First lets define the codes P 1738 shift time error this is a transmission issue
P1784 Transmission mechanical problem 1st and reverse
P0736 Reverse incorrect gear ratio
P0120 Throttle postion sensor switch malfunction. Here is the fix this now make alot of sense when your TPS sensor fails you will affect the performance of the transmission and hence the transmission codes so replace the throttle position sensor this is much easier than the cranksensor and here is the good thing this sensor has no adjustment just drop and go

Testimonial: "Thank you for honesty & help. I finally got someone to give me a straight answer. Will the transmission problem cause the car not to start? Thank you "
The actual not starting is probably your Throttle Position Sensor. (P0120) You can check the connection and try to clean it or replace it.
I will upload a picture to show you where it is located on your car.
You will have to remove the air filter housing to get to this but it is just a couple small bolts holding this in.

remove the gas cap and have someone listen while you turn the key to the on position. You should hear the fuel pump humm for about 5 seconds. The first 3 code are for transmission failures, P0120 is for throttle position sensor circuit problem. this could simply be a ban connection due to corrosion.
