Unfortunately, it sounds pretty bad, good job listing the symptoms though, appreciate it. Now what I would do next is replace the oil completely (and filter if there is one). Its your last hope of saving the trans, plus you can get some valuable clues. When you drain the oil inspect it closely for metal filings/fragments, and take note of the smell too. Does it smell burnt? Is the oil discolored? Also pay attention for leaks, trans oil level doesn't usually go down unless theres a leak. It doesn't hurt to save a sample of the oil or fragments for an expert to inspect. Unfortunately, if new oil doesnt change anything, then overhaul is iminent. Hope this helps.

Ok,not really enough info to come to a proper solution. It sounds like you have a serious transmission problem. Could be the torque converter clutch or circuit. I really need to know what code is being set when the light comes on to narrow it down abit. If it's a reputible shop, they should tell you what code was found. Chrysler products have a long history of trasmission problems,ranging from internal malfunctions to pcm issues. Could be a simple re-flashing of the tramission pcm. Whatever the case,a flush will not fix it & the battery is pure coincidence. There's also the possibility it's a problem with the electronics for the engine. Being you need advanced diagnostic tools, I'd take it to the dealer or a very good shop. You can't fix this at home.

I know you don't want to hear this but the forward clutch pack has failed, that is either due to wear or a loose of hydraulic fluid pressure inside the trans, pull the pan and look for debris in the pan, if that is only normal small amounts of black goop then the problem is a failed seal in the pressure passages, in any case the trans has to come apart to fix it, so an overhaul will be required. this trans is prone to failure around 100,000 miles. my experience 40 years as an automotive tech, master certified automatic trans technician.

P0700 - Transmission Control System Malfunction.
The code basically what that means is that a malfunction has been detected in the transmission and associated components. There is good news and bad news. The good news is it might be covered under warranty. You didn't say if your vehicle is still under warranty, be aware that you may still have warranty coverage on this since your car is just 3 years old. The bad news is that the P0700 code really means that there are transmission-specific codes that you can't access with a regular code reader. There is a part called a TCM - transmission control module that works in a similar way to your PCM. The TCM handles the transmission electrical "stuff" and it stores further transmission codes.
If you want to pursue the issue yourself, you'll need to get your hands on a higher end code reader, or take it to the dealer or a transmission shop to get the actual transmission trouble codes read. Personally we recommend you get a shop to read those codes for you. The other codes are communication codes, we recommend you clear those codes after you fix the P0700 code and see if they come back, they could be related to the "main" transmission issue. The other good news is the fix for this may just be a software update that the dealer can do.
P1728 - Transmission Slip Error
THis code indicates that the transmission is slipping. When the computer that controls the transmission detects a fault code like P1728, it will put the transmission into a "limp" mode. When the code is cleared and the transmission will function properly until the slippage occurs again. To resolve this problem, you will need to get your transmission overhauled.
Hope help with this.

what year and model is your automobile? if it's an older fullsize dodge, they didn't have vacume modulators.
they used a solid metal rod to move a throttle valve located on left frount corner of transmission throttle body with usually combined with shift lever shaft.
if fluid, and filter change seemed to solve problem briefly you may have dirty, sticking valves in transmission valve body.
you can buy transmission flush at parts store follow directions on container.(DO NOT OVER FILL!!!)transmission
hope this helps
