire to tcc.

I would have this problem checked out asap. these vans have a lot of problems with the transmissions . your problem may be as simple as a solenoid pack problem. these vans with transmission problems can get costly, having it checked now would be wise. if you had a scan tool to get all ****** switches and solenoid value readings i would be able to help you check it but a ****** shop can check it with in an hour. good day.

I have a 2000 Chrysler Voyager. The engine light came on and the following troubleshooting code - PO700 and PO605. Can you tell me what these mean?


The P0605 is an internal failure in the transmission controller. This code sets when the tcm fails one of its internal self tests, and i think the only repair is to replace the module. P0700 is transmission control system malfunction

Code # PO700


all this code means is that the Transmission computer has asked the engine computer to turn on the check engine light, now u must have the Transmission computer tested to determine the reason the check engine light was turned

PO700 PO740, check engine light on. Run a test on


PO700 is a code telling you there are codes in the TCM of some late model cars where the Transmission control module has lost connection to the PCM the vehicals main computer , And basically it happens when the TCM has a issue within itself or the transmission that sets a code and it sends a request for the PCM to illuminate the SES or CHECK engine light.
PO740 is a chrystler specific code that involves your Tourqe Converter Clutch Circuit (specifically The TCC solenoid) this code if not repaired quickly could cause major transmission problems....slipping out of gear....not shifting from first to second properly and just all around trans problems...eventually leading to no shifting at all...I highly recommend fixing it soon.
