Check engine light?

Any transmission related services recently?

[putter]

it has a code for high voltage for the egr valve the engine light was on prior to the concern hapening if i remember correctly?

no trans related service done recently

Transmission shudder is typical in many Dodge / Chrysler transmissions. The fix is change the fluid and make sure the fluid used is the spec. ATF+4.

Incorrect EGR can cause a range of driveability problems. Surging, lack of power, low idle, crank no start, etc. It might be worth pursuing the Check engine light first. Since you think it was already on before this happened it is entirely possible for whatever happened to trip a new code that will more accurately lead you down the right path.

Have the codes checked again and see if there is anything new.

They had a problem with the torque convertors and pumps that year. So my best guess would be the front pump assembly and torque convertor. Make sure the fluid is full.

I'm with AirJer on this one. Check the codes and see where that leads you. My uncle has a 96 caddy and they picked it up dirt cheap cause the previous owner thought the tranny was going. Turned out that it needed plugs and wires. Fixed a misfire problem and reset the computer and the transmission problem code went away.

Definitely check out what that code is about. You never know with that stuff what it will make the vehicle do.

I do know they had shudder problems for a few years there though. My dad's durango was doing it and with a fluid/filter change it went away. I am pretty sure that there is a oem mopar additive out there just for that problem though. I know that lubegard makes a shudder additive specifically for dodge too(im pretty sure they are who made the oem additive). We carried it at oreillys when I worked there and I think it was 15 bucks.

it turns out it was the egr valve that was the problem. what i did was to confirm it was i unbolted the egr valve from the engine and cut a piece of pop can and plugged off the port rebolted the egr valve problem went away.
