Replace Transmission or Replace Parts 05 Dodge Neon

Question

I recently purchased a neon from a family member in hard times. The car starts and runs but does not move when shifted out of park.. NONE of the gears work. I believe it did go into a limp mode before I got it, but that does not work either.
I hooked up the scanner and found a list of codes.
P0700 (twice)
P0731 (twice)
P0501 (twice)
P0841
P0846
P0715
P0720
P0740
I am somewhat mechanically inclined, and I would be able to r&r the tranny with a new or rebuilt, or replace parts on the "outside" of the tranny. I do not feel comfortable rebuilding the current one.

Any help, direction or guidance would be greatly appreciated.

Thanks in advance,
Brandon

Answer 1

P0700 Transmission control system Mil light requested

P0731 Gear ratio error in first

P0501 Vehicle speed performance

P0841 LR pressure switch sense circuit

P0846 -2 / 4 pressure switch sense circuit

P0715 Input speed sensor error

P0720 Output speed sensor error

P0740 TCC out of range

This is more than a transmission error, it is more of a problem with the TCM and the PCM, certain indication are that the PCM does not see input from the TCM . This is from either no to low fluid pressure, If the pressure is good, switch out the solenoid pack,
