2003 Chevy Malibu Transmission wont shift past 2nd gear.
So i have tried to resolve this issue with no luck. It began when my car began to over heat. So i pulled over added water and continued. But when i get on the freeway it wont shift pass 2nd gear. I have tried switching out the transmission speed sensor and adding trans oil as needed, But no luck. Any help would be great, thanks.

Supercede:
This bulletin is being revised to add the 2004 model year as well as the Chevrolet Classic model. Please discard Corporate Bulletin Number 02-07-30-022A (Section 07-Transmission/Transaxle).
Condition
Some customers may comment that the Service Engine Soon (SES) indicator is illuminated and that while the light is illuminated, transmission shifts are extremely harsh.
Cause
These types of conditions may be caused by an intermittent connection at the transaxle 20-way connector to the wiring harness interface.
Correction
If a DTC was recorded and the Freeze Frame and Failure Records back it up, a problem existed at one time with the wiring and/or the connectors between the transaxle and the PCM. Therefore, a thorough inspection and/or repair of the wiring harness at the transaxle 20-way connector for one or more of the following conditions may be warranted.
^ The wiring harness is stretched too tightly or other components are pressing on the connector body itself causing a downward pressure on the connector body and possible intermittent contact of the wiring terminals. Ensure proper clearance to any other components and wiring (i.e. hoses, battery cables, etc.).
^ The terminals are not fully seated into the cavity of the connector body.
^ The male terminals in the transaxle portion of the connector may be in the wrong position (i.e. bent).
^ The female terminals may be loose and are not making proper contact. Check the tension with the proper terminal tester from the GM Terminal Test Kit J 35616-A or J 35616-92. If the tension is low, replace the terminal. Do not try to re-form the terminal.
^ The crimp of the terminal to the wire may not be satisfactory (i.e. loose, over insulation, etc.).
^ The wiring connector is not properly seated and locked in position. Ensure proper seating of the connector into the transaxle and that the connector is properly locked in place.

TECHNICAL
Subject:
Slips, Harsh Upshift or Garage Shifts, Launch Shudders, Flares, Erratic Shifts and Intermittent Concerns, DTC P1811 or P0748 Set (Replace Pressure Control Solenoid Valve Assembly)
Condition
Some owners of the above vehicles with a HydraMatic 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.
Cause
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.

I have 2003 Chevy Malibu that won't shift into low gear. It will manually shift into decond but not into third and drive. Inpluged computer and checked all wires to transmission and none were broken. Code comes up 1004 when put on machine. If I put a used computer in will I have to have it calibrated??
