Check engine light came on yesterday on the way home on the highway, kicking hard into gears and running high rpms. didnt have time to take a look until today. Fluids all fine, got it scanned by an OBDII code reader/scanner pulled 4 700 codes (700 codes are only related to trans apparently)
P0700- Trans System Malfunction
P0731- Gear 1 Ratio
P0733- Gear 3 Ratio
P0734- Gear 4 Ratio

Guy said its a possibility it could be trans control module, or trans solenoid, or old sensors. After all the car has 189k on it, trans was rebuilt about 40k ago (before i got the car) and engine has 67k on it. Looks like a fun weekend ahead. Anybody ever encounter any of these codes? What fixed em?

So it turns out it was a simple speed sensor that needed to be replaced

You already found the problem, I was just going to post it. LOL I had the same thing 3 weeks ago. Disconnect your battery for 15 mins to clear the code once it's replaced unless you paid to have it done.

didnt cost me a dime at the dealership, haha had some outstanding recalls... and they replaced my speed sensor while they were at it. it pays to know people at dodge haha
