I had an accident with my '03 Neon SXT automatic on the front left side. I changed out the cam sensor and trans output sensor based on codes. Got the new bumper on, new bulbs, tire, wheel, etc...and thought everything was good to go. Now it's shifting hard from first to second about 10% of the time, and sometimes not shifting out of whatever gear it starts in (another 10% of the time) BUT it will still go into reverse! Rest of the time it's fine. When it won't shift it throws codes and won't allow me to change gears unless I shut the car down. I'm getting errors P0700, P0731, an P0736. Since I just replaced the trans output sensor I can only assume that either I got a faulty trans output sensor or the socket for the sensor was damaged in the accident, there's something going on with my transmission fluid (dirty or something of that nature, something going on with the trans input sensor, or something else outside of my knowledge level like the computer needs to be reset or something of that nature. All I have to do to get it to reset is turn off the engine and re-start it. Problem "solved". TOTALLY lost. Have a newborn so would rather not guess and change parts one at a time and waste money frivolously as you can imagine. A little help from more mechanically inclined people would be most appreciated. Thanks in advance!

Would the stealership be able to plug this into a computer and tell me EXACTLY what the issue is so I can fix it myself?
They probably could , for a FEE $$$

The codes dont tell you just what is wrong it just tells you the circuit the controller sees not working right. You actually have to know what you are doing to fix some of the problems. Ron

Throwing codes P0700, P0736, and P0731. P0700 trans control system, P0736 reverse incorrect ratio, P0731 gear 1 ratio incorrect. Kinda what I figured re the output/input sensor...would go straight into limp mode and no speedo like before...fixed that already. Would rather know what the issue is based on these codes, and fix myself. If I have to I'll take it to them if their equipment is capable of telling me exactly what is wrong and then I'll fix it.

No delay when going through any of the gears in forward, but jumps a bit sometimes from 1st to 2nd...nothing when switching from forward to reverse or vice versa. Fluid levels all check out and no dents in the pan. Was not quick learned after repairs. Replaced cam speed sensor and trans output sensor.
Will see if I have time this weekend to tear into her to check for everything recommended. Thanks guys! I'll report back. Any other suggestions welcome in the meantime.

It needs an input speed sensor.
