Will not having an EATX relay installed affect the functionality of the transmission? Trying to diagnose some issues related to the Torque converter/solenoid and realized not only is the EATX relay missing, it's outlet is gone as well. Any help would be appreciated

SOURCE: What are common symptoms of torque converter

common torque converter failure symptoms are: higher than normal rpms at highway speed, rpm jumping in city traffic (press accelerator and rpms spike before you really start moving), lack of pick up, sometimes a loud roaring sound depending on type of converter. as far as damaging the transmission goes... not really, if the torque converter froze up completely then yes but that is extremely rare. the converter is probably worn out which is generally just letting the crankshaft slip before the transmission can get the power

SOURCE: Where is the Torque Converter clutch solenoid

Actually, the Torque Converter Clutch Solenoid is located within the transmission housing that is easily accessible through the transmission oil pan. The TCC solenoid may vary in location dependent upon manufacture but generally it is located as aforementioned. It can cause your vehicle to stall if stuck open or close because it controls loads to the engine via your torque converter which is located between the vehicle's engine and transmission. Also, make certain that you attempt to change the transmission fluid and filter before changing the TCC solenoid because that may be your underlying issue. If not, simply reuse your fresh oil and change the TCC soleniod.

Would lack of an EATX Relay cause the Engine Cooling Fans to Fail to run?

Eatx is the transmission relay. Nothing to do with the fans. Fans quit working because of the fuse, relay,wiring, resistor, and sometimes the PCM.

of what the whole car?

first year of WK in USA.
posted over 100 times here.,

see WK jeep there, the full manual. why not find it your self.?
my wild guess(context not stated)
you scanned the car. and get DTCs unstated, and the fact that the FSM book mentions EATX like 100 of times. ? for transmission? more times really.
and there are 2 transmissions, too....
not stated. either...

to answer the locations question, open chapter 8w,
its all there..
page 10 to 12 cover boxes JB or PDC.

the operators guide has fuse boxes. lost that.
and the FSM , too, to the 9th degree..

P0700, P0750 and P0755 codes I was driving at 65 mph and the 2003 Dodge Caravan down shifter to low gear and the check engine light came on. It will not ship to high gear.

P0700 (M)
Check Transmission DTC's
This code indicates that the EATX (Transmission controller) has an active fault and has illuminated the MIL via a BUS message. The specific fault must be acquired from the EATX via a DRBIII tool. (Input or Output Speed Sensor failures often cause this code and are a common failure part on WJ Grand Cherokees

Shift Solenoid circuit.
Note: If code P1767 (Transmission Relay Always On) is also present: Replace transmission solenoid assembly. See note provided. When transmission is in limp mode the relay that provides power to the solenoid group is switched off. This is normal and is designed to provide operation in one gear only. Engineering department suggests to replace transmission solenoid assembly anytime these two trouble codes occur together. See applicable service manual section (21) for solenoid assembly replacement directions. IMPORTANT: When performing this repair always check torque on all valvebody accumulator cover plate screws. Proper torque specification is 70 inch pounds. If any accumulator cover plate screws are damaged or missing replace the valvebody assembly. NOTE: If any other trouble codes are present do not replace solenoid assembly. See test in the applicable Transmission Diagnostic Procedures Manual
