Hi I have a 98 Camaro and it's setting a p0748 dtc for the pressure control solenoid circuit and I'm not what the circuit high or circuit low means is that just another word power and ground? I found the pins for the pcm for the control solenoid but not sure where the problem lies at I changed the internal harness in the transmission and that didn't correct the issue and I'm confident it's in the wire harness between the pcm to the transmission but not sure if it's the high or low the car won't command the up shift during wide open throttle conditions but drives and shifts normal
JA: Sometimes things that you think will be really complicated end up being easy to fix with Chevy. The Chevy Mechanic I'm going to connect you with knows all the tricks and shortcuts. Are you hoping to fix this yourself?
Customer: Yea I'm in the process of hunting it down but just not sure of where to look next and need some insight of some terms high and low
JA: Great! What have you tried so far?
Customer: Changed the harness inside the transmission and changed the solenoid and now trying to trace where the problem is
JA: Is there anything else important you think the Chevy Mechanic should know about your Chevy?
Customer: Well the engine
and transmission is built with mild performance parts that's about it not sure if this issue was already there before I built the transmission or not
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Chevy Mechanic about your situation and then connect you two.
