I’m happy to help further over the phone at https://www.6ya.com/expert/kenneth_3efc1f8510674f04

what are the names of the codes? are they abs codes?

p0731 transmission shift problems
p0841 solinoid problems in the transmission
p0846 fluid level
p0700 solinoid stuck or sticking hard shifting
there is a solinoid in the transmission that shifts the trans and downshifts when stopping this is a problem you generally don't want to do your self

It may be a shift solenoid or a speed sensor look up the codes online google your cars year, make ,and model and be sure the fluid is not too low, check the fluid level warm while the motor is running.

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

The codes listed all point to the transmission being in bad shape or some wiring got crossed. Check with a trans shop for an estimate.

replace the input speed sensor to transmission and the wiring pigtail all are available at your chrysler dealer take your vehicle registration in to the parts counter so they have your vin # to get the right part and it is the front of trans by fluid linres to radiator.
