Hi,

I got the blinking AT Oil Temp light and check engine light after doing some engine work recently so I read the code and got DTC P0748 - Pressure Control Solenoid (Line Pressure Duty Solenoid) Electrical. I drove the car around and noticed shift shock from first to second gear consistently.

I did jack up the tranny by the tranny oil pan and dented it a bit. Could this have damaged the pressure control solenoid? Or is this simply an electrical issue where something is not connecting? I do not know where the pressure control solenoid is or what connector to check. Does anyone have any insight into this problem??

Thanks in advance

Thanks Ferret,

Here is another very useful few links on the matter from NASIOC.

Cheers. I will update with results.

Some results.

I got a multimeter and went through the steps in the above link. All connections were good. Turns out when I jacked up the tranny by the tranny oil pan, I bent it in and broke the connection on the pressure control solenoid - and expensive little mistake.

Dealership wants $250 for the part and that seems crazy to me so I am currently trying to find a used part. Can't seem to find it online. If anyone is wondering it is the red solenoid when you rip the pan off. Once I get this replaced it should fix the problem. Will post final outcome within the week.
