please helppp!
 

hello everyone. i just bought a 2000 grand cherokee and i have 7 different codes. i need help finding the problem. they are all tranny codes:

p1734- 2c pressure switch sense circuit
p1784- LR " "
p0770- 4c shift solenoid valve
p0760- OD shift solenoid valve
p1737- ms solenoid
p0765- UD solenoid
p1768- tranny relay

i was wondering if all these codes could be caused by a faulty tcm. if not does anybody know what i need to do to fix this? thank you. i can use all the help i can get!

Might be a TCM issue or a loss of voltage issue. Start by checking the battery and charging system to make sure it's ok.
