Laundry list of codes.. need help!!

[Dakoda]

ok so my car has been acting up lately doing things like revving to 3 grand then coming back down to around 1100, cutting out while cruising, very randomly it will shift hard, and somtimes its hard to start. Also everytime i take off it makes like a sort of humming/vibrating feeling. I've taken it to oriellys several times to have it read and the only code it would ever give me is an o2 sensor code. So now today i took it to autozone and they gave me all these codes:

P0730
P1260
P1811
P0141

I know the last one listed is a rear o2 sensor which im not to worried about but any help with the other ones would be greatly appreciated.

p0730 is listed as incorrect gear ratio

read up on all of them just wanting peoples input on what to do...

fix the codes depending on the cost and the year and mileage of the car

1811 = If a shift into any gear other than reverse and forward engagements takes longer than 0.65 seconds to complete, code P1811 will set. The Powertrain Control Module will then command maximum line pressure inside of the transmission, resulting in harsh shifting. The PCM will also command the check engine light or service engine soon light to be illuminated when P1811 is set. Basically, the PCM is sensing a slip, and is increasing line pressure to maximum in order to prevent the transmission from hurting itself further.

p1260 appears to be an anti-theft issue.. says it can cause hard starts.
