So my car lurches when I am accelerating and then the other day it wouldnt shift when I was going down the freeway at about 60 making the RPMs go between 5500 and 6000. I got it checked out at Auto Zone and the codes are PO720, PO731, PO700 and PO732. My boyfriend is now saying it may well just be the transmission output speed sensor. Where is that located on a neon?

Re: 2003 Dodge Neon SXT
Do check the motor mounts! Start the car, have a helper shift from reverse to drive! Is there a lotta engine movement?? Replace the faulty mounts. My quess it is almost flipping over! The output speed sensor likely on the back middle of the trans. There are only 2 connectors, the other is backup lights. Best I can do at this time! Frankster016

is it grinding when you try? try to turn car off hold in clutch put into reverse and then start car if it pops right out you need to get it to a transmission shop. i recently replaced a transmission in an SXT that had no reverse, all it would do it grind and pop back out
same thing happened to me, with a 2003 neon sxt..... but tranny went into error and wouldn't shift out of first til i reset the engine error, tranny and gages were fine (til it got cold). i had to warm the car up, reset the error to go anywhere. i was told it was the drivetrain computer. but i'm still checking other things.
the trans shift solenoid pack is bolted to the side of the trans closer to the radiator. it is rather large and there are three 10mm bolts holding it to the trans. it is under the input speed sensor and just under the spot where the cooler lines go into the trans.
