Funky Dakota Issues
Hello and thank you to anyone who helps me solve this issue.
Recently, and I mean all within about 24 hours, my truck experienced very different symptoms. The first was that my cd player will no longer eject cds. While this is possibly not related to the other 3 it is just weird it happened at the same time so it is worth mentioning. The next was my fuel gauge stopped working, then the check engine light came on. I received 3 codes, B2100, P0463, and P0700. After looking up the codes they stand for the following:
B2100 - Low Battery Voltage
P0463 - Fuel Level Sending Unit Volts Too High
P0700 - Check Transmissions DTCs
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)
My first thought was this had to be electrical so I replaced all battery hardware and expertly cleaned the terminals. Didn't fix. I then checked all the fuses (couldn't check relays) and found one blown for towing lights ... and it didn't fix it. Now I'm just confused and would really appreciate any help. Going through the forums I've seen a ton of posts about the P0700 code but I'm not having any noticeable tranny problems like most the posters complain they experience. The tranny is less than 30k miles old and is shifting great. I'm feeling or hearing no weird noises or anything.
As far as the truck it is an 05' Dakota 6 cylinder standard model with only the towing package upgrade. It has just over 140,000 miles, still runs good, and gets it's EPA estimated fuel economy. I just recently dropped the tranny pan and replaced the filter, all the fluid, and the surrounding gasket. The oil is changed approx. every 3k but as I drive a lot of highway miles if I go to like 3.2k or so I'm not overly concerned. I use all synthetic oil with usually mobile-1 filters unless a nicer brand has a really good sale on. It does have a cold air intake long with - and I'm not sure of the name as it was preinstalled when I bought it - an oil airater. For the cd player it is the standard 1 disk and is stock. The previous owner was a car mechanic so here is hoping he took care of it like he said he did.

Funky Dakota Issue
Ty for the welcome.
I had the battery unplugged for approx. an hour and a half to 2 hours. Not 100% sure because I lose track of time while working. The battery voltage tested fine and I hooked it up to a charger while it was disconnected from the vehicle. Just reading through some other posts I realized I never tested the battery with the vehicle turned off. While running I was getting 14.4 or so. Let me get a shower and I'll go test it :-). Up this morning searching for answers so haven't left the bedroom yet lol.
After that 1 1/2 to 2 hours the check engine light went off then came back on.

Back, I tested the battery cold and it read 12.5 Vs which I'm happy with. Are you suggesting I reset and check the codes again now? After I disconnected it the first time the check engine light went out and then came back on but I do not personally own any code checking device.
I've just seen some funky things happen because of low battery voltage, bad connections/grounds, etc. Sounds like you redid all the connections at the battery itself, did you also check the other end of the ground wire? You say the truck is running fine?
