transmission is applying max line pressure under normal driving conditions. Checked the pcs wires for any splices and made sure they had power , that all checked out fine. Checked the pins on the connected to the transmission to make sure it was getting a good contact and that is fine aswell. It throws a code ( po748 ) and says electrical. The pcs sensor was checked and worked fine when the trans got built. I read that a bad / dirty maf could cause my problem so I replaced that and still the problem occurs. Also read a bad TPS sensor could cause my problem so i also replaced that and once again my problem still occurs. Has anyone ever had this problem before?
