Transimission problems

A few weeks ago when i was driving home from the ski hill i started running into some transmission issues. My car had problems shifting at all, only shifting between 2nd and 3rd gear. Since then I have completely lost 2nd gear and can only drive it in 3rd gear as it will not shift from there (not that i am driving it much because of the problem).
I finally got around to scanning te engine and it did throw a "couple" codes. 10 that delt with the transmission directly.
P0713
Transmission fluid temperature sensor
A circuit high

P0748
Pressure control solenoid a
Electrical

P0776
Pressure control solenoid B
Performance stuck/off

P0778
Pressure control solenoid B
Electrical

P0974
Shift solenoid A
Control circuit high

P0997
Shift solenoid B
Control circuit high

P0986
Shift solenoid E
Control circuit high

P2716
Pressure control solenoid D
Electrical

P2743
Transmission fluid temp sensor
B circuit high

P2759
Torque converter

Is this going to be a full transmission replacement issue? or is it possible to save it still by just replacing solenoids.

 

Did you check your fluid level?

 

Yes my fluid level is fine.

 

Well, have to check the simple things first.

This has a TCM? I would check the wiring to it and all power and grounds. That's a whole bunch of codes to get all at once.

 

Welcome to the forum!

May be outta this universe, I would do a quick visual on the harness(s) to ensure no malicious intent from rodents looking for something to naw on.
