1997 dodge intrepid dtc p0700 and p1782

as stated in the title i have a 1997 intrepid 3.5 and i am pulling codes p0700 and p1782.
i was planning on replacing the transmission control module, as it doesnt look very difficult to do.
is this a likely cause for those codes? any feedback would be greatly appreciated.

From what I've read, P0700 can be anything from the TCM to the input or output sensors to the TCM relay to something else.
I'd start with swapping out the TCM relay first.

is dodge hiding it somewhere else?

P1782 Chrysler 2-4 Pressure Switch Check which is another transmission code that may point to the solenoid pack. Unfortunately if it is the solenoid pack, it is internal on your car I believe.

There is a TSB #21-02-98 that describes a new software release for the TCM. Among the enhancements is desensitization to intermttant pressure switch, speed sensor and gear ratio faults. It will still set the fault code, but won't put the trans in limp-in until the fault occurs several times.
The bulletin asks that the PCM also be at it's latest revision.
Has the ATF+4 and filter been changed recently? Cooler hoses dry?
TCM's and solenoid packs have a low failure rate. If there is an electrical problem, I would more suspect wiring first.

i have not changed the atf and filter since i got the car in july. .and it does have a coolant leak from one of the hoses where it meets the radiator.
do you suppose a bad ground could cause this?
