P2738 Pressure Control Solenoid Valve 6 Control Circuit Low Voltage. Whenever you drive, the transmission will go into limp mode every now and then. It will say low oil pressure and throw another code of P0700 MIL Request From TCM. This is a common issue that I have researched and would like to know a way forward. I’ve only had the vehicle for 6 months. Within city limits as long as you don’t push the accelerator too much (50mph within 2 minutes) it runs ok until the vehicle comes to a stop. Also, when you get on and off of the freeway, same issues make it go into limp mode in which you will have to shut the truck off and start up after a few minutes to reset.
