I replaced the solenoid torque converter checked the wiring thoroughly new filter and fluid tcm still same issue it goes into failsafe mode I am out of Ideas. I do know what the codes mean
P0700 Transmission Control System Malfunction
P1776 Ignition Retard Request Duration Fault
SOURCE: Error Codes P0700 and P0605
0605 is for an Internal Control Module Read Only Memory (ROM) Error. This is typical of a malfunctioning computer. If the computer is bad, your retrieved codes are probably wrong anyway. May need to replace computer, drive, then see if if your check engine light returns.

Hi I'm litoshop these problems your having are from the transmission p0700 is the transaxle control and the 1776 is the solenoid latching back you have to go into data and test drive with scanner on data and see which is the solenoid is really making the problem good luck if this information has been useful please let us know thank you
SOURCE: My Grand Voyager keeps getting codes P1776 P1784
Code p1776 is solenoid switch valve latched in low/reverse position. Valve is located in valve body not solenoid body. The possibilities are:
the low/reverse pressure switch itself is bad
the transmission control relay output circuit is open
the control circuit (sense) of the l/r switch is open, shorted to ground or shorted to voltage.
The control relay's output is on pin #6 of the 8-pin plug of the
transmission (red wire); you could verify that the wire has 12V on it
when you are idling (and I guess I would put it in gear with the brakes
applied). Also examine/shake the wire for intermittent connection
possibility.
The solenoid sense circuit connects pin # 8 (light blue) to pin #50 of
the transmission control module. You could check that connection and
monitor it for voltage to fluctuate between 0V and some measurable V
when the trans is shifting normally, and to loose that fluctuation when
it is not, which would verify the circuit is OK.
If that proved to be OK, then I would suspect the switch isn't responding and needs to be changed.
The solenoid box is removable after you drop the pan and remove the
valve body, and so it would not seem to be an horrendous expense
(compared to a rebuild). I haven't done this myself so I can't comment
on doing-it-yourself.
I would try to find a competent independent shop that know the Chrysler
trans and discuss it with them as to the cost of replacing the l/r
pressure switch as the alternative
The code p1784 is about the switch that monitors the hydraulic pressure for
operating the low/reverse clutch of the transmission. That clutch is
called into play for all forward gears as well as reverse, so it seems
reasonable if that clutch were not working that the car wouldn't move
in any gear. I would begin by making sure that there is sufficient
trans fluid by inspecting its dipstick. If needed only use ATF +4 but
don't overfill it. Also, just on a chance, take a look underneath to
see if you see any motion of either the left or right half axles (or
one moving, but one not) which would be another reason for no motion
due to a drive shaft disconnection or some such anomaly. Other than
that, your problem could be with the Low/Reverse solenoid switch in the
solenoid pack portion of the transmission (the box on the driver's side
of the trans) being stuck. That can be repaired without removing and
rebuilding the transmission so let us hope that may be the cause. I
would have the car towed to a good independent trans shop that has a
reputation for knowing how to service the Chrysler electronic
transmission.
DTC code p0700 is a transmission control system (mill light) which is related to the other two codes mentioned above.
Testimonial: "you was very helpful on this problem you talked in words that didn't make me fell like a dumb a// I will add this site t my fovorets for your help THA"
SOURCE: I get codes p0700 and p0740 on a dodge grand
P 0700 = EATX (Electronic Automatic Transmission Communication) Controller DTC Present. = An automatic transmission input DTC has been set in the transmission controller.
P 0740 = Torque Converter Clutch. No RPM Drop at Lockup. = Relationship between engine speed and vehicle speed indicates no torque converter clutch engagement.
Yes the Fluid and Filter Change should take care of this. However, Dodge, Chrysler, and Plymouth Minivans have had alot of Transmission problems over the years. Make sure that whomever changes the Transmission Fluid that they use exactly what is specified. Also, do not let any Mechanic talk you into a Superflush of the Transmission. This procedure does not change the Filter.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!
SOURCE: What causes codes 700 and 740 to set on a 2005 dodge grand caravan?
P0700 is just the powertrain control module being signed to turn the check engine light on to indicate alert you to a transmission issue. As far as the other one goes you likely have a failed Torque converter clutch so the solenoid would not fix the problem. You will need to remove the transmission and replace the TC
