Question about 2000 Buick Century
Some owners of the above vehicles with a Hydra-Matic 4T65-E transaxle may comment on harsh upshifts or harsh garage shifts, soft shifts, shudders on hard acceleration, or shifts erratic. These conditions may appear intermittently or set a DTC P1811 or P0748. During diagnosis, a low or high line pressure (actual versus desired) may be observed.
The above condition may be due to any one of the following which may affect line pressure output:
• Sediment inside the pressure control (PC) solenoid valve, causing the PC solenoid valve to mechanically bind. • Sediment in the valve body, causing the torque signal regulator valve to stick. • Incorrect transaxle oil level.
To verifiy the exact failure, a line pressure check will need to be performed.
Hope i helped you.
