3 Different Check Engine Light Codes

First post on the forums. Anyways, the check engine light came on today for my 2006 Jeep Grand Cherokee 3.7 V.6, so I went and had them checked out:


I found out that the P0700 one was "Transmission Control System Malfunction", but, I can't seem to find out what the other ones are. Any help would be greatly appreciated.

U0404- Implausable data recieved from ESM, and the P0700 could be from low transmission fluid, the NAG1 tranny wiring bulkhead connector gives trouble and leaks.... Do you have any leaks?

Cant find the "UC404"

esm = shift module.

its the shifter. clean the contacts first; worth a try since the ESM = BIG BUCKS. v6 is 600 for the part.

The P0700 Tranny could be one of many things,i had that code on my last Grand and it went into limp mode and it ended up being low voltage on start up in the battery.

So maybe a dealer or someone needs to find the fault within that code.
